How do I make a backup copy of my XP home edition operating system just in case something happens some day? I got a box of CD-RW Rewritable 4x discs from Staples but don't know how to use them.
When I do a control/alt/delete and get a box that shows about fifty or so processes to be running,,, how do I know which are good ones and which may be some sort of spam or bot that my computer has picked up somewhere?
