Hi, I'm John! I will help you with this.
To help narrow down the issue:
- Did you recently reinstall Windows, reset the PC, or change any hardware (like the motherboard)?
- Was Windows 11 previously activated on this device?
- Did this PC originally come with Windows pre-installed, or was Windows purchased separately?
Also, could you please share a screenshot of your Windows activation details?
Please follow these steps:
- Press Start and search for CMD.
- Right-click on Command Prompt and select “Run as administrator”.
- Run this command:
slmgr /dlv
- A window will pop up with activation information.
- Please take a screenshot of that window and share it here. (You can cover or blur the full product key for privacy.)
