My local user profile on Windows 10 Pro version 1607.14393.321 has been having the following problems since at least 2016/10/17 when update "Update for Windows 10 Version 1607 for x64-based Systems (KB3199209)" was installed:
- Start Menu won't open. This was permanently resolved by running file "startmenu.diagcab" which repaired a corrupted tile database and one other thing.
- Search won't work. This was temporarily resolved by toggling from the Cortana icon to the search box but that no longer works and this hasn't been resolved by anything else (checking Windows services, repairing App components, SFC, DISM, etc).
- Configuration of Explorer (window size, folder ordering) and System Tray (icon ordering) but not Taskbar is lost on restart of explorer.exe or the PC. Running file "Reset_Notification_Area_Icons_Cache.bat" as my user or as administrator doesn't resolve the problem and reports the following:
The Explorer process must be killed to reset the Notification Area Icons Cache.
Please SAVE ALL OPEN WORK before continuing
Press any key to continue . . .
