This is my first time posting here so apologies in advance if I miss anything.
Here's my problem, I want to change my motherboard and cpu in my system, which should go fine but I am worried about reactivating the OS if this is needed (I've read that sometimes this is not needed when changing the motherboard). I have an OEM version of windows as I bought my PC from a small system builder.
I believe you could only reinstall it, if you are are replacing the motherboard with the same make/model. Legally the OEM version is bound to that specific motherboard. And upgrading to a new motherboard you would have to purchase another copy of windows.
