Can't re-activate WIndows 11 after CPU and Motherboard upgrade

Gordon Fenton 20

I upgraded my motherboard and CPU and now can't re-activate WIndows 11. I followed the online instructions and made sure my Window 11 was a digital license linked to my MS account. But when I click on the "troubleshoot" option, it says that there are no devices that I can use to transfer a license.

Hello

Being digital license alone doesn't mean the license is transferable.

How did you obtain your license initially?

Did it come with the device preinstalled, or did you purchase it?

If you purchased it, did you purchase from Microsoft, or from third party?

Is it originally a Win7/8 key?

Without knowing the exact type of license you had, it is difficult to confirm whether it can be transferred.

For example:

If it was an OEM license, it is normally tied to the original motherboard. Once the motherboard is replaced, that license generally cannot be transferred, even if it was digitally activated.

If it was a volume license, you would need to obtain the product key or activation assistance from your school or organization.

If it was a retail Education license, we would also need to know whether it was a full license or an upgrade license.

An upgrade license depends on the underlying Windows Pro license. For example, if Windows Pro was originally activated with an OEM license and the motherboard was replaced, the Pro license may no longer be valid. In that case, the Education upgrade would not activate either.

If it was a full retail digital license, you can try the following:

Go to Settings > System > Activation.

Select Troubleshoot.

Choose I changed hardware on this device recently.

Sign in with the Microsoft account linked to the digital license.

Select the old device from the list.

Check This is the device I’m using right now, then select Activate.

See whether Windows activates after completing these steps.

Thanks, EmilyS726, for your time and patience. I never really understood the difference between MS's various licenses before now, but I agree that I have no clue what sort of license I had! I have thus purchased a non-transferable license at a third of the price of the transferable license, so I can upgrade two more times and still break even! Again, thanks for setting me straight.

I built the computer in 2019. It is one of my research computers at my university, and I think that I must have gotten a Windows 10 key from my university (it is the Education version). I don't remember purchasing a key. I then migrated it to WIndows 11 in 2021 or 2022, and had no problem doing so.

That doesn't qualify the license to be transferred? If I put the old motherboard and CPU back into this case, do you think that Win11 would be re-activated?
