Windows 10 is made up of hundreds of components, all coming together to provide a good user experience. However, in some cases, these components may seem more of a headache than a blessing. Recently, many came online to share their experiences and report issues with a component called TrustedInstaller.
Many users have expressed their frustrations with the TrustedInstaller not allowing them to delete or modify files in some system locations. In some cases, TrustedInstaller uses high CPU resources and slows down the computer.
In this post, you’ll learn what the TrustedInstaller is and how to fix or remove the TrustedInstaller in Windows 10.
The TrustedInstaller is a Windows Modules Installer component, responsible for helping you install, modify and remove updates and other Windows components. It’s essentially a built-in, hidden “user account” in Windows 10, as well as Windows 8 and Windows 7.
It “owns” some of your system files, such as various files in your Program Files folder, and your Windows folder. This, in and of itself, doesn’t cause many issues, but some users have been fed up with the component blocking them from editing or deleting some folders and files.
For example, when trying to rename a folder, you may come across the following error: “You require permission from TrustedInstaller to make changes to this folder”. You might think that there’s nothing you can do to fix this, as TrustedInstaller is not a real user. However, we have some workarounds and methods to help you.
No, you shouldn’t remove TrustedInstaller under any circumstances. TrustedInstaller is not malware, and it can’t harm your computer other than causing CPU consumption.
It’s a necessary part of your operating system, responsible for handling complex operations within Windows 10. Without it, your system will end up corrupted, often beyond repair. If someone tells you to delete the TrustedInstaller, don’t listen to their instructions.
If you require access to system files, instead of removing the TrustedInstaller, you can take ownership of files and folders. This is a completely safe way of bypassing the TrustedInstaller protection, as long as you stay mindful of what files you can and can’t modify.
While the TrustedInstaller account owns your system files, it's possible to regain ownership of them if you want to modify them. Take into account that the module often prevents you from causing issues. For example, if you rename the System32 folder, your operating system will stop working. TrustedInstaller blocks you from renaming this folder in order to prevent damage.
Warning: Only proceed with these steps if you’re an advanced user and know what you’re doing. We highly recommend creating a system restore point and backing up important files before modifying any system folder.
Repeat these steps for any more folders and/or files you want to modify. You should be able to edit and delete system files now. If you feel that you often need to repeat these steps, we highly recommend looking into downloading a .reg file that adds the “Take Ownership” option to your right-click context menu.
In some cases, the TrustedInstaller service or account may become corrupted. This can lead to many issues, especially because the account is tied to system files. If you think that the TrustedInstaller is using too much CPU or it has been corrupted, follow the methods below to fix it.
These corruptions can be caused by abrupt shutdowns, a new Windows Update, or malware infections. To ensure your files are safe, use an antivirus app like Kaspersky Anti-virus 2021.
The System File Checker (SFC) is a troubleshooting tool available in Windows 10 by default. It’s able to automatically detect corrupted system files, and repair them to working order. You can use the SFC scan to potentially fix any corruption with the TrustedInstaller account.
The TrustedInstaller should function as intended now. If you still experience high CPU usage or any similar issues tied to the module, continue reading.
If you feel that your system is functioning poorly and the System File Checker isn’t able to help, we recommend rolling back to a restore point. If you or your system created a suitable restore point, you’ll be able to return to it and continue using your computer with the settings at that time. This could fix TrustedInstaller corruptions.
After completing the restoration process, check if TrustedInstaller is still causing high CPU usage. Don’t see an improvement? Continue reading to ensure your system isn’t infected with malicious malware.
While highly unlikely, there is a small chance that TrustedInstaller.exe is infected with malware, or it was replaced by malicious software. If you want to stay safe, we recommend running a full system scan for malware.
We’ll be using the built-in Windows Defender to conduct a system scan, however, a more focused third-party antivirus solution may work better.
