Windows 10: Windows 10 Pro was just deactivated

My system just changed from activated to not activated. Windows 10 Pro Version 1809, OS Build 17763.55.



Ran the troubleshooter and its telling me that I need a Windows 10 Home Product Key and that I don't have Windows 10 Pro. I upgraded from Windows 7 Ultimate to Windows 10 Pro when they had the free upgrade. Been working just fine up until now.

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Windows 10 deactivated itself after update

I bought the windows Pro last year and the code is valid until the recent windows update and now this is showing that my Windows is deactivated.

Please help. I followed the steps and tried to call the phone number that shows up when you search using the
SLUI 04 and there seems to be a dead number and the call does not go through.

This product key was on the back of windows 10 Pro DVD that i bought and shamefully now windows says that this key is not for Windows 10 pro. how is this possible?

Please suggest steps to get this resolved. other than the ones you already mentioned here.

Thank you.
