Problem:  

One user can not use Start Menu and settings. So I created a test account, the test account has no problem use stat menu and settings

Solutions:

If a new created user account has no problem to use the start menu and settings, that tells me that the Windows system might be  OK. The “bad” user account might have a corrupted profile.

1: Log in as the new created user.

(You need to create a second Admin account to do this.) You need to enable “show hidden files….” and disable “Hide protected operating system files”

2: Go to c:\users\bad-user name\appdata\local\Microsoft\Windows find UsrClass.dat  rename it UsrClass-old.dat

3: Restart the computer

The problem should be resolved.

Press Windows key + R
Type: control userpasswords2
Hit Enter or click OK
