User Account Control, or just UAC is a part of the Windows security system which prevents apps from making unwanted changes on your PC. By default, the UAC prompt shows administrative accounts which can be selected by standard users to elevate a program. In Windows 10, you can change this behavior. The UAC prompt can be automatically rejected, or can be set to appear on the secure desktop. By default, the user is prompted for administrator credentials to continue.
Since Windows Vista, Microsoft added a new security feature called User Account Control (UAC). It tries to prevent malicious apps from doing potentially harmful things on your PC. When some software tries to change system-related parts of the Registry or the file system, Windows 10 shows an UAC confirmation dialog, where the user should confirm if he really wants to make those changes. Usually, the apps that require elevation are related to the management of Windows or your computer in general. A good example would be the Registry Editor app.
The UAC comes with different security levels. When its options are set to Always notify or Default, your Desktop will be dimmed. The session will be temporary switched to the secure Desktop without open windows and icons, containing only an elevation prompt by the User Account Control (UAC).
Members of the Administrators user group have to confirm or reject the UAC prompt without providing extra credentials (UAC consent prompt). Users without administrative privileges have to additionally enter valid credentials for a local administrator account (UAC credential prompt).
There is a special security policy in Windows 10 that allows changing the UAC prompt behavior for standard users. Let's see how it can be done.
If you are running Windows 10 Pro, Enterprise, or Education edition, you can use the Local Security Policy app to change the policy. All editions of Windows 10, including Windows 10 Home, can use a Registry tweak mentioned below.
To Change UAC Prompt Behavior for Standard Users in Windows 10,
- Press Win + R keys together on your keyboard and type:
- Local Security Policy will open. Go to User Local Policies -> Security Options.
- On the right, scroll to the option User Account Control: Behavior of the elevation prompt for standard users.
- Double-click on this policy to change its value.
- Select the UAC behavior you want to set for standard user accounts.
If your Windows edition doesn't include the secpol.msc tool, you can apply a Registry tweak as described below.
Enable UAC Prompt for Built-in Administrator with a Registry Tweak
- Open Registry Editor.
- Go to the following Registry key:
If you do not have such a key, then just create it.
- Here, modify or create a new 32-bit DWORD value ConsentPromptBehaviorUser. Note: Even if you are running 64-bit Windows you must still create a 32-bit DWORD value. Set its value data to one the following values:
- 0 - Automatically deny elevation requests
- 1 - Prompt for credentials on the secure desktop
- 3 - Prompt for credentials (set by default)
- Restart Windows 10.
