Windows 10: Windows 10 Pro Key suddenly marked as invalid, Windows 10 key no longer activated

This problem is very frustrating to me because I don't see where the issue lies in.

Some months ago I bought a Windows 10 Pro key off of some site. Because it was very cheap I contacted their support and asked if it was legit. Turned out it was because I could use the Pro Key without any activation problems for months up until yesterday/today. Yesterday I received a notification for the new windows insider build in the fast ring. It downloaded and everything but when it was installing, observed in the windows settings, I shut down my PC when it was at 0 %. Today, I booted Windows 10 and received and annoying pop-up telling me to activate windows. Because I was convinced my key is all right I ignored it and continued using my PC. After a while I checked the system settings and navigated to the license settings. I received several more hints that my license was somehow deactivated:










Does anyone have an idea on how to fix this.

windows 10 key

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

I just did a deployment last night with a fresh 10 install using the newest ISO and a 7 Pro key, worked like a charm. Glad yours worked for you as well. *Toast :toast:

 

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.
