在通过任务管理器(Task Manager)查看不必要的进程时，您可能已经注意到一个名为TrustedInstaller.exe的任务。它通常会显示高CPU使用率，有时会降低您的计算机速度。
在尝试删除某些系统文件(delete some system files)时，您可能还会遇到错误消息，将这些文件的所有权归于名为TrustedInstaller的用户。那么这个TrustedInstaller是什么？它是恶意程序吗？你应该尝试删除它吗？
什么是 TrustedInstaller？
TrustedInstaller是一个Windows系统实用程序。它充当隐藏用户，拥有安装和管理Windows更新的唯一权限。
作为Windows Module Installer的一个子集，它通常用于在后台添加或修改Windows组件。这有时会导致CPU使用率飙升。不过您不必担心，因为一旦安装了Windows更新，您的系统就会恢复正常。
TrustedInstaller显示为用户“拥有”许多系统文件的原因是为了防止篡改它们。像这样受保护的大多数文件都属于系统关键功能，删除它们可能会破坏您的计算机。
应该删除 TrustedInstaller 吗？
TrustedInstaller.exe不是病毒或第三方应用程序，而是一个必不可少的Windows进程。它的存在对于Windows操作系统的正常运行至关重要。
TrustedInstaller不仅是安装Windows更新所必需的，而且还用于删除过时的更新并确保没有冲突。没有它，您最终可能会安装不兼容的模块，从而使您的 PC 无法使用。
如果您只想删除Windows.old文件夹，则无需对TrustedInstaller或文件所有权进行任何更改。您可以使用磁盘清理实用程序轻松删除它(use the Disk Cleanup utility to easily remove it)而没有任何风险。
如何修复 TrustedInstaller
现在，使用TrustedInstaller(TrustedInstaller)可能会遇到两种问题。
首先是您可能无法删除某些系统文件。此限制是一项功能，可保护重要文件免受意外更改。不过，如果您知道自己在做什么，则可以通过获取TrustedInstaller 拥有的文件(delete files owned by TrustedInstaller)的所有权来删除它们。请注意，删除错误的文件很容易损坏您的Windows安装。
您可能面临的第二个问题是高CPU使用率。如果尖峰是暂时的，那么这不是问题。通常，TrustedInstaller.exe在安装(TrustedInstaller.exe)Windows更新时会占用更多系统资源。一段时间后使用应恢复正常。
如果CPU使用率一直居高不下，那么您可能会面临损坏的TrustedInstaller模块甚至病毒。
在任务管理器(Task Manager)中验证TrustedInstaller 进程(TrustedInstaller Process)
- 要打开任务管理器(Task Manager)，请右键单击任务栏(Taskbar)，然后从弹出的菜单中选择任务管理器。(Task Manager )
- 如果这是您第一次在计算机上打开任务管理器(Task Manager)，它将仅显示正在运行的程序。单击(Click)更多详细信息(More details)以获取完整视图。
- 任务管理器(Task Manager)的默认选项卡是进程(Processes)。在这里，您可以查看计算机上所有当前正在运行的进程，包括系统所有进程和其他进程。如果TrustedInstaller正在使用大量CPU，它将自动显示在顶部附近。
- 但如果不是这种情况，定位过程可能有点困难。查找它的最佳位置是在“服务(Services)”选项卡中。
- 由于列表按字母顺序排序，因此键入“t”以用于以该字母开头的所有进程。找到TrustedInstaller后，您将能够看到其状态以及相关信息。
- 这本身就证明它是一个Windows服务。但是，如果您在“服务(Services)”选项卡中发现 CPU 使用率较高的进程，请右键单击它并选择“转到详细信息”。(Go to details. )这允许您再次右键单击以显示其Properties。
- 属性(Properties)窗口将打开。首先要检查的是它的位置。对于真正的TrustedInstaller应用程序，这应该是C:\Windows\servicing。如果不是这种情况，那么您可能正在处理恶意软件。
- 如需进一步确认，请切换到数字签名(Digital Signatures )选项卡。这显示文件是否已签名，以及由谁签名。如果签名显示Microsoft Windows，那么这确实是真正的TrustedInstaller。
如果您发现TrustedInstaller.exe不是真的，那么它可能是病毒。您应该使用防病毒软件(antivirus software)扫描您的计算机以将其删除。
(Repair TrustedInstaller)使用系统文件检查(System File Check)修复 TrustedInstaller
系统文件检查(System File Check)( SFC ) 是一个命令提示实用程序，可扫描您的Windows安装以查找错误并进行修复。这是修复任何损坏的 Windows 组件(a great way to fix any corrupted Windows components)（包括 TrustedInstaller）的好方法。
- 要使用SFC实用程序，您必须以管理员身份打开命令提示符。(Command Prompt)在搜索栏中键入“(Type “) cmd”以找到该应用并选择以管理员身份运行。(Run as administrator.)
- 命令提示符(Command Prompt)窗口将打开。输入sfc /scannow 以扫描您的Windows文件以查找错误。
- SFC将开始扫描您的文件，验证每个Windows组件的完整性。如果发现任何错误，它们也会自动修复。
TrustedInstaller是恶意程序(Program)吗？
虽然删除不必要的应用程序总是一个好主意，但TrustedInstaller是Windows操作系统的重要组成部分。负责安装重要的Windows更新，删除它会对您的计算机产生不利影响。
话虽如此，并不是每个自称为TrustedInstaller的应用程序都是真实的。病毒有时会隐藏在名称下，因此建议验证该进程是否实际上源自Windows服务。
如果您仍然遇到TrustedInstaller的问题，您应该使用系统文件检查(System File Check)实用程序来修复您的Windows 文件(files)。这将替换任何损坏的文件(files)，让TrustedInstaller再次顺利运行。
What Is TrustedInstaller and Is It Safe?
While looking through Task Manager for unnecessary processeѕ, you may hаνe noticed a task сalled TrustedInstaller.exe. It can often show high CPU usagе, ѕlowing down yоυr computer at times.
You may have also encountered an error message when trying to delete some system files, attributing the ownership of those files to a user called TrustedInstaller. So what is this TrustedInstaller? Is it a malicious program? Should you try to remove it?
What Is TrustedInstaller?
TrustedInstaller is a Windows system utility. It functions as a hidden user, with the sole privilege to install and manage Windows updates.
As a subset of the Windows Module Installer, it is often used to add or modify Windows components in the background. This can sometimes cause the CPU usage to spike. You shouldn’t worry though, as your system will return to normal once the Windows updates have been installed.
The reason TrustedInstaller is shown as the user “owning” many system files is to prevent tampering with them. Most of the files protected like this belong to system-critical functions, and removing them can destabilize your computer.
Should TrustedInstaller Be Deleted?
TrustedInstaller.exe is not a virus or a third-party application, but rather an essential Windows process. Its presence is crucial for the proper functioning of the Windows operating system.
Not only is TrustedInstaller necessary for installing Windows updates, but it is also used to remove outdated updates and ensure that there are no conflicts. Without it, you may end up installing incompatible modules that make your PC unusable.
If you are looking to just remove the Windows.old folder, then you don’t need to make any changes to TrustedInstaller or file ownership. You can use the Disk Cleanup utility to easily remove it without any risk.
How to Fix TrustedInstaller
Now, there are two kinds of problems you might face with TrustedInstaller.
The first is that you might be unable to delete certain system files. This restriction is a feature and safeguards important files from accidental changes. Still, if you know what you are doing, you can delete files owned by TrustedInstaller by taking ownership of them. Be warned that deleting the wrong files can easily damage your Windows installation.
The second problem you might be facing is high CPU usage. If the spikes are temporary, then this is not an issue. Usually, TrustedInstaller.exe takes up more system resources while it is installing a Windows update. The usage should return to normal after some time.
In case the CPU usage remains consistently high all the time, then you might be facing a corrupted TrustedInstaller module or even a virus.
Verifying the TrustedInstaller Process in Task Manager
- To open Task Manager, right-click on the Taskbar and select Task Manager from the menu that pops up.
- If this is your first time opening Task Manager on your computer, it will display only running programs. Click on More details to get the complete view.
- The default tab of the Task Manager is Processes. Here you can see all the currently running processes on your computer, both system owned and otherwise. If TrustedInstaller is using up a lot of CPU, it will automatically show up near the top.
- But when that is not the case, it can be a bit hard to locate the process. The best place to look for it is in the Services tab.
- As the list is sorted alphabetically, type “t” to be taken to all processes starting with that letter. Once you find TrustedInstaller, you will be able to see its status as well as related information.
- This by itself proves that it is a Windows service. But in case you found the process with high-CPU usage in the Services tab, right-click on it and select Go to details. This allows you to right-click again to bring up its Properties.
- The Properties window will open up. The first thing to check is its location. For the genuine TrustedInstaller application, this should be C:\Windows\servicing. If that’s not the case, then you are probably dealing with malware.
- For further confirmation, switch to the Digital Signatures tab. This shows if the file has been signed, and by whom. If the signature shows Microsoft Windows, then this indeed is the real TrustedInstaller.
If you find that TrustedInstaller.exe is not the real deal, then it can be a virus. You should scan your computer with antivirus software to remove it.
Repair TrustedInstaller with System File Check
System File Check (SFC) is a command prompt utility that scans your Windows installation for errors and repairs it. It is a great way to fix any corrupted Windows components, including the TrustedInstaller.
- To use the SFC utility, you must open Command Prompt as an administrator. Type “cmd” in the search bar to find the app and select Run as administrator.
- The Command Prompt window will open up. Enter sfc /scannow to scan your Windows files for errors.
- SFC will begin scanning your files, verifying the integrity of each Windows component. If any errors are found, they will automatically be fixed as well.
Is TrustedInstaller a Malicious Program?
While it is always a good idea to remove unnecessary applications, TrustedInstaller is an essential part of the Windows operating system. Tasked with the installation of critical Windows updates, removing it would adversely affect your computer.
That being said, not every application calling itself TrustedInstaller is real. Viruses can sometimes hide under the name, so it is advised to verify whether the process actually originates from a Windows service or not.
In case you are still having issues with TrustedInstaller, you should use the System File Check utility to repair your Windows files. This will replace any corrupted files, allowing TrustedInstaller to function smoothly again.
