Hello,
TrustedInstaller.exe is located at C:\Windows\servicing\ and its normal startup of this service is set at Manual, and it runs under the Local System Account. It has no dependencies.
At times you may find that TrustedInstaller.exe has been corrupted, and you may bet an error message to that effect. In such a case running the System File Checker may help. But sometimes even the Windows Resource Protection service, which runs the system file checker is affected. In such a case if you try to run sfc /scannow, you may get the error message – Windows Resource Protection could not start the repair service.
In such a case you may have to Reset Windows 10.
What happens if you delete TrustedInstaller?
If you change TrustedInstaller settings, you put your system at risk and your system may not function properly. It’s not suggested to remove it. However, if you still want to disable it, you can try to disable User Account Control (UAC) which uses the Trusted Installer account.
It is highly recommended not to delete TrustedInstaller from your computer as long as you want to continue getting the same options and features in the future. Answering the question, yes, you can delete TrustedInstaller.exe, but it will come with some consequences that might damage the system you are using.
You can disable TrustedInstaller or Windows Modules Installer using the Services, which is included in your Windows 11/10 computer. For that, open the Services panel and double-click on the Windows Modules Installer setting. Choose the Disabled option from the Startup type drop-down list and click the OK button. It will disable the TrustedInstaller service on your computer.
