User Account Control (UAC)

User Account Control (UAC) is a security feature in Windows that helps prevent unauthorized changes to your computer. When a program or user tries to make significant modifications—like installing software or changing system settings—UAC prompts for permission, ensuring that such actions are deliberate. This mechanism acts as a safeguard against malicious software and accidental system changes, maintaining system integrity while allowing users to perform necessary tasks. Essentially, UAC acts as a gatekeeper, balancing ease of use with security.
