My personal copy of Windows 10 Pro decided that it is no longer valid as the key stored on the Microsoft servers is only good for Windows 10 Home. I even ran the Windows troubleshooter where it listed all of the valid Windows 10 Professional licenses stored on my Microsoft account, but still told me that I only own a Windows Home license. It then pointed me to the Windows Store to purchase a new license after revoking my old license by placing the Windows Activation watermark on my desktop. After researching this annoying message the entire night, I discovered lots of other valid Windows license owners with the same issue. It seems that Microsoft knows about the issue and a fix is coming. At least my data didn't disappear into thin air. That would suck if it did it twice. User: Having had a legitimate copy of Win10x64 Pro since release, today I have been presented with an activation error (0xC004C003). Running the trouble shooter tells me that I I have a Win10 HOME licence (which is a false statement). Looking at my MS account online it clearly states I have a pro licence. There has been no hardware changes. Support: Microsoft has just released an Emerging issue announcement about current activation issue related to Pro edition recently. This happens in Japan, Korea, American and many other countries.I am very sorry to inform you that there is a temporary issue with Microsoft's activation server at the moment and some customers might experience this issue where Windows is displayed as not activated. Our engineers are working tirelessly to resolve this issue and it is expected to be corrected within one to two business days. This is the response from Microsoft support. I would advise you to wait for a day or two.
