How to Enable or Disable Ctrl+Alt+Delete Secure Desktop for UAC prompt in Windows


When User Account Control (UAC) is enabled, Windows prompts for consent or prompts for credentials of a valid local administrator account before starting a program or task that requires a full administrator access token. This prompt ensures that no malicious software can be silently installed or run.

With the Always notify or Default UAC setting enabled, your desktop will be switched to the dimmed secure desktop when you get an elevation request by the User Account Control (UAC) prompt.

A user that is a member of the Administrators group can log on, browse the Web, and read e-mail while using a standard user access token. When the administrator needs to perform a task that requires the administrator access token, Windows 10 automatically prompts the user for Y/N approval. This prompt is called an elevation prompt for UAC consent prompt.

The user experience for standard users is different from that of administrators in Admin Approval Mode. The recommended and more secure method of running Windows 10 is to make your primary user account a standard user account. Running as a standard user helps to maximize security for a managed environment. With the built-in UAC elevation component, standard users can easily perform an administrative task by entering valid credentials for a local administrator account. The default, built-in UAC elevation component for standard users is the UAC credential prompt.

If you like, you can enable a policy that requires users to press Ctrl+Alt+Delete when prompted by UAC to provide consent (administrators) or credentials (standard users) on the Secure Desktop by means of the trusted path mechanism for better security. This can prevent a Trojan horse or other types of malicious code from stealing the userís Windows credentials.

This tutorial will show you how to enable or disable requiring Ctrl+Alt+Delete Secure Desktop (aka: authentic Windows sign-in screen) for User Account Control (UAC) prompt for all users in Windows 7, Windows 8, or Windows 10.
