Update KB5003173, released in Patch Tuesday May 2021, reportedly causing problems for some users of the Windows 10.
One of them is a nasty Microsoft Edge compatibility bug that stops it from working Windows Update, which means that updates cannot be installed and it resets automatically.
KB5003173 is the cumulative update for the latest version of Windows 10 (20H2 version, released in October 2020) and the 2004 version (released in May 2020).
During the implementation of Patch Tuesday this month, many users noticed that the installation did not proceed with a mysterious message "0x800f0922" and Windows started the automatic reset.
Based reports by Reddit, error 0x800f0922 appears to be hitting devices on which Microsoft Edge (Chromium) has been removed manually.
When you install KB5003173, it also attempts to install the Chromium Edge. However, the installation fails when it detects an empty Edge folder on the system disk (C:\Program Files (x86)\Microsoft\Edge\).
This can happen if the Microsoft Edge folder was not removed correctly.
How To Fix Error 0x800f0922
There are two solutions: Manually reinstall Microsoft Edge from the Microsoft Web site and try again to get the cumulative update. Or just remove the Edge folder from the path C: \ Program Files (x86) \ Microsoft \.
This will allow the cumulative update to proceed.
Unfortunately, there are cases where the installation of the update fails with different messages each time and the above solution does not work.
Failure to install the Windows 10 update is always accompanied by an error message and this code may differ. Some users have noticed that updates and installations reach 73% and then fail with a different error message.
If you are one of them, there is no known solution, but you can try to fix it functional system using it Media Creation Tool.
It is worth mentioning that KB5003173 installs security fixes in Windows 10 and fixes a CPU usage error.
