i recently upgraded a computer. windows 10 deactivated itself due to the hardware change. i tried everything i could to reactivate. microsoft support told me my only solution was to buy a new license. microsoft treats its customer with contempt.

If you can deupgrade... Deupgrade, make sure it reactivates, then create a local account tied to a microsoft account and reboot and check activation page until it says activated with your microsoft account.

Then upgrade and reboot until it deactivates, then it should let you fix it with your microsoft account... Once that happens, you can remove the microsoft account from your computer.

At that point, find a reseller site and buy a key for cheap or just don't activate Windows at all. I don't think you lose much "features" when leaving it unactivated. It's not worth your time to deal with Microsoft support over Windows activation keys in 2026.

I'm curious did you have an OEM license or a retail license? OEM licenses die with the mobo.

[bigstrat2003]

OEM licenses are for the computer, not the motherboard. The online activation historically hasn't worked if you change motherboard, but the phone line folks would always activate it for you if you explained that it was the same computer with a different motherboard.

TIL. I always heard that their licensing people tended to uphold the motherboard line.

i bought a builder license from newegg in 2017. unfortunately i was not diligent about saving the product key. this was actually the third time i had been in this scenario after changing hardware. no idea why it wouldn’t work this time around.
