I am having issues with my computer and I believe it may be a problem with the drive image I have installed on the system. My computer came with a "recovery" CD including Windows and all the other junk a computer manufacturer pre-loads on the machine. I want to do a clean install of Windows only. I have my Windows XP Home OEM SP1 product code. If I obtain a copy of a Windows XP Home OEM SP1 disc, can I use my own product code (license) or does Microsoft's new anti-piracy activation process prevent even legitimate use like this?
