Not sure is this is the right spot to ask if not forgive me. I have a question on a restricted user on Windows XP Professional is there a way to let the restricted user be able to run defrag or to have it as a task and run under administrator at certain times?Thanks for your help

Yes, you can schedule defrag under alternate credentials. See here: http://www.windowsdevcenter.com/pub/a/windows/2005/10/04/hands-free-disk-defragmenting.html
