Just started happening today: “Windows 7 build 7601 This copy of Windows is not genuine” is displaying on desktop, lower right corner.
Windows Update icon disappeared from taksbar. Can no longer launch Windows Update from Start menu.
Navigated to Control Panel > System and Security > System. Under Windows Activation section it says “Status Not available” and “Product ID: Not Available”.
I’ve had this machine since 2013. Dell XPS 8700 Win 7 Home Premium SP1 x64 (Intel)
Any ideas why my PID apparently just disappeared, rendering the OS “not genuine”? Any chance it might be related to use of W7ESUI_0.2 to update?
