TrustedInstaller Permissions: How to Add, Delete, or Change System Files
Safety features for your own protection
It’s not uncommon for a Windows user to come across an error that requires special permissions. For example, if you’ve ever tried to delete core system files, you likely came across a Folder Access Denied prompt that reads, “You require permission from TrustedInstaller to make changes to this folder.”
This might make you feel like you’re not in total control, but Microsoft has added the NT SERVICETrustedInstaller account to protect your system.
What is TrustedInstaller?
TrustedInstaller is a core component of Windows Resource Protection that Microsoft introduced with Windows Vista. In addition, theWindows Modules Installerservice uses the TrustedInstaller account to add, remove, or modify Windows updates and other components.
Deleting or modifying files or folders owned by TrustedInstaller may prevent your Windows installation from running properly. Think of it as another safeguard that prevents even an administrator account from deleting core Windows files. However, sometimes you may need to fix or modify corrupt system files, for which you’ll require TrustedInstaller permission.
If you’re confident that what you’re doing is safe, you can take ownership of these files from TrustedInstaller. Nevertheless, it’s always a good practice to create a system restore point, just in case.
Take Ownership from TrustedInstaller
There are two methods of taking ownership from TrustedInstaller.
This is a long, but user-friendly way to gain ownership of a folder.
Performing these steps will give you ownership of the folder, and you will no longer require permission from TrustedInstaller to make changes to it.
If you know how to use the Command Prompt, you can transfer ownership much faster than the previous method.
TAKEOWN /F “C:Program FilesInternet Explorer”
Of course, change the path to the folder you want to transfer ownership for.
You can now go ahead and modify orremove Windows foldersas you please. But always ensure that you don’t remove any critical components that will prevent Windows from functioning properly.
