Windows 10: Recent PC upgrade is unable to reactivate windows

I built a new PC and moved my SSD from the old PC to the new one to avoid re installing windows, however when I go to reactivate windows it has already been reactivatedI bought the copy of windows 10 new for the old PC and it has only been on that PC until now. I have also tried putting the key in manually and it wasn't accepted.

Unable to reactivate Windows 10 after hardware change

Hi there,

I recently upgraded system hardware including Motherboard and am unable to reactivate Windows 10 via the activation troubleshooter:

I have tried removing my old PC configuration from the list of devices in my windows account but still no luck!

• My windows account was linked to my PC prior to the change
• Login in / out of my windows account has no effect
• My version of windows was a free upgrade program from Windows 7, would this be an issue?

Any help and ideas would be appreciated!

Many thanks,

 

Unable to reactivate windows on a new PC

I had earlier asked a question here on SU.SE. It was suggested to me that I should firstly deactivate windows on older PC and then try to activate windows on the new PC. I have deactivated windows on the older PC by slmgr /upk, but I am unable to activate windows on the new PC.

I have followed Activation> Troubleshoot> I changed hardware on this device recently> Unable to Activate Windows > See other devices linked to your Microsoft account, I get the following message (attached as image). In the attached image my windows is listed, but mentions as Windows isn't Activated and I do not get the option to select the windows.

Have I followed a wrong procedure? What should I do next?





PS: I have a Retail license of Windows

 

How do I reactivate Windows after upgrading PC?

Hi there,

I'm upgrading my PC in a few days and just wanted to be prepared when it happens. I'm replacing the mobo, RAM, GPU, PSU and CPU. My Windows installation is a student Windows 7 64bit upgrade, upgraded from a Vista 32bit OEM.

First question: I'm going to try using sysprep to strip my installation of old drivers and hopefully successfully replace them with new drivers. Should this work?

Second question: Will this upgrade invalidate my Windows license? And if so, will my PC be unusable?

Third question: If it's invalidated, how do I reactivate it? Can I re-enter the license or will I have to reinstall? If I reinstall, would the 7 Upgrade activate, as well as the Vista OEM?

Basically, the best case scenario would be that I won't have to reinstall Windows for the time being, and can do it at my leisure.

Thanks in advance!
