How to Enable or Disable User Account Control (UAC) prompt for Built-in Administrator 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 dimmed and switched to the 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.

The built-in Administrator account does not get the UAC consent prompt since it runs with full administrative privilege (elevated rights) by default.

If you like, you can set a local security policy that controls whether the built-in Administrator account will be prompted by UAC just like any other administrator account.

This tutorial will show you how to enable or disable User Account Control (UAC) for the built-in Administrator account in Windows 7, Windows 8, or Windows 10.

You must be signed in as an administrator to enable or disable User Account Control (UAC) for the built-in Administrator account.
