I don't hold out much hope as Microsft has not found an answer yet. See their 119 page topic on this subject at http://answers.microsoft.com/en-us/windows/forum/windows_10-start/critical-error-start-menu-and-cortana-arent/5256ebee-2c77-4003-87be-1597ab10cb4d?page=1
Windows 10 Pro recently upgraded from Windows 7 Pro. User is a domain user authenticating through Windows Server 2012 R2.
Recently began seeing this error pop up...
CRITICAL ERROR: Your start menu isn't working properly. We'll try and fix it next time you sign in. [Button to Sign Out Now]
Signing out multiple (more than 10) times fixed the problem yesterday, but today so far numerous sign outs, re-starts and even a Safe Mode boot as suggested by Microsoft has not resolved it.
If I log in as a different domain user, or a local account, the problem does not exist so it's obviously an issue with the user specific Start Menu settings. Does anyone know if these setting exist in a file, or are they buried in the registry?
Thanks in advance.
