The top, left panel of my Start menu is blank. If I select something from All Programs, right-click and select Pin to Start Menu (or Pin to Taskbar), the command is ignored. Changes in Start -> Properties -> Start Menu tab -> Customize are ignored.
The taskbar is locked. Any command to unlock it is ignored. I have tried right-click on the taskbar and clear Lock the taskbar; and right-click on Start -> Properties -> Taskbar tab.
Many other windows settings are not persisted, e.g. File options in Windows Explorer and the drop-down list in the Run dialogue.
My desktop had two drives, an SSD with Windows 7 Home Premium SP1 (C:) and an HDD with \Users and all my data (D:). The HDD failed and has been replaced (still D:). I have restored data from backups, but have lost all of the stuff in AppData.
As part of the recovery, I have gone back to a restore point before the HDD failed; and then had to install lots of Windows updates.
I have noticed event ID 1542 “Windows cannot load classes registry file DETAIL - The system cannot find the file specified.” at log-on time; with no details of which file is missing.
I have checked the permissions of D:\Users and subdirectories. Chkdsk and sfc –scannow both report no errors.
I had lots of trouble getting a user log-on that worked (event IDs 1505 and 1511). These errors ‘went away’ as I repetitively installed Windows updates and rebooted. During this time the file D:\Users\Default\ntuser.dat was created.
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\S-1-5-21-(long number) looks OK, it has the correct path in ProfileImagePath.
I read a site that suggested deleting the user account and recreating it. I’ve already done this while fighting earlier errors. There are also suggestions to check the file D:\Users(UserName)\AppData\Local\Microsoft\Windows\UsrClass.dat – I don’t have this file and there is no reference to UsrClass.dat in HKLM\SYSTEM\CurrentControlSet\Control\hivelist.
Can you please suggest what to change?
