The owner of the system folder in win7 is TrustedInstaller. Sometimes we need to obtain administrator privileges from the folder or file to modify the owner. If you want to change it to TrustedInstaller, we will find that the system folder cannot change the owner to TrustedInstaller again, because the real name of the TrustedInstaller group is nt service \ TrustedInstaller, and the command cannot be completed only by entering TrustedInstaller.
Procedure:
Right-click the folder, open the "properties" dialog box, select the "Security" tab, and click the "advanced" button.
Open the "Advanced Security Settings" window, click "owner" label ", and click" edit ".
Open the "owner" label setting window, and click "other users or groups"
Open the "select user or group" window, enter "nt service \ TrustedInstaller" in the window, and click "OK"
