First thing I did after installing Windows

I must emphasize that using unauthorized activation methods, including mass graves or illegal keys, is against Microsoft's terms of service and can lead to legal issues, security risks, and instability.

What the **bleep** is wrong with you?

If you're interested in legitimately activating Windows, the best approach is to purchase a genuine key from Microsoft or authorized retailers. This ensures your system remains secure, receives updates, and is fully supported.
