What Is Trustedinstaller And How To Disable It In 3 Different Methods


Users of Windows 10, as well as all other versions, starting with the 7th, come across TrustedInstaller. This happens when you edit some system files and try to delete them.

The system reports that you need to request permission from TrustedInstaller for these actions, even if your account is an administrator. Find out what it is, why you need it, and whether you can turn it off.

With the release of the innovative Windows 7 operating system back in 2009, many users who got used to reign supremely in their personal and mobile computers were unpleasantly surprised by the strict controller.

Who periodically gave his hands for trying to delete system folders and files an unprecedented TrustedInstaller process, reliably protected from the encroachments of the system itself. So, what is this “beast” and what difficulties does it cause?

TrustedInstaller – what is it?


This is a special service built into the operating system. It prohibits the editing of most system folders and files, designating itself as their owner.

What is it for? Such a ban on changes protects your computer from incorrect or unfriendly interventions from outside, including viruses. As a rule, the user is faced with this service when she does not allow him to delete any folder.


This service was introduced as a virtual observer, having priorities over the user – a person, even as an administrator. Its direct task is to ensure that the data important for the stable operation of Windows cannot be damaged, deleted, or altered by the user’s carelessness, or a malicious virus attack.

Based on WRP (Windows Resource Protection) technology, it “softly” hints that the great men of Microsoft know better what is better for mere mortals and strongly discourage its shutdown, which means …

Disable methods of TrustedInstaller

To edit or delete a folder that does not allow to change this service, you have to disable it and take the rights yourself, that is, the administrator. We offer you a step by step instructions for disconnecting.

First of all, before you start setting up your computer, you should determine the reason for your desires. Many users of Windows 7, 8, 8.1 and 10 complain about the high load of this service processor, which is clearly seen in the task manager. If you encounter such a problem, you should make sure:

A user launched TrustedInstaller with the name “System,” otherwise – there are not enough viruses onboard, and service outages will be enough, the disks should be checked with independent utilities like Dr. Web Cure It! or Virus Removal Tool “Kaspersky Lab.”

Automatic update of the operating system in the “Update Center” is disabled. Indeed, during this process, TrustedInstaller consumes a sufficiently large amount of resource, is cumbersome and annoying.

But … with high Internet speed, the procedure takes no more than 10 minutes, which, with due patience, does not affect the overall system performance.

Making sure that the previous factors do not affect the desire to get rid of the “severe guard” of the operating system, we proceed to direct actions to disable TrustedInstaller by prudently selecting one of two options — full or partial shutdown for a specific folder or file.

Partial removal method

With an extensive number of actions, this procedure does not seem difficult if we act strictly according to the algorithm:

  1. Select the desired folder (file) for editing; click the right mouse button.
  2. From the context menu that appears, select: “Properties,” “Security,” “Advanced.”
  3. We carefully study the tabs, find the “owner” – click on it and on the “change” button.
  4. Left click on the “Advanced” and “Search.”
  5. From the list of owners, choose an administrator.
  6. We find the inscription “Replace the owner of subcontainers and objects,” mark and confirm the operation.

So, most of the work is done, and you are now the full owner of the data! (You can make a solemn sip of good coffee).

It remains a small matter – to give ourselves all the rights and responsibilities, which we will do next, again strictly following the points:

  1. Let’s return to our old “Properties,” “Security,” “Advanced.”
  2. Now, in the list of users, we find our profile (if necessary, we can ‘add’ it), or a group of administrators.
  3. Mark the line “full access” – confirm the operation.
  4. Mark the line “Replace all records …” and click again in confirmation.
  5. Confirm all remaining windows.

The process is complete, and now, calmly, you can edit the file we need or delete the folder.

Complete removal method


Required to remove TrustedInstaller.exe, which loads the processor from the task manager. Let’s start:

  • Holding the key combination “Ctrl,” “Shift,” “Esc” select the Services tab;
  • Select “Background Intelligent Transfer Service (BITS)” and right-click on the context menu;
  • Click “Stop”;
  • Then, in the same way, turn off the Windows Update process;
  • We are looking for the TrustedInstaller process in the Services tab and disable it manually.


Disable the process TrustedInstaller.exe

TrustedInstaller task manager

It is necessary to disable this process if it loads the processor too much.

To start the disabling process, go to the “Task Manager” tab “Processes.” A glance looks at how much memory eats this process and look at the column “User.”

Windows service applications are launched from “System,” so if you have some other name, you can conclude that this file is infected with a virus. In this case, carefully check the system with an antivirus program. And now directly off.

  • Click “Start”, “Control Panel”, “Administration”, “Services”.
  • Go to the “Windows Update” and click “Stop.”
  • We carry out similar actions with the “Background Intellectual Service.”
  • Hold the Ctrl + Shift + Esc combination and go to the “Services.”
  • We find there a line with a certain name, click on it with the right button, and select “Stop.”  This way the process turns into disable mode.

After such actions, the service application should no longer load the processor. If the impact on the processor continues, it is certainly a virus.

So we figured out what a TrustedInstaller is and how to handle it. If the article helped you or left any questions, write in the comments!

In case you need to know the location of the TrustedInstaller.exe file itself, look for it in the Windows \ servicing \ folder … But it is unlikely that you can do anything with it since it is protected very jealously. We hope that we were useful and added new victories on the digital battlefields for you.
