I'm considering reinstalling my Windows, but I'm not sure wich way to go. I have an XP Pro SP2 and a Windows 2003 R2 CDs. Should I install XP Pro? I'm asking because 2003 R2 is a more recent OS and has a higher built number, so I guess it's more stable? I will use the guide at win2k3[dot]msfn[dot]org. Any suggestions?
