...System/Harddrive? I'm thinking of upgrading my Motherboard and make a large leap from Intel Pentium 4HT to Quad Core. I recall something about MS Windows registering my Windows key with the Processor. So if i get a new processor do i have to jump though hoops with microsoft? I'm working with keys from a MSDN liscense, so i'm liable to be told by microsoft i've got extra keys and just eat it.Well i might go duo core instead of quad, but lets not bog down in those details, i'm focused on the operating system.Also, i run multiple partitions and two operating systems(i run win XP professional partition 1, backup partition 6, and linux ubuntu 7.04 on partition 7) so will that be effected?Is http://support.microsoft.com/kb/824125 accurate or is microsoft lowballing its difficulty?
