I am working in a school were laptops are shared between students, and up to 60 kids can use the same laptop in a week's time. The first time we encountered any problems with this was when one class in particular came in with two students receiving an error:
At first, clearing out the user profiles (except the local Administrator, current logged in admin, and the Public profiles) in Regedit, and the C:\Users solved the issue.
After it kept reoccurring, we decided that employing the GPO "Delete user profiles older than a specified number of days on system restart" would be the way to go. We set it to any profiles older than 7 days.
Now, we have 2 devices from the same set come back with differing results: 1 has deleted all accounts, bar the last Admin to have logged in (the local Administrator account had been deleted) and the Public Folder. The Regedit records have an incomplete list of profiles, listing only:
- %systemroot%\System32\config\systemprofile
- %systemroot%\SystemProfiles\LocalService
- %systemroot%\SystemProfiles\NetworkService
- The last logged in Admin profile
- Several corrupted/empty profile entries
Any attempts to sign in using another profile states:
The User Profile Service service failed the sign in.
User profile cannot be loaded.
On another laptop, it however has done nothing - not even deleted a single account that was over 12 months old.
What could be causing these problems?
