I updated my Windows 10 laptop to Windows 11 Beta Insider Build today and downgraded back to Windows 10 after using it for a couple hours. After downgrading from Windows 11, Windows seems to have corrupted or something.
After downgrading I deleted all the files in C:\Windows\SoftwareDistribution\Download. Then I uninstalled some updates that were updated during the Win 11 upgrade. And I also rolled back my Intel Display adapter to the previous version (because Windows downloads a new one for Win 11 support I guess).
The problems are:
When I open the Task Manager and selected the Performance tab, it doesn't show the WiFi graph. After a restart it was back to normal.
Then I installed Win Terminal from the store. When I open it from the start menu it doesn't open the Terminal app, but it redirects to MS Store instead. I tried the same thing with another app, but the results were the same.
I tried resetting the MS Store cache and re-registering it, but neither of those two solutions worked. To solve all these issues I thought of resetting Windows, but later I didn't do it, because I don't want to go through the hassle of reinstalling every single piece of software I had.
