Windows XP SP3 computer crashed. Could have been viral, although AVG was loaded, up to date, and doing daily scans.
Instead of starting from scratch, reformatting and installing all the programs on that hard drive, I'd like to "repair" the installation, but I cannot find the original installation CD.
Can I buy a NEW copy of Windows XP, SP3, and use that new disk to do a repair?
Can I buy Windows 7, and use that to upgrade to Windows 7, keeping the installed applications working without reformatting?
I don't believe you can use Win 7 to attempt the repair.
