I have an original copy of Windows 2000 Advanced Server. My question is, is this the same windows 2000 that I can use on my regular computer (not server), or are there diffrent versions of Windows 2000 that are diffrent. I think it is time that I upgrade my boxes from Win 98se and Win ME, and was wondering if I should go with Win XP or use the copy of windows 2000 I already have? So basically can the version of Win 2K Advanced Server be used on my gaming rig?
