Taking Ownership from TrustedInstaller

Have you ever encountered an error message that says “Access denied” when trying to delete or modify certain system files or folders on your Windows PC? This can be frustrating, especially when you are the administrator of your own computer. The reason behind this is that these files or folders are deemed to be owned by the TrustedInstaller account, an essential and protected system account in Windows.

What is TrustedInstaller?

TrustedInstaller is a built-in user account in Windows, introduced in Windows Vista and still present in the latest version of Windows 10. This account is used by Windows to manage the installation, removal, and modification of system files and folders. It is responsible for maintaining the integrity and security of the operating system and prevents unauthorized changes.

Why can’t you modify files owned by TrustedInstaller?

As a security measure, Windows only allows the TrustedInstaller account to have full control over certain system files and folders. This prevents any malicious software or unauthorized users from modifying critical system files and potentially harming your computer.

How to take ownership from TrustedInstaller?

While it is important to have TrustedInstaller control over system files, there may be times when you need to modify or delete these files for troubleshooting purposes or to install certain software. To do so, you will need to take ownership of the files or folders. Here’s how:

1. Right-click on the file or folder that you want to modify or delete and select “Properties.”

2. In the Properties window, click on the “Security” tab.

3. Click on the “Advanced” button in the bottom right corner.

4. In the Advanced Security Settings window, click on the “Change” link next to the owner’s name.

5. In the window that opens, enter your Windows account username in the “Enter the object name to select” field and click on “Check Names.” This will verify the username and add it to the field.

6. Click on “OK” and the new owner will be added to the list.

7. Check the box next to “Replace owner on subcontainers and objects” and click “Apply” and then “OK.”

8. You will be prompted with a security warning, click “Yes” to continue.

9. You should now have taken ownership of the file or folder from TrustedInstaller.

10. To confirm, go back to the Security tab in the Properties window and click on “Advanced” again. Your Windows username should now be listed as the owner.

From here, you can modify or delete the file or folder as needed. Once you are done, it is recommended to change the owner back to TrustedInstaller for security purposes. Simply repeat the steps above but choose “TrustedInstaller” as the owner in the “Enter the object name to select” field.

In conclusion, taking ownership from TrustedInstaller is a simple process that allows you to have control over system files and folders on your Windows PC. It is important to exercise caution when modifying these files and always change the owner back to TrustedInstaller once you are done.
