Using System Restore - Learn how to use XP System Restore
When a Windows XP user asks how to fix a problem they've recently started having with their PC my first response is to use System Restore to roll it back to a point just before the problem started. I've found the majority either don't know how to use it, don'what it does, turned it off because it uses too much disk space and virtually all say that Microsoft's Help file is not very helpful to which I'd agree.
