For all of you that uninstalled avast and then managed to download the microsoft patch, did you reinstalled avast without issue afterwards? Another option I am thinking at would be to stop using avast and use another anti-virus…
I am a bit surprised that no one from avast is communicating on this issue…
The tool doesn’t support MS-systems below W7!
=Snake=
Still waiting for that registry key. Why am I not getting the micro-update? on windows 7 and using avast free.
Removed Avast on my newer Intel I7 based laptop, and did receive the update right after restart after Defender was activated, have not tried reinstalling Avast Free yet, but I might, as rest of the systems using Avast Free, Desktop did it manually with the windows catalog update way
don’t know why couldn’t get it from WIndows update with Avast installed, reg key was there, so makes no sense, Malwarebytes supposedly was up to date the program said
Hi,
if you have required registry value in QualityCompat key, then there is nothing more Avast can do, because Microsoft is controlling Windows update process, so please don’t panic if the update was not delivered yet. It was not delivered to my development PC (no AV installed) too, although I was trying to check for update manually multiple time.
I’ll wait and see what happens on patch Tuesday.
How do I obtain the key?
I have the registry key for Windows 7, but not Windows 10. I can think of three options.
Thoughts about how to proceed?
So would it be safe to reinstall Avast on machine I removed it from to obtain the update yesterday or should I wait til after Tuesday to do that?
I did item 1 above and the registry key has been created. I checked for updates and none were found. I suppose that I will wait for patch Tuesday and see if my machine catches any updates then.
I have Avast and MalwareBytes.
I am on the Fall CU Windows 10.
No install of the MS patch until I uninstalled Avast and replaced it with Avira. Instantly the patch download became available so there is clearly still an issue with Avast (BTW I had Free, but I followed a link from the Free forum over here as it appears that prem customers are also suffering)
i have the key in registry
Key=“HKEY_LOCAL_MACHINE” Subkey=“SOFTWARE\Microsoft\Windows\CurrentVersion\QualityCompat” Value=“cadca5fe-87d3-4b96-b7fb-a231484277cc” Type="REG_DWORD”
BUT, its data is set to zero… does the data of the key value matter in any way? should it be set to 1? should i mess with it?
my Avast is updated but windows 10 x64 1709 still won’t detect and offer to install the update… maybe the data of the key is the problem?
tested on 2 computers:
-notebook with I5-6200U cpu
-desktop with I5-3570 cpu
Further information, I checked my registry and do not have the key I’m supposed to have. Please advise. Peter
CORRECTION: I was looking in the wrong place in the registry. I do have the required key. However, MS update isn’t providing the patch. Should I wait until Tuesday or manually download and install the patch now?
Right after uninstalling Avast and checking for updates.
No I didn’t try passive mode. I can try that on my other PC’s running Avast that still aren’t getting the update. And for those that have asked, I have not yet re-installed Avast on the computers I uninstalled the program from.
We know Microsoft is looking for antivirus programs before attempting to even download the patch. Many others have reported having an issue with other AV programs. I simply removed the roadblock as I saw it. We also know that Microsoft has made this patch a priority, therefore users should not expect to wait for the patch as if they are in a queue. If you are running Win10, the patch is available NOW. If you are running any version previous to Win10 (8.1, 8, 7), that patch will be coming on Patch Tuesday (Jan 9, 2018).
I will update this message after trying passive mode on the other PC’s running Avast.
UPDATE: As suggested, I configured Avast for Passive Mode on the PC’s with Avast still running on them. In both cases, the exact same result occurred: After the obligatory reboot to enable the changes to Avast, I went to Settings, then Update & Security, and clicked on the Check for Update button. Windows Update showed an update was available (it is the correct one) and downloaded the file. It then stated it was starting the installation and STOPPED before the update was complete. “Your device is up to date. Last checked: Today 7:10 PM”. Further investigation shows that the patch was NOT installed.
In conclusion, Passive Mode does not resolve the problem, at least on my PC’s. It appears that Microsoft sees that an antivirus is not actively monitoring the system and downloads the patch. But in the process of installing it, maybe it finds the presence of an AV program and fails so it doesn’t potentially brick the system. This is just conjecture on my part based on research I’ve done on the problem today. YMMV.
Hello,
I installed a fresh 1709 build today, installed avast and did all windows updates however noticed KB4056892 didnt show up at all, even after updating my Avast to lastest versions etc.
I then decided to download and manually install the KB4056892 patch from windows catalog, I did not check my qualitycompat reg thing prior to doing this, the patch installed without issue.
Can somebody please let me know if I’ve done the correct procedure? thanks
i have the registry setting but did not receive the update from MS… decided to download it manually from the catalog and discovered there are actually TWO updates… one of them (KB4058702) updates the updating system itself and should be installed before the other - Servicing stack update for Windows 10 Version 1709: January 3, 2018
https://www.catalog.update.microsoft.com/Search.aspx?q=1709%202018%20x64%2010
i’m currently installing 2018-01 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4056892)
will come back and edit this after it finishes correctly
edit: back after reboot, no BSODs so far and avast is running, even ran a smart scan

No update with Avast installed. Removed Avast to change from Beta to Regular version.
A few minutes after the reboot, I saw this

Rebooted and the update had been applied

This needs to be addressed. I’ve already posted this on the developers channel
The support of Windows has told me that it will be progressively implemented throughout these days, I hope that is so. It’s already on the way, with Avast Premiere two and a half weeks ago and you do not have to update it. I hope that what Windows has told me is true.
Here in Windows 10 the key in de register was missing.
After Avast repair (+reboot) the key appeared.
But I still did not get KB4056892.
Also running Windows update troubleshooter did not help.
IntelSA00086DetectTool say I am vulnerable !!
Any ideas ?
Do I wait till next Tuesday ?
