Windows 10 Version 1909 Nov Upgrade Faces Security Tools Blockage 

Windows 10 Version 1909 Nov Upgrade Faces Security Tools Blockage 

Windows users are once again facing compatibility issues and this time the issue is with the third-party antivirus tools. According to media reports the software major, Microsoft has implemented compatibility upgrade blocks on Windows 10 devices using Avast, AVG, and Qualcomm drivers. 

The action from Microsoft might stop Avast and AVG users from upgrading their Windows 10 operating system from 1903 to 1909 due to compatibility issues, the Techdows reported citing Microsoft. 

Announcing on Monday the company said, “Microsoft and Avast have identified compatibility issues with some versions of Avast antivirus and AVG antivirus. Any application from Avast or AVG that contains antivirus version 19.5.4444.567 or earlier is affected.” 

“To safeguard your upgrade experience, we have applied a hold on devices with affected Avast and AVG Antivirus from being offered or installing Windows 10, version 1903 or Windows 10, version 1909, until the application is updated,” the company said further. 

In an advisory tone, the software major asked Windows 10 users not to manually update using the “Update now” button or the Media Creation Tool until the antivirus companies don’t upgrade their software. 

Meanwhile, antivirus like Avast and AVG asked users to upgrade their software to version 19.8 to resolve the Windows 10 upgrade computability issue. 

Making the announcement Avast said on its website, “As of November 2019, Avast Antivirus program versions 19.5 or lower are no longer compatible with the Windows 10, version 1903 (the May 2019 Update). Before your PC can update to this Windows 10 version, a setup dialog displays the applications that need your attention first.” 

In simple words, you have to upgrade your antivirus to permit Windows 10 upgrade.

That is not all; your antivirus upgrade to 19.8 might not automatically remove the upgrade block. It might take some time, as the company normally waits for a few days before lifting the block. 

Earlier this month, Microsoft released the much-anticipated upgrade for the Windows 10 version 1909. Making the announcement John Cable, Director of Program Management, Windows Servicing and Delivery had said that the version 1909 and earlier version 1903 will be serviced by the same patch, meaning it will be easier, more efficient, and more secure for everyone.

If you are using Qualcomm WiFi adapter you might face upgrade block due to the same compatibility issue. A warning message will pop-up saying, “your PC has a driver that isn’t ready for this version of Windows 10. A new version is available please go to to learn more.”

So, it is “wait and watch” for you until Microsoft removes the block.
