Possible reason for >>1)
For recovery purposes, every time a user successfully logs on to Windows, a copy of the registry is stored in the "Last known good". This way, if you replace your video drivers with a pile of pudding, you can revert to "Last known good" on boot and start up with the old drivers, avoiding a messy situation.
I don't know this for sure, but it is possible that, rather than make a separate copy of the registry, it would save a pointer, and put a lock on the last known good. If true, the reason you were able to delete the profile is not because of the reboot, but rather the successful logon, moving the pointer and lock to the NTUSER.DAT of the Administrator user.
Without the precise error message for the second case, I don't have any quick answers.

Two questions which I think might be related. Both are on systems running
Windows XP with SP2.
1) I log on as "Larry" then log off. I log on as Administrator and try to
move or delete the profile for "Larry" and get the message that NTUSER.DAT
is in use by another user. If I re-boot, the problem goes away.
2) I have a PC used by the instructors in a classroom. Occasionally when
someone tries to log on they get a message that their profile can't be used
(the profile is there). I don't recall the exact message as every time I
go over and try it things work okay but others are still having this
problem. Once again, re-booting fixes it. Then for a while all seems okay.
A solution (explanation) would be great but if not, a suggestion on where
to look. I did go to the Microsoft Web site but not knowing the exact
message made it a bit hard to search.
