Windows XP help

[AbbeySider]

I upgraded a friends PC with new RAM and a new HArd Disk.
It was an old Compaq Pavallion and he didnt have the money to buy a new PC.

I used a Dell Windows XP CD to install the OS. I bypassed the Windows Activation and it was fine for a while.
Windows updated itself and it seems that the Windows activation is now broken so I have to reinstall the OS.

I am getting an original OEM copy of XP with a legit Key-code of another friend.
Im assuming that it will install Ok with the original CD and Key-code.

Will I be asked to activate it again and enter another Key?
Or am I correct in assuming that with an OEM version that you enter the key-code with the CD and it works fine?

Actually im not 100% sure if the copy im getting is an OEM version but I think if you are activating it that you can chose to do so over the phone and it never asks again...
