Title: Windows 10 Start & Cortana critical error issue?
Post by: martlea on August 06, 2015, 01:15:54 PM
This was reported by a user on Windows Central. "Do those dealing with this problem have avast antivirus installed? If so, I believe that is what is causing the 'critical error'. I uninstalled the software and upon reboot my start button and cortana were working perfectly again."
If this is correct then Avast will need updates soon. If not an Avast issue then Windows Central need to be informed.

Repair Avast:
1. Control Panel -> Add/Remove programs -> Avast
2. Click on 'Repair'.
3. Follow instructions.
4. Reboot.

I'm having this problem as well, start and some task bar icons don't work.

Windows defender is greyed out.

Also can't find avast in control panel/programs to carry out a repair or uninstall n re-install.

Also Avast updates are hanging. I've also sent 2 notices via the app regarding this issue with no response

I had this problem and also, even if I don't get the critical error, the whole Windows 10 UI freezes. I have to use the task manager to restart the explorer.exe and than bang!! Same thing happens... Sometimes I get the Start & Cortana Critical Error if I wait long enough.

I had to switch to another antivirus because of this.

Fighting this issue for 3 days now (and I'm an experienced break/fix tech)

You can try system restore, but in order to do that your going to have to completely uninstall avast! and reboot first (make sure you reboot). For whatever reason, even with the SDM turned off, system restore isn't able to modify the definitions folder for avast! and will fail.

My first system restore has brought back Cortana, but I still don't have a start menu.

As far a rebooting to fix..... I'm sorry to say that you are only at the beginning of the problem my friend. It started out like that for me too. Reboot/Logout would fix it every time. Then, a few days later..... start & cortana are both completely unresponsive.

When I figure it out, I'll post

I had to reboot my system several times to get this cleared up.
Sorry, I don't buy into the thinking it's an avast issue. I do believe in
making regular system backups. At least twice a month preferably once a week.
An aggressive backup program is a must. There are several backup utilities available,
personally I use AOMEI Backupper Free. To be honest I'm making a backup right now.

It seems to me the culprit is Cortana. IMHO Cortana is something that is totally not necessary and Microsoft should dump it.
Title: Re: Windows 10 Start & Cortana critical error issue?
Post by: malone.m on September 03, 2015, 10:25:37 AM
The main problem might be that the entire so called "modern apps" environment in some  cases can't be properly initialized or crashes. I would say that errors regarding Cortana and Start menu are nothing but "side effect".

I don't wish to argue with anybody who is responsible about this issue, but:
- fact - with the avast av I have the issue, w\o - haven't!
- it isn't interesting how or why, as user (in case of Avast & Microsoft) what is important for me is WORKING SYSTEM!

Frankly, the MS isn't the big losing of this :(
May be MS is responsible, there is such possibility for sure!

I wish successful resolution of this matter!

I also just installed Avast Business and immediately had this Start Menu Critical Error failure appear .
I can reboot and it will work for a while but next reboot it fails again.

Note: Please don't reply or give opinion if you are NOT running Windows 10. it's not helpful.

many reports of this found in Google. the solution is usually removing Avast. anyone found a different specific fix to make Avast stable on Win 10?

Unfortunately it's "definitely" not "usually"!
For now I don't know any kind of "work-around". And more, the time spending for pointless searching
is much more expensive than the particular av-software :(
There other AVs working fine with w10! In yours case "Avast Business" it means some money :(
But as i said above, time & security are most important, so find another way!
Obviously AVAST trying to prove that the cause is in MS (it's their right & business:)

I'm having the same issue. It started with the free version of Avast!. Now that I've purchased the Avast! Internet Security, it will give me the Critical Error each time. If I remove Avast!, then it works fine.

I was an Win 8 -> Win 8.1 -> Win 10 upgrade process.

This is a Win10 error.

Create a task and run as admin to reboot in safe mode.

Then when its in safemode untick 'boot to safe mode'.. then reboot normally and the error should be gone.

Win10 seems to have a lot of little bugs like this.

You think its bad for you?  I can't even run Cortana here,  as it is not enabled in my country, and yet Cortana still crashes many crucial parts of my O/S and/or desktop.  When I am not using it.  WTF and stuff.

I get the same error "start menu and Cortana cannot start" from time to time.

Some may blame 3rd party Antivirus for causing the trouble. I wouldn't be so bold to claim what was NOT proven but, nonetheless, it gave me the clue.

Solution:
1) Start your computer as usual
2) Go have dinner, a jog, a shower... stay away from the computer for as long as you could afford. Allow whatever malicious tasks running in the background to complete.  :-\
3) Login, preferably, when the busy hard-disk LED stops blinking

The actual cure as found on the Microsoft help forum states to simply boot into Safe Mode with Networking
Once in Safe Mode, reboot into Regular Mode and the problem will be history. :)

This was an issue in early releases, not anymore...
Title: Re: Windows 10 Start & Cortana critical error issue?
Post by: HappyAvastUser on November 28, 2015, 05:19:57 PM
It's still a problem with everything up to date.  Everything on my computer is updated to the most recent versions...Windows 10 and the newest Avast Internet Security.  I experienced the "Start/Cortana" critical error this morning.  This is the third time this error has happened on this computer since the upgrade to Windows 10 a couple of months ago. 

Looking at the Microsoft boards, I don't think this is an Avast! issue, but it happens to Avast! users as well a  lot of others.  I probably jumped the gun upgrading the operating system.  I broke my rule of waiting until the 1st service patch, but as annoying as it is, I can deal with it.

As others have said, the Safe Mode restart method does not always work.  I've ended up just trying different things until I find something that actually does work for the current problem.

Like others, I am hoping a patch is found soon to put the problem "in the rear view mirror".

Hi malone.m,
thanks for reporting. Can you, please, post a screenshot of the issue (easily done with WIN+PrtScreen shortcut when a modal dialog/band is displayed). To us it appears that MS has fixed the crashing of the sihost.exe process in such a way, that it no longer displayes the mentioned critical error message, just restarts.

I'm also having this issue. This is the second time. I uninstalled Avast the first time and it was fine. Windows 10 is up to date. I even have Cortana and all of the location, privacy stuff disabled. I decided to take another shot and download Avast again a couple months later. And now I'm having the issue again. I can't even uninstall Avast because it freezes on the first part regarding "aswNdisFit." I'm not sure what to do. I have school stuff on here to do and am freaking out a bit. At this point, I just want Avast gone so I can use my computer again.

Freaking out for a good reason?:  Maybe your school stuff is not backed up yet?  That would be the first thing I suggest doing and then use this tool to completely remove avast and any other a/v programs previously installed prior:  https://www.avast.com/uninstall-utility (https://www.avast.com/uninstall-utility)

The link you posted in your reply refers to versions prior to TH2 (1511). I personally haven't come across this problem for quite some time.
The boot to Safe Mode with Networking and then a reboot into regular mode always worked in the original 10240 version of Windows 10.

You may need to use the Media Creation Tool offered by Microsoft to create either a DVD or USB drive and update to 1511 with that created media.

Yes I created the ISOs 2 weeks ago.

The issue still remains that there is no guarantee that 1511 fixes this issue once and for all. Only after running a system for a couple months will we be more sure of that. This is as I mention other solutions that were thought to fix the issue at the time sometimes become temporary. The only sure way as I mentioned is to revert back as I will probably do in this case, to Windows 8.1. That is because I have spent countless hours on fixing now 2 start menu issues and the lack of a definitive answer from Microsoft is causing the computer owner to regret upgrading to Windows 10.

That was most likely version 10240. Currently you would be creating an ISO for 10276 (1115)

Nope it was for TH2 I have created ISOs for and verified that iti is indeed 1511 in the ISOs. I pulled down the ISOs via MCT as soon as Microsoft released them. This was before they pulled them temporarily due to a bug affecting small number of end users regarding privacy settings not being maintained properly during the upgrade install. My laptop also was upgraded at the same time via Windows update to 1511 on Nov 14th before MS briefly pulled the update.

Post by: pcguy on December 01, 2015, 11:52:33 PM
I totally removed Avast and have yet to install 1511.

I will give the computer owner several options. Upgrade to 1511 which I can not guarantee will fix this issue permanently as long term testing will prove that. Only reverting back via a clean install of Windows 8.1 is a guranteed fix for the menu issue.  I have spent probably 10 hours on trying to fix these Windows10 issues and and several trips to their location. To put it mildly the computer's owner is getting fed up with Windows10. The silence from Microsoft wrt to a definitive answer is deafening.

So the Cortana and Start Menu problem you describe is on a system that doesn't have Avast installed ???

It did have Avast installed while the owner upgraded from Windows 8.1 to Windows10 and Avast remained installed when the start menu failed to open at all requiring creating a new account and migration of its data. Avast continued to be on the computer when the Cortanna and failure of the start menu under the new account a week later. Since antivirus apps operate at low level of the o/s and since Avast was updated application wise when the first screw up of the start menu, Avast was uninstalled in an attempt to eliminate it as the source of the problem. Since Microsoft has been silent on this particular error we the end users have to try to fix the problem!

We are mixing apples and oranges. The Start Menu and Cortana problem is not an Avast problem but a problem with the earlier versions of Windows 10.
You'll find many discussions and suggestions regarding this problem on various Microsoft forums. The later builds of Windows 10 including the 1115 release seem to have
fixed that problem. The fix isn't up to the user but the manufacturer.
In windows 8.1 you didn't have this problem since there was no Start Menu or Cortana in Windows 8.1.

Yes, I never got this problem with 1511. It was a common problem on my PC too since Windows 10 with or without avast on it.

People have applied "fixes" to this problem and for a while those fixes seem to be working and then wham this issue cam back again a couple of weeks later. Since 1511 has only been out for 2 weeks. There is nothing to say that this problem will reoccur tomorrow or next week.

Only further long term use of 1511 will definitely prove whether in fact it solves this issue. These are the worse type of problems to solve as there are no official word from Microsoft regarding this.

I updated my Dell Xps One very soon as W10 was released. Very positive experience, with no troubles at all.
After long time of perfect operation, yesterday evening I received an update of Avast Antivirus. Since that moment, after reboot, the critical error appeared and does not want to disappear.
Easy, you could say, try to uninstall Avast. Not so easy, boys, because uninistall says that it is impossible to remove avast because a reboot is pending.... but the reboot cannot be completed because the critical error clearly does not allow its completion.... a closed loop in which I am completely stuck!
Any suggestion? Thank you very much
Addition:
1) F8 key is ignored (neither enter safe mode)
2) startup and shutdown are considerably longer to perform
3) updated to 1511
(suggestion: use a more readable verification system, it is very hard to decode)

IMPORTANT
I amend my mistake due to the fact that I manage many PCs. The PC I was talking about had not, reply NOT, the 1511 updtate.
So forgive me and forget my post that is not significant at sthis stage.

So if all else fails, update that system to Windows 10 v1511 and your problem should be solved.
If not, let us know. :)

I've been having this problem at least once every two months. I'm 100% sure it's related to Avast. I use Avast premier (using the latest version currently). Every time I have this issue, I reinstall Avast, and it fixes the problem, a while later...It reappears.

However, on my other systems where I'm not running Avast, no problems. I admit, this does happen to certain users who don't use Avast. But in my case, and probably a lot of others here, it actually seems to be Avast causing the problems. I'm not sure why other non Avast customers get it, that's probably related to some other software they're using.
Can someone look into this and sort it out? It almost always happens when Avast has a update to the actual software, definitions is usually fine. It really sucks that Windows 10 has been out for so long and Avast is still causing problems, looking at CCleaner. Avast isn't doing a nice job messing up the registry either.

I used to be a big fan before this problem screw me up. My windows 10 with avast free screw up my taskbar and totally disable the Start key, I thought it was my problem then I restore Windows to default setting then it was fine for like 1 month, then same thing happened again. I google and found out it could be Windows problem, but I tried all solution people talked about but none of those worked at all. Finally I saw someone said it could be Avast problem, I uninstall Avast then instantly the taskbar works completely fine!

Stop saying it is Windows problem! Uninstall Avast will solve this problem, then it is not Windows problem! This is just simple "windows 10 is not compatible with Avast"! How do some of you guys saying it is Windows "bug"? You expect Windows to change code to so Avast works? It must be Avast changes code to work in Windows! Just uninstall Avast then instantly solve the problem then it is 100% Avast problem!

I install another free antivirus problem doesn't have this problem at all Windows 10 works completely fine, you say this is Windows bug? Yes Windows 10 has similar problem for some people but it is totally another issue as I said I tried all those solution and it would not work when it is Avast screws up the taskbar.

Simple answer: uninstall Avast solves this problem and it is the only solution.

I have to agree 100% with @j2ee. I'd say it isn't windows 10 fully compatible, I had to either disable/unistall avast so that my clean install of windows 10 works properly and apps no longer drag/freeze. In conversation with a friend (both being avast users for a long time) he also told me that he had done the same think, the solution he found was to uninstall avast. It looks like you guys are ignoring the facts here, I like avast that's why i'm leaving the feedback.

I didn't want to uninstall avast and install AVG because Avast has much better performance, but as you said there is no other way other than uninstall Avast then I can just do that in order to get back my taskbar, start button working. I really don't know how to use my computer without the start button. I don't mind Avast screw up something of windows that I don't use, but everyone uses start button :o

If you care to read this topic and other topics on this you will see it advised to boot into safe mode and then reboot into normal mode and that is supposed to resolve it. For many that has been sufficient to resolve it, I don't use windows 10 so I have no personal experience of it, just what I see reported in the forums.

You are still putting the blame on the wrong product.
Your AV isn't causing it, it's the operating System. This happens to computers that have never used anything except Defender.

This problem didn't happen right after I install Avast, it happened like 1 to 2 months after I using Avast in Windows, and two times not one time. Many people above in this post already said the only solution was to uninstall Avast, anything you guys recommended either not working or only temporary working then the problem comes back again after only days.

Also, other popular antivirus programs don't have problem like this at all, it is just Avast with windows 10, then it is very simple logic that it is Avast not really compatible with Windows 10. Microsoft would not change code of windows (I would not say this is bug) to let Avast works in Windows 10, Avast needs to change code of the antivirus program to work in Windows 10.

For what it's worth, I had huge problems with Avast Free under Windows 10 as initially released and ended up uninstalling it. Following the November 2015 Windows 10 upgrade, I gave Avast another go. There were sporadic problems but they increasingly vanished with subsequent Windows 10 cumulative updates and now I can honestly say that Avast has caused no problems at all for the last few months.

I hesitate to say this among so many experts, but I've been really surprised at the number of Windows 10 computers I see, especially new ones, that don't have the November 2015 upgrade. Perhaps worth checking that Windows 10 is Version 1511 (OS Build 10586.164)?

You are very funny
I searched and no single one person mentioned the word "Avast" in that Microsoft post. Even the outcome is similar with taskbar problem, it is totally different cause.

Comparing these two:
1. People report problem in that post in Microsoft doesn't use Avast, 0% ok? There is no Avast to uninstall to solve problem.
2. People in Avast report having taskbar problem 100% use Avast ok? You know what? Uninstall Avast 100% solve the problem, everyone over here who said uninstall Avast solves the problem!

It is totally two different cause even though the outcome is similar! OK, so car crash would let a person die, then can I say everyone die must be because of car crash but not something else like cancer? Microsoft post is like car crash then die but Avast forum case is cancer then die, yes both die (taskbar die) but because of totally different reason.

From one of the multitude of threads on this :
Quote
Since last Wednesday I have not been able to get most of the new Win 10 features to work. From Start to Cortana to Edge to Email to the Windows Store. They all just flash for a second, then they are gone. Except the Start menu, of course. It only gives me a critical error message and then makes me restart.

I did once, in the middle of the night, get them all to work. I had just gotten a pop up from Windows saying I was low on memory, I clicked on it, the screen went dark, then suddenly my messages from the activity center started showing up. Then I tried all the Win 10 things, and they all worked. Of course I had to reboot, and by then nothing worked.

I did try a system restore. I found a restore point just before the last cumulative updates started. It ran for two hours, seemed to be progressing, then at the end it told me it was not able to restore due to an error (0x800703f1).

I don't have Avast, but I did delete my Norton Security. I had no idea that the new Windows Defender worked so well. After reboot the action center (or whatever it is called) was filled with message from Defender, and mail I had waiting. I could not get anything else to work. After a reboot, that stopped working too.

What exactly would be involved in reinstalling Win 10? It seemed to keep most of the files on my 8.1.1 laptop, but not as many on this PC which was running Win 7. Where do I even find the download again? I guess I thought, all along, that the next Windows update would fixed it. But I have run them all, and nothing seems to be getting better.

Is this just happening on 64-bit computers, because my 32-bit laptop is working just fine?

Thanks for any help you guys can give. I am totally lost and frustrated after a week of a system that only half works.

Base on what I read, I think he means he never even installed Avast, then it is another kind of cause which is very likely the Microsoft post kind but not the Avast cause kind.

Even when someone had never installed avast, it doesn't mean it is not the same cause.

I know for a fact that Avast is the cause of Cortana not working. I do computer repair for a living and none of your solutions work when Avast is installed on Windows 10, the only way I have found after hours of trying was to remove avast and just not use it on a Windows 10 system. I have had probably 20 fresh install Windows 10 systems with this problem all with Avast installed and the only solution was to remove Avast. So now instead of every computer that comes through my office getting a free copy of Avast they just use Windows Defender. Way to not own up and continue to loose customers. You can't tell me that when I have probably done 100+ Windows 10 systems since launch day and none of them have had this issues unless Avast was installed that its a Windows problem. If Avast is the only common denominator then that's probably the problem, no problems on any of my customers computer since I stopped installing Avast. I am truly disappointed with Avast for not owning up and fixing the issues with their software.

I've worked on a lot more computers that had never seen Avast and still had that problem. :)

That does not explain why if Avast is installed the problem happens and then when Avast is removed the problem goes away hence in this instance it is a problem with Avast. If you don't have Avast installed this is not a forum for you. Yes Windows 10 may have a issue with other programs as well relating to Cortana but it is up to programs to become Windows 10 Compatible not up to Microsoft to change their whole operating system because a company cant get their head out of where it doesn't shine.

I have never had that issue unless avast was installed, I'm gonna say that with 100+ windows 10 systems not having that problem under my belt since no longer using Avast it is a Avast problem. You can deny it all you want but it doesn't change the fact that I can take a 100% working order brand new Windows 10 system and break it by installing Avast.

Its not opinion its fact, if Avast is installed this will happen unless they have fixed the issue.

If its just opinion they explain why the problem goes away and never comes back once Avast is uninstalled? I could understand you saying its not avast if it was on one system but when I have over and over again had the issue on many freshly reloaded systems and the problem is resolved by removing Avast then it is a Avast problem. So many people here have said the only way they could fix the problem was by removing Avast and they continue to ignore the problem and say it is a windows problem. So go ahead they can continue to loose business because they are to stupid to fix their own problems. There is hundreds of accounts of this problem all over the internet and the permanent fix is to remove avast otherwise all other options are temporary fixes.

LOL that's the funniest thing I have seen all day. All the links provided either tell people to go into safe mode and back to normal mode which if you read the comments and talk to the people who have tried it that's only a temporary fix and the problem comes back after a few restarts which then safe mode no longer works to fix the problem. The only other suggestion in all those links was to remove the antivirus causing the problem. 

Secondly Essexboy just because you have Avast and Windows 10 and don't have the issue does not mean that Avast isn't the culprit. Do you actually work on computers? Because saying "I have Avast and Windows 10 and don't have the problem" it about the stupidest thing I have herd on a reason why Avast is not the problem. Anyone who actually works on computers knows that you could have two identical computers and both have the same issue and what fixed the problem with one wont on the other. You can try to defend Avast all you want but it is their problem they need to fix.

I think you've made enough posts on this topic. You are entitled to your opinion and it's been stated.
Continued nagging isn't going to strengthen you position.

I find it funny that none of you have actually had any experience with this problem yet you act like you know everything about the issue at hand. You have no use arguing with me either because I know I'm right and you obviously don't know. Do yourself a favor and actually research the problem I have spent countless hours doing so.

I commented here to give my experiences on the problem and to let people know if they don't want the issue to continue to uninstall Avast and the problem will go away. You guys decided to argue with me I will defend my factual findings till my fingers are bleeding and I can't type anymore. I know what I'm saying is true because I have done the research and experienced it first hand. Most of you who have lots of posts and are trying to explain to people how to fix things admit that you either don't use Windows 10 so you have no experience or you either have avast and have not had the problem or don't have avast and have the problem. So still no experience with why Avast would specifically cause the problem.

Maybe if you had done some more research you would have found that I have indeed experienced this problem and have posted on it profusely.
Again, your opinion has been posted and noted and so have those of others.
I haven't run into this problem again past Windows 10 build 1511. Both with and without Avast installed.
