[SOLVED] explorer.exe keeps crashing

Hi all!

I'm using Windows XP SP2.
explorer.exe always crashes when right-clicking on a folder, file, and even Start menu.

This *only happens when logged on as an ordinary user (limited account).
When logged on as administrator, this doesn't happen; everything goes normally.

If I make the user account an administrator account, then this goes back to normal. But for security sake, I intentionally want to limit this user account as an ordinary user.

Any solution to my problem is very welcome.

Thanks in advance!
