How to Remove Trustedinstaller Protected Files?

Ever had a problem removing certain files from your computer system? Were you denied permission to access these files even when you were the administrator?

The answer to all these questions lies with Trustedinstaller.exe, the owner of all such files.

You get error messages or denied permission requests from this particular program. So, to remove these files, you first have to obtain ownership of them and then take full control of their rights and permissions.

Note: Do not use these steps to remove any basic Windows program like Internet Explorer or Windows Defender. You will only end up messing with the entire system. This tip is useful only for removing malicious files from your system.

This Method Will Help You Take Control of the Files You Wish to Remove.

1. To do this, the first step is to go to a particular folder and right-click on it. Choose ‘Properties,’ and it is from here that you can change the permissions.

4. Go to the ‘Edit‘ option (it’s the same as the ‘Change‘ button in Windows 10). Here, you can choose the owner, which can either be the Administrator’s group or your account.
