I'm building a new PC and I want to migrate my Windows 10 installation from an older machine that I'm planning to recycle. I've created a Windows 11 installation thumb drive, and I'm hesitant about whether I can use the Windows key from the old PC to activate Windows on the new system. The key is not tied to any manufacturer since I bought it directly from Newegg, but I'm worried that since it's specifically a Windows 10 key, it might not work for Windows 11. The reason I couldn't upgrade the old PC to Windows 11 is that its CPU isn't compatible. I'm really hoping to avoid purchasing a new Windows key.

Typically, OEM keys are non-transferable, as they're meant for a single activation. You usually can't move them unless Microsoft allows it, which sometimes happens if you claim you've replaced faulty hardware. If you successfully transfer it on your own, it sounds more like you bought a regular key instead of an OEM one.

Yeah, it seems like there’s often confusion around OEM keys. Just make sure you reach out to Microsoft if you want to try transferring it. Good luck!
