Windows 10: Sudden activation Error

Anonymous

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

We are aware of reports that some customers’ Windows 10 Pro and Windows 10 Enterprise machines are not recognizing their licenses as activated. Users may receive the following notification: “Error: you are running Windows 10 Pro, but you have valid digital license for Windows 10 Home," or one of the following error codes 0X803F8001, 0xC004C003.

We are actively working to resolve this within 24 hours. You can still use your PC; however, the watermark will appear until activation is restored. Thank you for your patience.

We will update this post with additional information as needed and once activations are restored.

    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.

    Three systems got nicely deactivated this morning.  The October 2018 update has had several significant issues.  What a horror show with Microsoft of late.  What's going on with the company?  Qaulity control has reached a new low.  If someone was trying to sabotage the company, this is how to do it.
