Can't activate Windows 8 on another (new) computer

Question

Microsoft

I changed my computer, installed my legal copy of Windows 8 on it.
However, the system swears, saying, “This key did not fit. Make sure you enter it correctly, or try a different key."

As I understand it, this is due to the fact that the system can only be activated on one PC at a time. But ... on the old PC, the hard drive has been formatted for a long time, i.e. The OS is only on one PC at the moment.

Tell me how to let Microsoft know about this or, more simply, how can I activate Windows?

Answer 1

To activate Windows 8 (license for upgrading from Windows7) you need to:
1. DELETE everything
2. INSTALL Windows 7
3. ACTIVATE with the old key FROM WINDOWS 7
4. Install Windows 8 OVER 7.
5. Activate Windows 8 with the upgrade key.

Answer 3

you most likely bought a key for updating, so in order for the key to fit, you must first install your copy of win7, then roll 8 from above. I also encountered this at one time
