Why Use a Windows 7 to Activate Windows 11?

There are a couple of reasons why using a Windows 7 key to activate Windows 11 makes sense. The first one is that if you’re a long-time Windows user, you might already have one. You could have a perfectly usable key sitting forgotten on an old PC, saving you time and effort.

You can reuse Windows activation keys on a different computer as long as it isn’t a key for anOEM version . OEM software is generally tied to the hardware it comes with.

But even if you don’t already have an old Windows 7 key to hand, buying a new one will almost certainly be cheaper than buying a Windows 11 key. You should be able to find one for a couple of dollars.
