Enabling Administrator protection in Windows 11 significantly improves security by addressing critical User Account Control (UAC) weaknesses. Unlike UAC’s split-token model, where elevated processes share the user’s session and can be exploited by malware, Administrator Protection creates a separate, system-managed administrator account (SMAA) that generates isolated, just-in-time admin tokens for each task, which are destroyed immediately after use.

Entering a PIN is one of the authentication methods available through Microsoft’s Windows Hello. It offers a simplified sign-in experience, especially for devices that lack biometric capabilities. This option must be explicitly enabled in domain-joined environments or those using Entra ID. However, its functionality is significantly restricted on virtual machines hosted on Hyper-V.
