Woke up this morning to find out my PC is suddenly not activated. I tried going through the troubleshooter and but it runs into an error and can't reactivate itself. I tried re-entering my product key but it says it can't be used on this copy of Windows. The even stranger thing, it says my digital licence is a 10 home licence. However, this key has been a working 10 pro licence since 10 was released, and was previously a retail Windows 7 Professional copy which was even bought from OcUK back in 2010. I tried going through the phone options but so far it's been useless. I'll probably try again later but I'm struggling to get an actual person to talk to. Has anyone else seen this happen? EDIT: Looked on Reddit, seems I'm not the only one with this issue and it could be a problem with the 1809 build, it's the only thing I can see that we all have in common: https://www.reddit.com/r/Windows10/comments/9v4hs7/windows_10_cant_be_activated/ https://www.reddit.com/r/Windows10/comments/9v6ibm/windows_10_pro_suddenly_not_activated/ EDIT 2: A little more reading some 1803 users are also affected. Definitely seems like Microsoft messed up something on their end so will give it a couple of days to see if that fixes it. Managed to get the right options to finally talk to a person on Microsoft support, but was held for over half an hour so had to hang up to get to work. EDIT 3: Someone managed to get through, and seems Microsoft has acknowledged they have an issue with the activation server so they're working on it: https://www.reddit.com/r/Windows10/comments/9v6ibm/windows_10_pro_suddenly_not_activated/e9a5rkk/ https://answers.microsoft.com/en-us...ctivated/fe9a4ecf-2e2a-491d-a43e-b010c316d1c4 Final EDIT: They seemed to have fixed it. Run the troubleshooter and Windows should be activated again.
