Hello,
Are you using a legitimate license to activate the system?
If you use a legitimate license to activate the system, it is by definition valid for lifetime. Unless you are using an OEM license, and you have replaced the hardware. Because the OEM license is tied to the hardware.
Go to Setting>System>Activation>Activation State, check Activate State.
Or you can try to activate system by phone:
- Select Start > Settings > System > Activation.
- Under Activate Windows Nowsection, select Activate by Phone.
Have a nice day.
Best Regards,
Hania
