Windows 10: Windows activation key stopped working

Hello,I bought my windows activation key in 2023, and recently upgraded CPU's. I think this may have caused windows to stop working, as I now have "Activate Windows" on my screen. Every time I troubleshoot windows through settings saying "I changed hardware on this device recently" I get a "oops, something went wrong" response from microsoft. I hope there's some way of resolving this.

There is no difference between the OEM disc and the Retail disc with Windows 7. A retail disc will accept a OEM or Retail key, and vise versa.

If the OEM Key wasn't going to work with the disc you have, it would have stopped you during the install when it first asked you for the key, not during activation.

What is likely the problem is that, since the OEM version has already been activated once, it is failing activation again. Activate it over the phone using the option given to you on the failed activation screen, and you shouldn't have a problem activating it.

Well it didn't stop me because I told the installation program to activate the key later, so I didn't put any key during the installation. Maybe can it work if I put the key when it asks me in the installation?

Win7 and Vista. It did not work with XP, OEM and Retail discs were different for XP(and anything pre-XP).

If it is already installed, you can enter it when you activate.

Is it saying the key is not valid or is it failing activation? A screen shot of the error it is giving you would help a lot.
