Unlike the standard Home edition, Windows 11 Pro is designed for professionals, entrepreneurs, and power users who demand advanced security, business tools, and virtual workspace options. The Pro Key functions as a license that unlocks the full suite of the OS's extra capabilities. Without a genuine key, the user experience is restricted, and some critical features are disabled.
