You can check the registry key as described here https://support.microsoft.com/en-us/help/4072699/january-3-2018-windows-security-updates-and-antivirus-software

Even if the registry key is present, you may not be offered the update. Don't know if that's caused by Avast or MS, but you can get it from the Microsoft Update Catalog here http://www.catalog.update.microsoft.com/Search.aspx?q=KB4056892

Here in Windows 10 1709 the key in de register is there and Ok.
Avast 7.9.2322 Free just updated to 7.9.3761.278.
But I still do not get KB4056892.
Also running Windows update troubleshooter did not help.
IntelSA00086DetectTool1.0.0.152 tells me I am still vulnerable !!
Do I have to wait for the next avast update ?

We can't see the registry key in my company.
We use Endpoint Protection Suite together with Small Office Administration.
Your computer with SOA uses a proxy to connect to the Internet. Updates are delivered to clients only from mirror (SOA). Updating from the Internet is prohibited.

SOA version: 1.3.3.112
Database version: 1450
Mirror or Client version: 8.0.1609
Virus Definitions Version: 180111-8

Version of file AvastEmUpdate.exe is still 10.2.1609.588 and does not change. Virus definitions have changed when I updated them over SOA, but not the program or its parts (such as AvastEmUpdate.exe).


We also use a computer where a standalone version of Avast Endpoint Protection Suite is installed. Registry changes are performed correctly after the update.
File AvastEmUpdate.exe was changed 5.1.2018 (current version 17.9.3761.0). Older version (10.2.1609.588) was backuped and saved as AvastEmUpdate.exe.bak.9913124109445268958.
This computer doesn't use a proxy to connect to the Internet.

Apologies for this newbie post but I'm a little lost as to which registry key to look for. I have Avast Free 17.9.2322 (build 17.9.3761.278). My system is Windows 10 (1709) and I have updated with the 2018-01 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4056892).

You have posted in the Avast for Business forum, it should be in the Avast Free Antivirus / Pro Antivirus / Internet Security/ Premier forum.

For speed the key is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\QualityCompat however if you have been able to install KB4056892 you must have had the key.  Also see https://forum.avast.com/index.php?topic=212691.0.

If you have any further questions please start your own new topic in the forum link that I gave.

Yesterday, we issued a patch for the machines behind a SOA mirror without the registry keys. It is downloaded together with virus definitions, and it is applied automatically. To download it immediately run Update server definitions job from the SOA web interface.

Avast Endpoin protection ver 8.0.1609  vir.db. 180129-4
Avast AEA ver 8.0.405

The key in the registry is fixed
BUT! clients of the WSUS do not see the update KB4056891. When I deleted the avast on the test PC. He immediately update on the WSUS began to download and install KB4056891.
Explain the reason? You write that the product Avast Endpoin protection 8 is compatible

Dear fordiegolg,
welcome to the club, you're absolutely right that there seems to be a severe bug in this version (8.x and AEA).
We've already had the same problem like you with the mirror which should be fixed now i believe.
And we still have the same problem that no system can be patched anymore due to Microsoft's Meltdown requirements and
its registry key AND Avast.
Beside WSUS Online we're using the offline wsusscn2.cab in 3rd party applications or direct api calls with WUA, the online WSUS version is working for some cases but the offline one for absolutely NO system.
And you're right it's definitely the Avast scanner, registry keys are ok, you can disable the services and disable feature of the realtime scanner, nothing is working. Only the old non-flagged patches were recognized and installed.
Because Avast's business support is sadly blazing with abstraction since the merge with AVG we've opened a case at Microsoft Premier to probably narrow it down more in detail. Nevertheless you're right, if uninstalling Avast all is working without any problems - also for testing with other av vendors. Btw. we're still using it on about 1500 servers. Still waiting on the final results of the L2/L3 engineers of Microsoft support. Will get them probably today or at monday... (btw. all server operating systems are affected, not only the client versions..)
