slmgr /ato
π After this, Windows should be activated for 180 days (in some cases). You may need to repeat after expiry or automate renewal.

Another simple way is to use a pre-written batch file. It works by executing the above commands automatically.
π Instructions:
- Open Notepad and paste the script from trusted sources (avoid unknown files).
- Save it as

(Choose "All Files" while saving). - Right-click the file and run as administrator.
