    Restoring TrustedInstaller ownership


    Long story short, I messed with the ownership of some system files and now Windows won’t boot. SFC and dism both fail. Safe mode won’t boot either. The only thing I can access is the command prompt on the automatic repair screen.

    Is there any way to restore the TrustedInstaller ownership for all system files? I’d rather not have to hard reset and lose my programs for such a small change.

    Restore WindowsApps permissionss to TrustedInstaller

    Initially I got the same error that said “NTService\TrustedInstaller is not from a domain listed in the Select Location dialog box, and is therefore not valid.”

    My problem was the lack of a space in "NT Service\TrustedInstaller."

    I got this solution from a post by Sergey Tkachenko at Restore the TrustedInstaller ownership in Windows 10

    Restore WindowsApps permissionss to TrustedInstaller

    Hi Sakso,

    This Windows apps permission could have happened due to the corrupted or outdated Windows component,
    we suggest that you follow the instructions below to restore or reset the default permission for your folder or file:

    • Open the File Explorer.
    • Browse to the system file you previously changed ownership.
    • Right-click the file, and select Properties.
    • Click on the Security tab.
    • Click the Advanced button.
    • On the "Advanced Security Settings" page, click the Change link on Owner.
    • On the "Select User or Group" page, type the following to add the TrustedInstaller account and click
      Check Names: NTService\TrustedInstaller.
    • Click OK and click Apply.
    • Click OK again to complete the task.

    Update us with the result so we can further assist you.
