It looks like another bug with a Windows 10 update is causing misery for some users. People who go online complain that the Start menu is behaving erratically after installing the Windows 10 September 2020 update (also known as KB4571756 and KB4574727).
The Start menu is an important feature of Windows 10 that gives you quick access to installed applications. As a result, an update is reported to be causing problems.
It seems that the new Windows 10 update doesn’t just have to do with users’ Start menus, as some users have also experienced the dreaded Blue Screen of Death, problems logging into their PC, and other errors.

It could be that a change in Windows 10 KB4571756 that has made Windows 10 tablets and 2-in-1s work better is preventing users from opening the Start menu or Action Center.
While not being able to use the Start menu isn’t bad enough, you can’t log into a PC either. Windows 10 appears to log users out once they are logged in.
Then there is the Blue Screen of Death that comes up when Windows 10 crashes and becomes unresponsive. All a user can do is restart their computer and potentially lose any unsaved work.
It also appears that the temporary user profile error is back. This is a problem that has been cropping up an alarming number of times recently. If a user loads Windows 10 instead of logging into their own account, Windows 10 forces them into a temporary user profile, which means their settings, themes, and even data are not available.
It’s incredibly annoying, and Microsoft has promised to fix it in the past. So it’s disappointing to hear it could be back.
How to fix the problems
Until Microsoft comes up with an official solution to these issues, which is likely to come in the form of another Windows 10 update, the best way to fix these issues is to uninstall the problematic updates KB4571756 and KB4574727.

You can also try using a restore point to fix the problems. Simply select a restore point from a time before you installed the update. We also have a guide on how to use Windows 10’s System Restore feature as an aid.
We asked Microsoft to comment on these new issues. Hopefully the company will find a solution soon.
