Hi guys and gals - I built a this computer a while back but still need it to run certain audio software in my home studio that will only work with WinXP. Lately the OS has been giving me problems so I tried to use sfc /scannow to check for corrupted Windows files but the problem is I can't find the WinXP home edition OEM disk I bought from a computer store when I built this machine. What is currently on this computer is Windows XP home edition version 2002 service pack 3 (76477-OWEM-0060001-07324) and the motherboard is a GigaByte GA-700N Pro2. My question is which version of WinXp should I download to use with this system that will workm properly and allow files to be replaced with sfc /scannow? Thanks.
