但它有什么作用？WDAGUtilityAccount是什么？继续阅读以了解此用户帐户是什么以及您是否可以将其删除。
什么是 WDAGUtilityAccount
WDAGUtilityAccount是一个内置的用户帐户。它是Windows Defender 应用程序防护(Application Guard)( WDAG ) 的一部分，它自 1709 版以来一直是Windows 10的一部分。通常，应用程序防护(Application Guard)在默认情况下处于禁用状态。您可以通过打开命令提示符(Command Prompt)并键入net user命令来找到它。
或者，如果您的计算机在Windows专业(Pro)版上运行，您可以使用计算机管理(Computer Management)工具访问此用户帐户。
1、在Windows(Windows)搜索框中输入“计算机管理”，点击第一个结果，即“计算机管理(Computer Management)”应用。
2. 在应用程序的右侧面板中，转到系统工具(System Tools)>本地用户和组(Local Users and Groups)，然后单击用户(Users)文件夹。您将在此处找到WDAGUtilityAccount用户帐户。
如前所述，此用户帐户由Windows Defender 应用程序防护(Windows Defender Application Guard)工具使用。该工具是Microsoft Edge和Office 365的一部分，用于启用隐私浏览会话(private browsing sessions)。换句话说，您可以打开与桌面完全隔离的浏览器会话。如果您在该会话期间遇到任何恶意软件，它不会到达您系统的其余部分。
该工具会在虚拟化沙箱中打开您正在访问的网站，并且WDAGUtilityAccount充当该基于虚拟化的容器的用户帐户。用户帐户对于Windows 11/10系统的整体安全至关重要。
删除WDAGUtilityAccount或更改(Change)其设置是否安全？(Safe)
由于这是一个系统管理的用户帐户，因此您实际上无法删除它。即使你可以，你也不想。这是一个重要的安全元素，可以保护您免受特定的安全威胁。当您删除某些类型的文件时，您可能偶尔会看到该帐户要求管理员权限，但该帐户对您的计算机没有任何负面影响。
也就是说，您可以访问特定设置并在需要时更改它们。
返回到计算机管理(Computer Management)工具并双击WDAGUtilityAccount用户帐户。将打开一个包含各种设置的窗口。
您应该保留默认设置，除非您有明确的理由更改它们。如果帐户被禁用，如上图所示，您应该取消选中“帐户已禁用(Account is disabled)”选项。
您也可以重命名用户帐户，但我们不建议这样做。它将破坏Windows Defender 应用程序防护(Windows Defender Application Guard)工具或阻止某些安全功能正常工作。
从本质上讲，WDAGUtilityAccount是一个无害的系统管理用户帐户，应该单独使用。它不会以任何负面方式影响您的计算机。
启用应用程序防护
如前所述，Application Guard通常默认禁用。这是在Windows 11/10 Pro上启用它的方法。您还可以在支持WDAG的(WDAG)Windows 11/10 Enterprise和其他版本上应用这些步骤。
1. 转到Control Panel > Programs > Programs and Features，然后单击打开或关闭 Windows 功能(Turn Windows features on or off)。
2.滚动(Scroll)功能列表，直到找到 Microsoft Defender Application Guard并选中它旁边的框。
3. 单击确定(OK)按钮并重新启动计算机以使更改生效。
如果您找不到此功能或它灰显，则您的计算机不支持Application Guard或您未运行(Application Guard)Windows 11/10的受支持版本之一，例如Windows 11/10 Pro或Enterprise。如果您使用的是Windows Home版本，请(Windows Home)升级到更高版本的 Windows(Upgrade to a higher edition of Windows)。
What Is Wdagutilityaccount on Windows and How Is It Used?
Did you cоme аcross WDAGUtilityAccount when looking through the list of user accounts? Don’t wоrrу—this specіfic user account is not a virus, and your syѕtem isn’t compromised. It’s рart of most versions of Windowѕ 11/10 Pro, Enterрrise, and Εducation.
But what does it do? What is WDAGUtilityAccount? Read on to learn what this user account is and whether you can remove it.
What Is WDAGUtilityAccount
WDAGUtilityAccount is a built-in user account. It’s part of Windows Defender Application Guard (WDAG), which has been part of Windows 10 since version 1709. Usually, Application Guard is disabled by default. You can find it by opening the Command Prompt and typing the net user command.
Alternatively, if your computer runs on a Pro version of Windows, you can access this user account using the Computer Management tool.
1. Type “computer management” in the Windows search box and click on the first result, which is the Computer Management app.
2. In the right panel of the app, go to System Tools > Local Users and Groups and click on the Users folder. That’s where you’re going to find the WDAGUtilityAccount user account.
As mentioned, this user account is used by the Windows Defender Application Guard tool. This tool is part of Microsoft Edge and Office 365, and it’s used to enable private browsing sessions. In other words, you can open a browser session that is completely isolated from your desktop. If you encounter any malicious software during that session, it won’t reach the rest of your system.
The tool opens the website you’re accessing in a virtualized sandbox, and WDAGUtilityAccount acts as the user account for that virtualization-based container. The user account is essential for the overall security of your Windows 11/10 system.
Is It Safe to Remove WDAGUtilityAccount or Change Its Settings?
Since this is a system-managed user account, you can’t actually delete it. Even if you could, you wouldn’t want to. It’s an important security element that protects you from specific security threats. You might occasionally see the account ask for administrator permission when you delete some types of files, but the account doesn’t have any negative impact on your computer.
That said, you can access specific settings and change them if needed.
Go back to the Computer Management tool and double-click on the WDAGUtilityAccount user account. A window with various settings will open.
You should leave the default settings as they are unless you have an explicit reason to change them. If the account is disabled, like in the image above, you should un-check the Account is disabled option.
You can also rename the user account, but we don’t recommend doing so. It will break the Windows Defender Application Guard tool or prevent certain security features from working correctly.
In essence, WDAGUtilityAccount is a harmless system-managed user account that should be left alone. It doesn’t affect your computer in any negative way.
Enable Application Guard
As mentioned earlier, Application Guard is usually disabled by default. Here’s how you can enable it on Windows 11/10 Pro. You can also apply these steps on Windows 11/10 Enterprise and other versions that support WDAG.
1. Go to Control Panel > Programs > Programs and Features and click on Turn Windows features on or off.
2. Scroll through the list of features until you find Microsoft Defender Application Guard and check the box next to it.
3. Click on the OK button and restart your computer for the changes to take effect.
If you can’t find this feature or it’s grayed out, your computer doesn’t support Application Guard or you aren’t running one of the supported versions of Windows 11/10, such as Windows 11/10 Pro or Enterprise. Upgrade to a higher edition of Windows if you’re using the Windows Home edition.
