Title: Windows 10 failed update to 1803, maybe an Avast problem?
Post by: Navvy on May 22, 2018, 05:24:15 PM
On a friend's Compaq Presario CQ58 I used Settings to apply Windows Updates, and it downloaded and tried to install the latest feature update 1803.  Unfortunately it now just asks me on a blue screen to select a keyboard layout and then on the next page it has a Continue button which takes me back to the keyboard layout selection again.  System Restore points no longer exist, and there seems no way to get to the machine working again.  Looks like I'll need to do a clean install of Windows.

Reason for posting here is that a google search came up with this page https://www.yourwindowsguide.com/2018/05/what-if-your-computer-is-broken-after-1803-update.html

This page indicates that most people who've suffered this problem have had Avast installed, and they are advising people to uninstall Avast before applying the update.

Has anyone on the forum seem this problem?  It isn't just the Avast UI failing to run - it's behaving as though Avast has crippled part of the windows update, which has happened to me previously with the Anniversary update on a different computer.

Note that this Windows 1803 feature update is being delivered automatically to anyone who uses Settings, Windows Update.  In my case I was on a mobile hotspot metered connection, and it asked me for permission to download a very small 0.1MB update, and then used that permission to automatically start the 3GB download.

Quote
Reddit user gcdrm, who says is working at a small computer repair shop, reveals that multiple systems upgraded on May 20 and May 21 experienced the same issues.

“Thus far, the only solution we have found is a Windows reinstall,” they posted. “It appears that everyone that has fallen victim to this problem has been using Avast Antivirus. However, this problem has only occurred on systems that attempted the 1803 upgrade in the last two days. This infers that a very recent update to Avast is interfering with the upgrade process. It appears to be damaging read/write permissions on the problem computers.”

While neither Microsoft nor Avast acknowledged the issue, users who are being offered the upgrade to Windows 10 April 2018 Update are recommended to uninstall the antivirus before beginning the process. No action is required for users who have already completed the switch successfully.

Thanks @Evjls

I think Avast had updated on Friday 18th, and the 1803 download started on Sat 19th and completed on Monday 21st, so this does match.  The laptop now seems to have no network connection at all, as the drivers for many services haven't started.  So there is no possibility of Avast or Microsoft being able to issue any retrospective bug fix online.

I'll try getting into Command mode and see if I can run aswclear from a USB drive, as that will show whether Avast has corrupted the update process or is just preventing the upgraded Windows from running.

Update - I've run AvastClear, and it hasn't made any noticeable difference.  Windows is still unusable, and I'm getting "C:\WINDOWS\system32\config\systemprofile\Desktop is not accessible. Access is denied."

The network and audio icons in the system tray are both showing red-X. The hidden icons button contains a golden padlock.  What does that mean?  Left-click or right-click on the Windows button in the bottom left don't work.  Task Manager is about the only thing that does work.

I recommend you to do a clean installation of your windows to clean up the mess and the incompatibility issue
or if you don't want a clean install, just perform a repair of windows AFTER UNINSTALLING AVAST

windows 10 1803 itself is quite buggy and hasn't been very stable yet to many users

Hi guys, thanks for reporting. We are working hard on reproducing the issue here, but so far no issue found with Avast at our test machines. Definitely, it seems that all affected users were also using Windows at the time of the attempted update, so that is also a possible suspect. I'll update here once we find more info. Thanks!

Lukas.

Microsoft temporarily disabled the updates on version 1803 on PCs with Avast. We are working together with MS to find out the cause of this issue, but unfortunately right now neither MS nor us are able to reproduce the issue.

MartinZ, Lukor - You said you are uneable to reproduce the problem? - I will be happy lending you PC of my parents for while. Im paying for their AVAST licence for their PC being safe a bit and now I have to go to them and repair their PC because Windows forced updating their PC yesterday even that many peoples have been reporting in previous days that the spring update conflicts totally with AVAST !
(even Im angry, really - if it could help, the PC may be inspected, Im based in Prague, email is in my account here)

oh, what for a suggestion! Should Navvy after succesfully perfoming clean reinstallation of Windows start to experiment with disabling, enabling AVAST and then performing the spring update again??? Navvy is writing that his PC is dead now (same as PC of my parents is dead and many, many PCs all over the world), have you read his post at all?

Hello

i found some cain of solution, is in here i made the post. so i copy and paste....

I just step whit this windows10 and avast issue I can reinstall the system without losing applications or docs or conf

This windows10 dont want to install the spring update or do anything, just load the ER after read everywere, it look like a problem with avast

How i manage to solve this, i'll try to explain.

In the ER (environment recover) I manage to load the windows10 with the black desktop, is some cain of safe mode without the save mode-... weird, load some things. I connect the network cable just in case.
Go to troubleshooting and them try to load another operating system, the option. In my case i have 3 options, rollback, and 2 option with windows volume 3, i choose the third, and try several times to load the black desktop be patience take sometime to load.
When load, execute tasks manager, control+shit+esc, and execute any browser, internet explorer those the tricks and search avast uninstall. download the app, execute with win+r and uninstall.

After that i execute from a USB the installer of the spring update ISO and install the win10 and preserve all data and applications.
It takes almost several hours,4 h. to restore the win10 but i recover all.
Hope it helps

@Spec8472  @MartinZ
Could you please give a clearer description of which log file you want to see?

I have now done a clean install of Windows 10-1803.  Fortunately this machine wasn't used for anything except browsing, as I've now lost the Word and Excel that were pre-installed on it.

I'm now able to see the C:\Windows.old.000\ directory which contains the user files from the original installation.  This contains a Windows folder, and within that there is no Sources folder.  However, there is a Panther folder, and that contains various files that look like logs.  One is MigLog.XML but that is 125MB.

I'm now using Defender, and I haven't installed Avast on the clean machine.

On my own machine I've switched Avast to passive mode, which required a reboot.  Defender eventually enabled itself, but needed to be manually updated (last Defender definitions update was several years ago).

The Avast icon has appeared again in the system tray, and when I hover over it, it says "Avast Free Antivirus - You are protected".  This seems to be a bug, since Avast is not providing protection.  I've set my broadband connection as a Metered connection to prevent the 1803 feature update.

Incidentally, the Microsoft Media Creation Tool for creating a Win10 installation USB seems to have a problem too.  It failed repeatedly at 50% despite running it as an Administrator.  Eventually I used it to download the ISO and used Rufus to put it onto the 16GB USB drive.  One difference I spotted was that Rufus insisted that the ISO needed NTFS instead of FAT32, which the USB drive was previously quick-formatted to.

its a shame that until now there is no recommendation what to do from AVAST . No useful response, no information.
I personally am going to follow the steps from reddit forum (thecomputercellar).

@pk
I've just uploaded the entire compressed Panther folder 11.6MB (246MB uncompressed).  The filename contains my email address as suggested, so search for "wrgbitm".

Hope it's worked, as I simply used Edge to drag & drop into the ftp.avast.com/incoming folder.

No issues updating to 1803 here, Avast not even disabled before the update. But still on 18.3.2333, not sure if it is a 18.4.2338 issue. Won't be updating till it is sorted...

My computer did the Windows update early this morning, and it made a total mess of things. It got close to completion after several restarts and then started asking me to choose a language for the keyboard. Every time I selected one, it restarted and asked again. As others have reported, my options were very limited. I couldn't use system restore, or repair, but could boot up from an older version, but I got a black desktop with just a recycle bin in the corner, and trying to open explorer resulted in something about a token error.

I discovered the website link somebody posted earlier, suggesting it was Avast that was causing the conflict. I downloaded the removal software on a USB, deleted Avast using the task manager, and then downloaded the 1803 update (about 4.4gig) from a neighbour's computer, because my terrible internet connection was telling me it would take 6 days! I extracted the contents of the ISO onto a USB stick, ran the setup.exe via task manager again, and am very thankful to have my computer back up and running this evening.
I've been using Avast almost since its inception, but sadly after this I won't be returning. It's been a very disruptive and stressful day.

DANGER!!! DANGER!!! DANGER!!! DANGER!!! DANGER!!!

I tried to fix this problem myself by reinstalling Windows 10 and asking it to keep my applications and files. It DELETED ALL MY PERSONAL FILES. I know that for many others this solution did work but it really depends how screwed up the update was. In my case it seems that it never backed up my user files to windows.old as it is supposed to do and then it restored empty directories instead of my desktop, documents, videos, pictures, etc.

Microsoft support says they will have a solution in a couple days and will then help me restore my files. I doubt they will be able to as even EASEUS can't find them. But in any case, I recommend others to wait a couple days if they can to see if they can get a proper fix.

Hi everyone,

In cooperation with Microsoft we have identified an element of the latest Windows 10 1803 update that is incompatible with the Avast Behavior Shield, causing the aforementioned update to fail in some instances (related to a timing issue, Internet connectivity issue, etc). Luckily, we have found a way to prevent the problem and are now automatically pushing a VPS update to all customers which makes sure that the problem doesn't happen.  The VPS number is 180524-08; all users running this version (or later) should be 100% safe.

For those who've been already affected by the issue, here are step-by-step instructions to bring your computer back to life.
If done properly, no files or data will be lost and no apps will disappear (= computer will be back to normal).

Things you will need:
- 8GB or larger blank USB stick
- a functioning Windows PC to use briefly (another computer in your home, a friend’s computer, even one at a library or print shop)
- about an hour of time

Steps:
1. Turn on the problem computer.
2. At the blue screen, choose your keyboard layout’s language. (e.g. "US")
3. Choose "Use another operating system".
4. Choose the second option, "Windows 10 on volume X" (X stands for a number)
5. Wait for the computer to boot to the desktop (if necessary, enter your password to login). You may have to wait a long time for the desktop to appear, while the "update" gets ready.
6. Once the desktop attempts to load, close any error messages that appear.
7. On a functioning Windows PC, go to www.microsoft.com/en-us/software-download/windows10 (http://www.microsoft.com/en-us/software-download/windows10).
8. In the "Create Windows 10 installation media" section, click "Download tool now".
9. Run the tool you downloaded, and follow the simple steps to create a Windows 10 installation USB stick. This will erase any existing contents of your USB drive. The only option you should check is to make sure it is a 64-bit or 32-bit version. Your computer is MOST LIKELY 64-bit if it's reasonably new.
10. On the problem computer, right-click any blank area on the taskbar, then click "Task Manager".
11. Click "More details" so that you can see the menu bar.
12. Click "File".
13. Click "Run new task".
14. In the dialog box that appears, check the box "Create this task with administrative privileges"/
15. Click "Browse…"
16. Navigate to your USB drive and select "setup.exe".
17. Run the file and follow the steps to "upgrade" Windows. Uncheck the boxes for "check for new updates" and to "help make this version better". If you are asked what you want to keep, make sure you tell it to keep everything!
18. Let the process run, which may take some time. Once completed, the computer should be back to normal, and fully up-to-date. You may need to re-login to your Microsoft Account.

(instructions provided by The Computer Cellar (http://www.thecomputercellar.com/), many thanks for that!)

In the meantime, we continue to investigate the this issue which appears to affect only a small subset of our customers.
BTW at this stage, we know it's not an Avast-specific issue as the problem affects other software as well. The instructions above should work in all cases.

Many thanks,
Vlk

Hi Vik
Some additional info which i hope will be useful......
Following on from corrupted win10 1803 update, pc reset and ending up with a working win10 ver 1803 that had removel all my installed software including ms office pro 2010.  I tried many times to reinstall, using different media but each time office got to 65%, whizzed to 100% briefly, rolled back to 50% and then gave "microsoft office pro 2010 encountered an error during setup" and a close button.  I ran various fixes to no avail.

Believing it was a win10 1803 corruption problem I gave up and completely rebuilt my PC with win10 1709 dvd i had made in march 2018.  The rebuild went well and surprising tho it may seem the Feature Update to Win10 ver 1803 via windows update worked perfectly.  However, on then trying to install ms office pro 2010 on this new build it failed at the same point and with the same error as the original build!!  I tried multiple times with various copies of the media.

So as this rebuild sort of proved this error had not been caused by the corrupt 1803 build I then temporarily disabled all Avast (free) anti-virus shields and re-tried the MS Office install and it completed without error!  I have never had to disable shields in the past but maybe this new version of Avast (ver18.4.2338 build 18.43895.0) is the problem.

To further confirm it is an Avast problem when windows update found an additional cumulative 1803 update and a number of office updates these to failed to install.... Again i did 'Retry' a couple of times resulting in the same Failed to install' error.

Switched off Avast shields and re-tried windows updates and they All Installed.

Conclusion:-  Avast Free ver18.4.2338 build 18.43895.0 will Not allow any fresh update/install to Office Pro 2010 on a Win 10 1803 build.

Hi Bob3160,
I too wished i had first looked at page 115 of the thread you suggested prior to starting the Restart after my pc had downloaded the update.    Unfortunately i didnt as i have never had a problem previously with any of the large updates - hey ho  ;D

A question though please.......  Why after a fresh rebuild and with Avast active would a clean install of Office not work?  I could install Adobe, MWBytes, Realplayer etc etc etc but not Office whilst Avast shields were active. Plus later on would not install the office specific win updates again without shields disabled??  I have never had to disable shields to allow an Office install previously.  What has changed with Avast?

Any thoughts would be appreciated

A few comments on your advice about how to recover a corrupted computer.

Firstly, the Media Creation Tool wasn't able to work correctly on a FAT32 USB flash drive of 16GB, as described previously.  I had to use Rufus to install an ISO onto the same USB drive formatted as NTFS.

Secondly, on the problem computer, right-click (or left-click) wasn't working on the Desktop.  I don't remember whether I tried it on the Taskbar, but it certainly didn't work on the Windows icon.  It changed the appearance of the Windows icon, but did nothing.

I had to force the problem computer to boot from the USB drive, and there wasn't an option to upgrade an existing Windows.  Recovering didn't work, and I had to do a clean install and lost the pre-installed MS Office and all other programs.

A suggestion - why doesn't Avast use the notification popup to warn people that there is a problem with the Update?  The popup could include a link to the relevant post on the forum.  Most Avast users won't even know the forum exists, until it is too late.

It is actually possible to resolve the entire thing without another computer or even without using a USB stick. Or at least, it was for me - I did briefly need my phone, but that was due to an additional problem which not everyone may encounter.

What I did (after many hours of searching online for solutions) is as follows:
- Login to your account on the corrupted computer (as per Vlk's steps 1-5), but you don't need to click away the error messages (just Alt-Tab them)
- Hit Ctrl Alt Del, then open Task Manager
- Go to Users tab, right click your account, select Manage User Accounts (If you don't see any accounts listed, try signing out and in again)
- This will open a Control Panel window, where you click the arrow pointing up until you get to an Explorer window, from where you should be able to open a web browser, access your downloads folder, etc.
- Then download the update as per steps 7-9, but select the ISO version, download and save directly onto your computer.
- Mount the ISO (right clicking on the downloaded .iso file should give you a 'Mount' option), then run setup.exe

I had the additional problem that the Media Creation tool wouldn't work on my computer, blocking me from downloading the update. I finally found an article ( https://www.askvg.com/tip-get-direct-download-links-of-windows-10-iso-from-microsoft/ ) explaining that there is actually a way to bypass the tool entirely and directly download the ISO update, but you can only access the direct download link if you open it from an OS that isn't Windows 10. Any phone with internet access should do the job, and will allow you to email yourself the direct download link, which you can then use from your affected Windows 10 computer to start downloading the file. Once it's on the computer, mount it and run setup.exe .

Hi Avast! I had been messaging MS ever since my Windows 10 system completely crashed with the described symptoms.  No adequate response from them.

I am not sure who exactly is to blame, considering the oblivious difference in scales between MS and you, I would rather chose MS. Especially since I read on MS forums and on reddit that many affected users never has anything to do with any of your products?!?!

Their developers were acting... not sure if IRRESPONSIBLE is enough in its meaning. It is a sad, very sad story.

The notorious Windows 10 1803 update - that I have been trying to avaiod - but didnt really realize how deadly it would be, finally pushed to my system at about 22h 0n 24th may.  After hours of rage - I finally managed to load a previously stored image backup from a WD external device and to restore the system to a February 2018. I didnt know where exactly to search the web for possible solutions, just tested almost all the available options after the Choose your keyboard screen. Didnt have another PC to assist the steps from MS and reddit, only my android phone at hand...

I have been using avast almost ever since its birth back in time, on all my devices. Since I can not get rid of MS - because of obvious reasons, I just parted with avast.

This horrible situation never happened to me before.

Now that I read here, on reddit and on MS- that days before me - the problem had been already reported - by hundreds, located, MS pretending they would stop the update from pushing into further Avast installed PCs days before 24th, you here saying before my personal disaster - had been pushing avast fix update - again before my disaster - sounds - how to call it? ... lame? Nothing of all that reached me. And My pc was restarted same morning of 24th of may - nothing, it stayed on - all day long on 24th of may with stable internet connection?!?!

Hi guys, thanks for reporting. We are working hard on reproducing the issue here, but so far no issue found with Avast at our test machines. Definitely, it seems that all affected users were also using Windows at the time of the attempted update, so that is also a possible suspect. I'll update here once we find more info. Thanks!
Lukas.

I updated my two computers to 1803 on the Microsoft release day while running Avast Internet Security. Both computers were updated through Windows Update, it took about 20 minutes for both computers, and I haven't had any problems with them.

I didn't disable Avast, or any of the shields, or make any special preparations for the update to 1803. I have also updated the two quality updates Microsoft has released since the update to 1803, one being KB4100347: Intel microcode updates on 18/05/2018, and KB4100403 (OS Build 17134.81) released on May 23rd again without any problems or preparation to do the updates other than making sure my file/folder backups, and disk image backups were all up to date.

BTW I also run Malware bytes alongside Avast, and use Windows Defender's manual scan option once a week as a 'second opinion' scan of my computers.

This is just to let you know that not all Avast users are having these problems...

I think it would help if Microsoft Update required users to make a conscious decision whether to make a backup (or not) before starting any major update like this.

This would give users an opportunity to research whether there are any known problems, and if necessary disable some software to prevent possible conflicts.

The current system of starting an upgrade just on the basis that the user isn't busy, means that their backups won't be as up to date as possible.

It would also be useful to know if upgrades can take place without an internet connection, if malware protection has to be disabled.

I have suffered a catastrophic failure as a result of this issue, the blue screen of death. I am very disappointed with Avast as I am a paying customer and have had no support whatsoever, no acknowledgement of the problem, no apology whatsoever.
I called out an IT technician after 4 days of downtime, and following the Avast Support approved blog, he reinstalled Windows 10 from a flash drive, undertaking an installation recommended by Avast to retain existing applications. This procedure did retain all applications except Microsoft Office 365, which I eventually reinstalled. However it has wiped all data, photos music etc. Nothing to be found in windows.old and so far having analysed all files on the laptop, no sign of missing data.
I will be cancelling my subscription to Avast.
I am a personal user but for those of you who are Avast business users my heart goes out to you, if you have lost all your data.

User data never gets wiped unless you say so. If your "technician" deleted it, have a beef with him, not avast! (regardless of what caused the problem).

When I  pressed "I forgot my password" I got "Windows cannot  connect to the ProfSvc service. Please consult your system administer", which I don't have. Pressing OK put me back to the blue screen that I started with! Will there be an updated fix to allow a pin number to be used?

People only have themselves to blame if they don't do a weekly backup and blame Microsoft and avast when they have bsod and lost all all data,as everybody knows you should have at least 2 backups on hard-drives.

after all its free in widows 10 and works great...

Both my laptops have had problems,first had constant bsod and had to restore,then tried again a month later and went through fine.

second laptop crashed and had to restore and downloaded the ISO file to flash drive,disconnected from the network and disabled avast and that went through fine as well.

I know you shouldn't have these problems from Avast or MS...

But always create a system image before upgrading and do one every week.  :)

This has saved 2 laptops from major problems.

Windows 10 did an update ( normally it asks, but not this time), and I came home basically to a blue brick.  Same as others posting,  keyboard layout then next page gives various options that are useless .  I have tried everyone to no avail, the furthest I have made it to was an older version, but it will not accept my password.  Nothing I do works.  I also made Create Windows 10 installation media USB, but that does not work.  Tried getting into the command prompt reads not enough memory resouses and x:\windows\system32.  Bios, does not give me options that I have seen online from microsoft ect.  I would like if somone could go step by step for things for me to try, and do them one at a time.  Not a computer expert, but I have always been able to resolve my problems in the 17 years being a computer user.  HELP thanks :)

See what happens if you download the removal software  https://files.avast.com/iavs9x/avastclear.exe on a USB, delete Avast and  the next step would be a re-install of Windows from your flash drive.

I have a question that hopefully someone can help me with.

The 1803 update is downloaded to my computer and I have postponed the install for about week, but any restart will install it. That said, I have uninstalled Avast entirely and backed up my important data. My question is, do you think it will be safe for me let the updates install now or should I wait? Also, since the folks at Avast said they have a fix, should I reinstall Avast so that is it all up to date and then disable the shields temporarily?

I'm really lost on what to do, and I'm so incredibly worried.

You can uninstall the Avast antivirus solution before the upgrade and reinstall the app after upgrading to Windows 10 version 1803. You can always delay the deployment of Windows 10 April 2018 Update.

Before installing Windows 10 Version 1803 I uninstalled Avast. After the installation the Windows refused to boot though I had not reinstalled Avast.

A backup of your system is still recommended but, that's up to you.

I would also disable any other programs that run in the background. Once that's done, Update to 1803.
Once that process has completed re-install the latest version of Avast.

The technique that Vlk described cannot work for me, because when I go to "Use another operating system" and I choose "Windows 10 on volume X", it opens Blue Screen of Death - every time. Before that, it opened the login section (I couldn't log in), but after few times restarting computer and choosing "Windows 10 on volume X", it started showing me that Blue Screen of Death, mentioned above. So how can I continue?

You may not be able to. You may need to rely on your backup and if you don't have one, you'll need to start from scratch.
If starting from scratch is your only option, then the first thing to do after a new install is to make a backup.

It seems very irresponsible that Microsoft doesn't ask customers to confirm that they have an up to date backup immediately before permitting a feature update to start.  Even a weekly backup could result in the loss of vital and irreplaceable information.

A disaster like this has been waiting to happen since Windows 10 started forcing updates that could only be avoided for a few hours.

I'm currently using an Android tablet, and reluctant to risk switching my Windows laptop on, even though I've switched Avast to passive mode.

For those who are trying to delay the installation, I would suggest going into the Windows folder and finding where the WU update files are stored when they've been downloaded, and deleting them.  Microsoft can probably only stop machines running Avast from starting the download.  When it's already downloaded, it might not require Microsoft's permission to start the update process.

I suggest that you create a new topic as this has nothing to do with this topic that you created.

How to solve error 1803

1.   Turn on computer
2.   At the blue screen, choose your keyboard layout language.
3.   Choose "Use another operating System".
4.   Choose the second option, "windows 10 on volume x Fig -3.
5.   Wait for the computer to boot to the desktop.
6.   Once the desktop attempts to load, close any error message.
7.   On a functioning Window Pc, go to www.microsoft.com/en-us/software-download/window10
8.   Click "Download tool now".  Disable any antivirus on the functional PC before proceeding to step #9
9.   Run the tool you downloaded, and follow the simple steps to create a windows 10 installlation USB stick.  This will erase any existing
      contents of your usb drive.  The only option you should check is if it is a 64-bit or a 32-bit.
10. On the problem computer, right-click any blank area on the task bar or where the task bar use to be on the bottom of the screen,
      then click "Task Manager".
11. Click "More Details" so that you can see the menu bar.
12. Click File
13. Click "Run new Task"
14. In the dialog box that appears check the box "Create this task with administrative privileges"
15. Click Browse
16. Navigate to your Usb Drive on left and select "setup.exe"
17. Run the file and follow the steps to "upgrade " Windows, change the option from "Check for and download updates" to "Not Right
      Now" and uncheck "help make this installation of windows better".  If you are asked what you want to keep make sure you tell it to
      keep everything.
18. Let the process run, which may take sometime.  Once completed, should be back to normal.  You may need to re-login in to Microsoft.
     
10.

I managed to get around this problem. I was able to launch a command prompt 8) by clicking the Ease-of-Access button (bottom right) on the sign-in screen. From there, I added a new administrator user with a highly-secure password:

Code: [Select]
net user /add NewUser password
net localgroup administrators NewUser /add

I was then able to log in as this user and follow the suggested steps.

I am a user of Avast Free. For the past few weeks I, along with many others, no doubt, have been distressed, bothered, concerned -- call it what you want -- about seeing the many posting issues here with the combination of Avast being installed and Windows 10 updating to 1803.

As I continued reading posts here day after day about the problems, I would get somewhat relieved when I'd see posts saying W10 (somehow) wouldn't try to install 1803 onto computers with Avast installed, members of Avast's team saying a patch was being installed automatically, users like Bob saying he came through the process ok, just to read other posts in the past day or two of people still experiencing problems.

Finally, my number came up, so to speak. Last evening a notification appeared on my computer that Windows wanted to install a new major update.

So, after saying a few prayers and swearing a bit, I took the plunge and let Windows do its thing. I didn't disable or remove Avast beforehand (yep, I have the latest build).

A half hour later, the job was done (I popped into the computer room a few times during that half hour (seemed like a lifetime) to see the percentage indicator go up).

And, my computer survived!  :D !!

I could breathe again...………….
