TrustedInstaller.exe是一个Windows 模块^{(Windows Module)}服务，它是Windows 资源保护^{(Windows Resource Protection)}( WRP ) 的一个组成部分。这限制了对作为Windows安装一部分的某些核心系统文件、文件夹和注册表项的访问。TrustedInstaller是一个内置用户帐户，拥有访问Windows中文件和文件夹所需的所有权限。

Windows 资源保护 (WRP) 的作用是什么？^{(What is the work of Windows Resource Protection (WRP)?)}

WRP保护扩展名为 .dll、.exe、.oxc和.sys文件的Windows文件不被修改或替换。默认情况下，这些文件扩展名只能由Windows 模块安装程序^{(Windows Module Installer)}服务TrustedInstaller修改或替换。如果您更改或自定义默认TrustedInstaller设置，那么您的系统将面临风险。

有时您需要更改文件的所有权来修改或替换系统文件。尽管如此，一旦您完成了自定义，就无法将权限还给TrustedInstaller，有时这可能会导致系统不稳定，因为它不再可以保护系统核心文件。本指南将向您展示如何使用下面列出的步骤在Windows中将^(Windows)TrustedInstaller恢复为文件所有者。^{(File Owner)}

在Windows 10中将^{(Windows 10)}TrustedInstaller还原为文件所有者^{(File Owner)}

确保 创建一个还原点^{(create a restore point)} 以防万一出现问题。

1.右键单击^{(Right-click)}​​文件、文件夹或注册表^{(Registry Key)}项以将所有权恢复为默认TruestedInstaller，然后单击属性。^{(click Properties.)}

2. 现在切换到安全选项卡^{(security tab)}，然后单击底部附近的高级按钮。^(Advanced)

3. 在高级安全设置^{(Advanced Security Settings)}页面上，单击所有者下的更改。^{( Change under the Owner.)}

4. 接下来，在输入要选择的对象名称下键入“ ^{( Enter the object name to select)}NT Service\TrustedInstaller ”（不带引号），然后单击“检查名称”^{(Check Names)}，然后单击“确定”。

5. 确保选中所有者下的“替换子容器和对象上的^{(Replace owner on the subcontainers and objects)}所有者”，并再次选中底部的“将所有子对象权限条目替换为此对象的可继承权限条目”。^{(Replace all child object permission entries with inheritable permission entries from this object)}

6. 单击应用，然后单击确定。

现在，如果您已向您的用户帐户授予完全控制权限，^{(Full Control to your user account)}那么您还需要删除这些设置，请按照以下步骤操作：

1. 再次右键单击相同的文件、文件夹或注册表项，然后选择属性。^{(Properties.)}

2. 切换到安全选项卡并单击底部附近的高级按钮。^{( the Advanced button)}

3. 现在在高级安全设置页面上，在^{(Advanced Security Settings)}权限^{(Permissions)}条目列表下选择（突出显示）您的帐户。

What is the work of Windows Resource Protection (WRP)?

The WRP protect Windows files with extension .dll, .exe, .oxc and .sys files from being modified or replaced. By default, these files extensions can only be modified or replaced by the Windows Module Installer service, TrustedInstaller. If you change or customize the default TrustedInstaller settings, then you’re putting your system at risk.

Sometimes you need to change the ownership of the file to modify or replace system files. Still, once you are done with the customization, there is no option to give back the permission to TrustedInstaller, and sometimes this may lead to the system being unstable as it no longer can protect the system core files. This guide will show you how to restore TrustedInstaller as File Owner in Windows with the below-listed steps.

6. Click Apply, followed by OK.
