Windows Modules Installer: How to deactivate TrustedInstaller in Windows

TrustedInstaller is a legitimate Windows account that runs in the background and is responsible for various system files. TrustedInstaller.exe is an inbuilt user account used for all versions of Windows starting from Windows Vista. Users would not even notice its presence most of the time. However, if malware replaced the mentioned file, it can cause problems. Nevertheless, you might see the following message if you try to modify or delete some specific files or folders in your PC as discussed here.

TrustedInstaller.exe is a process that belongs to Windows Modules Installer and one of the core components of the Windows Resource Protection as described in the first paragraph. Windows Modules Installer’s main purpose is to install and modify Windows updates and other optional system components with a high impact on your computer.

The TrustedInstaller can be also be found under the services.msc
– Launch Windows Services as shown below

Right-click on the “Windows Modules Installer “.
