Windows activation after bios update

Same problem here with MSI motherboard (Z790 Mag Tomahawk wi-fi ddr5), I purchased a digital license of Windows 10 professional (Retail),

directly from Microsoft store. I used it for some years on al old PC, last month I changed machine and made a license transfer from the old PC

to the new one.

Worked like a charm until BIOS update, which lead to deactivation issues. My new PC was listed twice in Microsoft account, together with old PC

and a laptop I own. I tried pretty much every solution in these posts, no luck till now. Luckily I made a system image just before the BIOS change,

so I performed every method you could possibly think, using the activation troubleshooter:

• fresh install of the OS
• restore of the system image
• recover the key from regedit

Finally I just deleted the two instances of the new PC from the account. Now, after yet another fresh install of Windows, I can see this PC only showed inside my personal Microsoft account, while the troubleshooter only shows the old PC and the laptop.

I already opened a support ticket, attaching a copy of my windows license and motherboard invoices.

The only way to contact Microsoft support available in my country (Italy) is to open a support ticket, leave a cell number and hoping for the best, waiting

to receive a call from customer care. Both phone and live chat are unavailable for me.

My question: any of you guys have to deal with this kind of customer support where you leave your phone number and wait for a call? How much time did you wait before to be able to speak with an actual person trying to solve your problem?

Thanks all in advance,

best regards

I tried every trick mentioned here and ultimately went back to my old Windows 8 install key for activation. It took it and has been OK for about a month now.

Same issue: Asrock z690 Extreme Wifi w/ 13th Gen Intel Core i5-13600K

OEM license, called microsoft they said it was blocked as it'd been used twice already. this lines up with the fact that I was on my 2nd flash since activating. They were unable to resolve the issue.

No, this was with Windows 11. To fix it, I ran "slmgr /rilc" in an administrator command prompt, rebooted, logged in using a Microsoft account rather than the local account I normally use, then went to activation in Settings, clicked on Troubleshoot, and then clicked the link saying something like "I have changed my hardware", and was able to re-activate. I then had to go to accounts and setup my local account again.

Mine deactivated after MSI Z690-A Bios Update. That fixed it for me. Thanks
