    Error activating the Windows 11 key even though it worked previously


    When I turned on the computer for the first time and ran Windows according to the key written on the back, everything worked and there were no errors. However, now, half a year after starting Windows 11, the message from that code appeared on the screen: "Activate Windows, Go to settings to activate Windows". When I entered the settings in the "System" tab, at the very top it said "Windows has not been activated". After clicking "Activate now" and then, when it took me to Activation, I clicked "troubleshoot. However, I got "The system cannot be activated on this device" and error 0xC00
