Unfortunately, you haven't told us what "the provided steps" were, so we can't help with that.

If you need to activate Windows after a hardware change, that likely means that the hardware you changed was the computer's motherboard. In that case, you have to purchase a Retail copy of Windows (which you appear to have done) and perform a clean install. During the install, you will be asked to enter your license, which will activate the computer after the install has completed.

You probably know that a 'clean install' means that you erase your hard drive and reinstall all your software. If you haven't done this before we'll be glad to help.

(I would guess that you are referring here to Windows 11, since that is currently the only version of Windows for which you can still purchase a legitimate Retail license.)

It was a Windows 11 license, but upgraded from a Windows 10 retail license (which you could purchase in the past)

The old Windows 10 retail product key is no longer accepted and the various methods MS provides (activation trouble shooter, portal) just return errors with no details. Based on my understanding of the licensing terms this should still be transferable but it doesn't work.

There are many references in the help material to contacting MS support, but all of the "contact us" links now appear to route to self-help or return errors and the phone based method was just discontinued.

If, in fact, you changed the computer's motherboard, your previous license is no longer valid.

For the purposes of Windows activation, a computer with a new motherboard is considered to be a new computer, and a new computer needs a new license. That means you'll have to purchase a new Windows 11 license.

That is true for an OEM license, but this was a much more expensive retail license that's supposed to be transferable after a hardware change. The problem is that this is a discussion that should be occurring with a MS representative / employee instead of a community member.

As far as I can tell there is no longer any way to directly contact MS support. If I purchase another retail license for several $100 and their system rejects the code with an error what do you do?

Did you buy the license from Microsoft, or third party?

You said it was retail, did you confirm it back then with command like slmgr /dlv or you were told by third party seller that it was retail? A lot of resold keys claimed to be retail often turned out to be volume license.

Hello,

Did you purchase from Microsoft, or from third party?

Is it originally a Win7/8 key?

What type of hardware change? Did you end up reinstalling Windows?
