KB5037771 windows 11 bugs

Microsoft is working vigilantly on Windows 11, and it’s frequently addressing issues with new updates, but sometimes certain updates can bring new problems.

Many reported issues with the KB5037771 for Windows 11, and here are some of the problems that users have encountered.

KB5037771 update for Windows 11 causes issues with Firefox and other problems

This was first reported on the Microsoft Answers forum and one user reported that he was unable to download or install the update due to an installation error:

So ive tried updating this multiple times, ive restarted my pc, downloaded the standalone update, which didnt doanload it. i searched it up, and found nothing, this has been going on since around march now. it just says install error. i have a win 11 nvidia rtx 3070 16gb ram

This has been going on for a while, but that’s not the only problem as many had problems with Firefox according to Reddit.

Updated to KB5037771 today. Afterwards, Firefox had trouble opening after being closed due to a Firefox process refusing to close. Even restarting PC would not fix it.

The same user also encountered issues with sound following this update:

I also had a seemingly unrelated issue where my sound was randomly muted after restarting my PC. I then reinstalled my Nvidia driver since that’s what I use as my audio driver and both issues were fixed(at least so far).

It seems that the issue was caused by the Nvidia driver, but after reinstalling it, the issue was gone. While KB5037771 fixes VPN issues, it seems to have created other problems that can be easily addressed.

In other news, Release Preview update KB5037853 was released, and it brings various improvements, so if you’re on the Release Preview Channel, don’t miss it.
