    Change User Account Control (UAC) Settings in Windows 10

    How to Change User Account Control (UAC) Settings in Windows 10


    User Account Control (UAC) helps prevent malware from damaging a computer and helps organizations deploy a better-managed desktop environment. With UAC, apps and tasks always run in the security context of a non-administrator account, unless an administrator specifically authorizes administrator-level access to the system. UAC can block the automatic installation of unauthorized apps and prevent inadvertent changes to system settings.

    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.

    UAC allows all users to log on to their computers using a standard user account. Processes launched using a standard user token may perform tasks using access rights granted to a standard user. For instance, File Explorer automatically inherits standard user level permissions. Additionally, any apps that are started using File Explorer (for example, by double-clicking a shortcut) also run with the standard set of user permissions. Many apps, including those that are included with the operating system itself, are designed to work properly in this way.

    Other apps, especially those that were not specifically designed with security settings in mind, often require additional permissions to run successfully. These types of apps are referred to as legacy apps. Additionally, actions such as installing new software and making configuration changes to the Windows Firewall, require more permissions than what is available to a standard user account.

    When an app needs to run with more than standard user rights, UAC can restore additional user groups to the token. This enables the user to have explicit control of apps that are making system level changes to their computer or device.

    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 (UAC).

    When UAC is enabled, 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 credential prompt.

    Reference: User Account Control (Windows 10)

    By default, UAC is set to notify you whenever apps try to make changes to your PC, but you can change how often UAC notifies you.

    In Windows 10, User Account Control has added some improvements.
    • Integration with the Antimalware Scan Interface (AMSI). The AMSI scans all UAC elevation requests for malware. If malware is detected, the admin privilege is blocked.
    When you are prompted to enter your credentials or elevate a program starting with Windows 10 Insider Preview Build 14328, you will notice the dialog now has a fresh and modern UI to align with the design language in use across Windows 10. And now when prompted to enter credentials, you can choose to sign-in with Windows Hello, a PIN, certificates or a simple password.

    This table describes each UAC setting and how it can impact your PC's security.

    [table][tr][td]Setting[/td] [td]Description[/td] [td]Security impact[/td] [/tr] [tr][td][/td] [td][/td] [td][/td] [/tr] [tr][td]Always notify me (recommended)[/td] [td]
    • You'll be notified before apps make changes to your PC or to Windows settings that require administrator permissions.
    • When you're notified, your screen will be dimmed, and you must either approve or deny the request in the UAC dialog box before you can do anything else on your PC.
    [/td] [td]
    • This is the most secure setting.
    • When you're notified, you should carefully read the contents of each dialog box before allowing changes to be made to your PC.
    • Standard users will be prompted to enter an administrator's password to approve.
    [/td] [/tr] [tr][td][/td] [td][/td] [td][/td] [/tr] [tr][td]Notify me only when apps try to make changes to my computer (default)[/td] [td]
    • You'll be notified before apps make changes to your PC that require administrator permissions.
    • You'll be notified if an app tries to make changes to a Windows setting.
    • You won't be notified if you try to make changes to Windows settings that require administrator permissions.
    [/td] [td]
    • It's usually safe to allow changes to be made to Windows settings without you being notified. However, certain apps that come with Windows can have commands or data passed to them, and malicious software can take advantage of this by using these apps to install files or change settings on your PC. You should always be careful about which apps you allow to run on your PC.
    • Standard users will be prompted to enter an administrator's password to approve.
    [/td] [/tr] [tr][td][/td] [td][/td] [td][/td] [/tr] [tr][td]Notify me only when apps try to make changes to my computer (don't dim my desktop)[/td] [td]
    • You'll be notified before apps make changes to your PC that require administrator permissions.
    • You'll be notified if an app tries to make changes to a Windows setting.
    • You won't be notified if you try to make changes to Windows settings that require administrator permissions.
    [/td] [td]
    • This setting is the same as "Notify me only when apps try to make changes to my computer," but your desktop won't get dimmed.
    • If you choose this option, other apps might be able to interfere with the visual appearance of the UAC dialog box. This is a security risk, especially if there's malware on your PC.
    • Standard users will be prompted to enter an administrator's password to approve.
    [/td] [/tr] [tr][td][/td] [td][/td] [td][/td] [/tr] [tr][td]Never notify me (turn off UAC)[/td] [td]
    • You won't be notified before any changes are made to your PC.
    • If you're signed in as an administrator, apps can make changes to your PC without your knowledge.
    • If you're signed in as a standard user, any changes that require administrator permissions will automatically be denied, or still be prompted by UAC.
    [/td] [td]
    • This is the least secure setting. When you set UAC to never notify, you open up your PC to potential security risks.
    • If you set UAC to never notify, you should be careful about which apps you run, because they'll have the same access to the PC as you do. This includes reading and making changes to protected system areas, your personal data, saved files, and anything else stored on the PC. Apps will also be able to communicate and transfer info to and from anything your PC connects with, including the Internet.
    [/td] [/tr] [/table]

    This tutorial will show you how to change User Account Control (UAC) settings for when users are to be notified about changes to your computer in Windows 10.

    *Warning You must be signed in as an administrator to be able to change UAC settings.

    Maybe it has to do with the anti malware scan portion of the request?

    It could be an antivirus compatibility issue. Turning the UAC control down one notch only seems to prevent the screen dimming - is that right? If so, I'll leave it on that setting to workaround the issue since I know what I'm doing (hopefully).
