How to check UAC – User Account Control is enabled or disabled

25 February,2015 by Tom Collins

Answer: User Account Control (UAC) is a security component that enables users to perform activities as  non-administrators (called standard users), and as administrators without having to  log off or use Run As.

When a user account is part of the Local Administrator group  , in reality the user performs most tasks as a standard user. Separating the non-administrative and administrative tasks , decreases the security  risk.  Malicious software can exploit  UAC being disabled. Malicious software can be installed without any notification
