You find that there are a lot of files in your computer or laptop. And then, you want to delete them but it is not successful and indeed there is a notification which says “You need permission from TrustedInstaller to perform this action”. This was made by Windows to protect the users from accidental damage and stop users deleting important file accidentally. But, you can take control over your PC and we can get rid of the statement of TrustedInstaller that appears when you try to delete, move and change the file.
What is actually TrustedInstaller? It is a built-in account of user in Windows Vista, Windows 7, Windows 8, and Windows 10. You can not do anything to specific files even though you log in as administrator. It happens because TrustedInstaller has the ownership to the files. This user account owns a kind of system files like files in your Program Files folder, Windows folder, and the Windows.old folder that is made after upgrading from one version of Windows to another new one. So, If you want to rename, edit or delete the files you have to take the ownership of the files. TrustedInstaller was made and implemented in the system of your PC so that it is in control of all the Window updates and several other optional Windows components. It means it has the ability to intall, modify and remove these. But, this is also a useful feature because it can avoid you from deleting important components or files that you can do by accident or on purpose.
There are two methods to own your file.
- Using CMD. You can open “Command Prompt” as an administrator and then type ‘takeown /f “full path of folder or drive” /R /D Y’. For example, you want to take ownership of the Windows folder, you can type ‘takeown /f “C:\Windows” /R /D Y’. You are able to do the similar way for executable files. For example, ‘takeown /f “C:\Windows\regedit.exe’ will take the ownership of the regedit executable.
- Using Windows Explorer. Beside using CMD as being explained above, using Windows Explorer also can be your choice for solving this problem. To do this process, you have to navigate to the folder or file that you want to control. Then, right click and choose “Properties and the Security” tab. Click the “Advanced” button and “Change” next to “Owner”. Type your name of account into the box and click “Check Names”. If you spelled it precisely, it will become underlined. You can see a list come up depending on how you set up your computer. Choose your username from the list and then click “OK”. Click “OK” twice so that it will return to the “Advanced Security Settings” window. Give a check mark in the box where it says “Replace owner of subcontainers and objects”. After that, click OK and then “Yes” if it is prompted.
So, if you there are files that are owned by TunderInstaller and you want to own it, just try the methods above.
