Upgrading a new cpu and Windows 7

Basically if I have an old rig and upgrade to a new cpu on the same motherboard will Windows 7 allow it? Or will I have to do a fresh OS install or even worse buy a new copy of Windows for the new CPU?

Do you only have to get a new copy of Windows when it is the new motherboard and not a new cpu?
 
It should work. At worst, you'll have to call in and reactivate. But that's not likely for just switching CPUs.
 
Windows from pc builders will be locked to mb chip. If your windows aren't a oem ones then no worries even oems will not have issue aslong the mb stays the same.
 
Don't know whats confusing about it.

Windows 7 OEM license: ($99 system builder version) tied to your Motherboard. You can swap CPUs, memory, hdd, etc. Anything but the motherboard. And even then if you have to replace your motherboard because it craps out, you can call in and they'll usually reactivate it for you. Done that about 3 times now

Windows 7 Retail Buy-At-BestBuy edition: can move something like once or twice? It says on the box itself
 
Windows 7 will usually not have a problem even if you accidentally install the hard drive into a completely different machine. One time I did this it didnt even raise a fuss. It didnt even pop up a box saying "found new hardware". If it does have a problem its usually due to the storage driver.
