Microsoft users with older versions of Avast or AVG Antivirus won’t be able to upgrade their devices to Windows 10 1903 or Windows 10 1909, following the compatibility hold issued by Microsoft.
In an updated document listing the known issues and the status of the rollout for Windows 10, the tech giant explained:
“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,” it added.
According to the post, among the affected devices include Windows 10, version 1909 and Windows 10, version 1903. When attempting to install the May 2019 Update and the November 2019 Update., Windows 10 Setup will recommend uninstalling the Avast or AVG app as “it isn’t compatible with Windows 10.”
After downloading and installing an updated version of Avast or AVG application, only then can users proceed to update their devices to Windows 10, version 1903 or Windows 10, version 1909.
“We recommend that you do not attempt to manually update using the Update now button or the Media Creation Tool until a new version of your Avast or AVG application has been installed and the Windows 10, version 1903 or Windows 10, version 1909 feature update has been automatically offered to you,” Microsoft noted.
Aside from the older version of AVG and Avast, PCs that are running old driver versions of Qualcomm WIFI adapters will also be denied from installing Windows 10 1909.
According to a report from Techdows, when attempting to get the update, a message will pop out saying: “your PC has a driver that isn’t ready for this version of Windows 10. A new version is available please go to aka.ms/qcamain10_4_0_2 to learn more.”
Similar to the case of AVG and Avast, Microsoft confirmed it has identified compatibility issues with some driver versions for certain Qualcomm Wi-Fi adapters.
“To safeguard your upgrade experience, we have applied a hold on devices with affected Qualcomm driver from being offered Windows 10, version 1809, Windows 10, version 1903, or Windows 10, version 1909, until the updated driver is installed,” the post added.
