Study Notes

User Account Control (UAC)

UAC is a security feature that prompts users for administrator privileges when necessary.
Standard users have limited access, while administrators can perform any action.
Administrators should log in as standard users for security purposes.
UAC elevates privileges for applications that require administrator access.
UAC prompts users for confirmation in Admin Approval Mode.
UAC can be disabled, but this is not recommended.

UAC Concepts

UAC levels are configured in Control Panel.
The "Always notify" setting is the most secure.
"Notify me only when apps try to make changes to my computer" prompts only for changes to system or Windows settings.
"Never notify" disables UAC prompts completely.
UAC prompt settings can be configured in Group Policies.

UAC Levels

Always notify: Secure desktop displays for 150 seconds, user must approve actions.
Notify me only when apps try to make changes to my computer: Prompts only for system modification attempts.
Notify me only when apps try to make changes to my computer (do not dim the desktop): Same as previous, but without secure desktop.
Never notify: No UAC prompts, all actions executed without approval.

Additional Settings

User Account Control: Only elevate executables that are signed and validated: Requires PKI signature verification for applications requesting elevation.
User Account Control: Only elevate UIAccess applications that are installed in secure locations: Applications with UIAccess integrity must be installed in secure locations, such as Program Files and Windows\system32.
User Account Control: Run all administrators in Admin Approval Mode: Enables Admin Approval Mode for all administrator accounts, requiring confirmation for elevated actions.
User Account Control: Switch to the secure desktop when prompting for elevation: Determines whether the UAC prompt displays on the user's standard or secure desktop.
