Start don't work, and Computer is 5 times slower. We used, sfc/scannow a bunch of times with a restate each time but didn't help at all. We were thinking about uninstalling windows 10 back to Windows 7. The computer ran windows 10 for about 2 weeks just fine and then this happened. Can anyone help?
If I understand you correctly, you are not alone.
Start menu button and search stopped opening/working Win 10
Black screen after login
Start Menu Not Opening - Windows 10 64 bits
Had this bullshit on every win 10 installation (1 upgrade first, then 3 clean installs) and every single one of them got nuked by this bug after around 2-3 weeks. It has something to do with user corruption afaik, and nothing I have tried fixed it at all. Seems like all we can do is wait for MS to fix, but there are some fixes you might try in those threads, hopefully they do more for you than they did for me. My final solution was going back to win 7, and everything is golden again for some weeks now. Good riddance to this OS until extreme bugs like this get fixed.
