I have built a new PC and want to redeem a Windows key. I have Windows 10 on my laptop. Can I somehow transfer it from there to the PC? If so how and do you have activated Windows 10 on both devices?
No that is not possible.
You need 2 keys.
You buy 1 jacket and 2 people are supposed to wear them at the same time. Does not work
Or you still have an old Win7 or 8 key.
With that you can also activate Win10.
Everything is possible but what you want is not allowed.
Depends on. W10 can be activated 3 times. However, it can only be legal on one device at the same time.
If you have the key it works. But if it is a version that depends on the CPU type, then it does not work. Laptops often have a variant close to Hhomework
