Title
User Account Control must automatically deny elevation requests for standard users. (Cat II impact)
Discussion
User Account Control (UAC) is a security mechanism for limiting the elevation of privileges, including administrative accounts, unless authorized. Denying elevation requests from standard user accounts requires tasks that need elevation to be initiated by accounts with administrative privileges. This ensures correct accounts are used on the system for privileged tasks to help mitigate credential theft.
