Patch Tuesday updates should typically address Windows 10 security concerns and a host of quality issues, including bugs caused by previous upgrades. Update KB4540673 fixes many such problems, but it also introduces numerous unexpected PC complications, according to multiple user complaints posted on Reddit.

Update causes the Blue Screen of Death

When Microsoft rolled out the KB4540673 update, it only acknowledged a single issue. Using Windows Server containers with the March 10, 2020 patch could cause problems with win 32-bit apps and processes, the company warned.

Emerging user reports suggest that the update may also cause your onboard graphics to malfunction. In a Windows Subreddit post, one user claimed that updating their OS resulted in the BSoD error.

I installed the new update (everything was working fine moments earlier), and now using onboard causes a BSoD.

The update did not break the user’s graphics processing unit (GPU), though.

Flickering screen

Another user posted a video to the Windows 10 Subreddit showing a flickering PC screen after installing the latest Windows 10 update.

Can somebody help me after I installed the new Windows 10 update this keeps happening and I can’t log in to my pc anymore.

The user has since marked the issue as solved. The bug had locked them out of their system, and it is not clear if the fix came from reinstalling Windows 10 via USB instead.

A graphics driver problem can cause you such frustrations after upgrading your OS, especially if you are unable to log into your PC to update it.

Update stalling

For some users, the update is taking ages to install. It did not go beyond 1%, one user claimed.

Another reported the error code 0x800f0922 after attempting to update.

I keep getting an error whenever trying to install this update, so I guess I’ll just skip this one out.

The KB4540673 security patch is not necessarily the cause of the 0x800f0922 bug, and there are several ways you can try to fix it at home.

Until Microsoft finds a way to deliver perfect OS fixes and improvements, you can always count on Windows 10 updates to bring a mixed bag of goodies and some not-so-pleasant surprises.

Why not back up since you do not know when the next upgrade bug may hit your PC? It is a better contingency plan than not attempting to install critical security patches at all.
