Where it tells you it is deactivated, it should give you a local phone number to call. This will 'probably' get it reactivated. Failing that, you'll have to call and talk to a human.

It's saying 'in use on another computer', because Windows treats the motherboard as 'the computer'. When it was originally activated, it knew the old motherboard. Now, trying to activate again, it sees a new one.

Is this a retail windows 8 or a oem win 8 you purchased for a PC you built
Or a oem windows which came on a PC you purchased
Only in first two cases is licence transferable

If it will not activate on line you need to phone Microsoft activation centre and ask for help

Usually their question is how any PC's is this windows copy installed on , the key will tell them what the version is

If more than one PC no re activation

Can you get windows activation to give you the phone number ?
