PC ran out of HDD space and now users can't log into accounts.
Took drive out and put it in another PC to free up space (7.8 GB free of 80GB)
Put drive back in original PC. Boots up, Windows log in screen comes up, log into account and then windows looks like it's logging in with user profile, but then closes that login session and goes back to log in screen. This happens for all accounts even in Safe mode and even for the administrator account, since I tried logging into that account.
When HDD was in the other PC, I noticed that there were a number of Temp folders in the User account folder, Temp.Desktop, Temp.Desktop1, Temp.Desktop2, Temp.Desktop3. Were these created when the HDD was full??
How to recover login sessions?? Delete Temp.Desktop folders and reboot??
