Hello Egor did you try to see if you have digital license embedded in you Microsoft Account?
Did you Upgrade from WS10 to WS11?
Also I made a little researcher for you so you can try this troubleshooting;
- Open Settings → System → Activation.
- Check the Activation state:
- If it says Windows is not activated, click Change product key and enter a valid one.
- If you upgraded from Windows 10, ensure you're using the correct edition (e.g., Pro vs. Home).
To check your key from the command line, run:
sh
CopyEdit
slmgr /dli
If you need to re-enter your key:
sh
CopyEdit
slmgr /ipk <your-product-key>
slmgr /ato
f activation is stuck, try forcing activation with:
sh
CopyEdit
slmgr /ato
Or check the activation status with:
sh
CopyEdit
slmgr /xpr
