Hi I'm upgrading my entire computer except for my good old XP operating system. I'm planning on using the harddrive from my old computer as well as a new hard drive for additional space. I heard somewhere that when updating your computer to a different number of cores you need to re install Windows. I've only heard that from the one source so im not sure if this is true. so my basic question is: To switch computers but keep the same operating system are there any extra steps I should take?
Also as a side note I plan on updating to Windows 7 in the future is there any sort of upgrade discount I can get for having XP?
