"I thought that I could use system restore to take the pc back to a time when I would have this programes" doesn't make it clear..
Have you tried restarting the computer into Safe Mode, log in as the "administrator" login, then find the "start/all programes/accessories/system tools/system restore" link.
How To Start In 'Safe Mode'
Hope this helps.
I've been trying to learn how to back-up my PC. I have windows XP and am using a usb external hard drive to hold my document and setting files. I now go to start/all programes/accessories/system tools/ at which point it says internet explorer (no add-ons)what has happened to the rest of my all programes? I thought that I could use system restore to take the pc back to a time when I would have this programes. Thanks
