Windows 10: Can't Activate Windows 10 after major hardware changes

I bricked my Intel NUC Mini PC, but thankfully the manufacturer replaced it under warranty. After I reinstalled my SSD drive and memory sticks Windows 10 Pro popped up an error message saying that I needed to activate Windows. I have my Product Key but it won't accept it saying it was already used. I tried all of the MS Support documentation on-line but nothing worked. Any further suggestions?

Windows can´t activate after hardware change.

Yesterday I made a major hardware change (I changed motherboard, processor, Ram, and CPU Cooler) and when I started My PC I realized that Windows 10 was not activated.
Then I went into configuration, activation, troubleshooting and there I selected change hardware recently, even so, windows

said it can not be done because the servers are not available.
The same step I did yesterday and today. Solutions?

Activating Windows 10 after a major hardware change.

I recently made a major upgrade to my computer that involved replacing the CPU, motherboard, and memory, and to make sure that no old drivers messed up the works, I performed a Reset install (chose to keep files). Now the machine was previously a Windows
7 Pro machine that was upgraded to 10 Pro in the free upgrade program several years back. This means the activation is tied to my Microsoft account and all I have to do is make sure I'm logged into the machine to activate it. However, I'm being asked to
activate Windows, and when I follow the instructions to activate after a major hardware change (go to Settings, Activation, Troubleshoot, select "I changed hardware on this device recently," select the device from the list, and click Activate), I get a message
that says, "we can't reactivate Windows on this device. Try again later." Is there anything else I can try, or do I have to buy a new licence?

 

Activation after reinstall with major hardware change not possible

Hi,

I did a major hardware change on my desktop pc (Motherboard, Ram, CPU, SSD). During this I did also do a clean install of Win 10 Pro.

As many Internet Sites suggested I did an slmgr /upk on my old installation before the reinstallation.

I did enter my product key during the installation. But now it is not possible to activate my windows installation.

In the activation troubleshooter when I click "I did change hardware" only my old installation is listed (different hostname). I am using the same microsoft account for login as on the old installation.

Due to my work times its hard to get in touch with the phone support during bussiness hours.

I hope you can help me.
