I installed an original version of Windows XP home edition that I borrowed when I purchased a new mohterboard/processor/case/hard drive, etc since I only had restore disked provided for my COMPAC and Acer notebook computers. I found out that Micro Computer had Windows XP Home edition with SP 3 (system builders)available and purchase a copy and want to install it.

The question I have is there anything else I need to do other than putting the CD in the DVD drive to install the new version over the old other version?
