01. How to Delete files protected by Windows 7 Trusted Installers?

Problem

I just find that a lot of files in windows 7 are not owned by me, even if I am the Administrator. They are instead owned by an entity called the "Trusted Installer". I know this may be files protected by windows 7, but I want to be the owner of all files, so I hope to delete files protected by windows 7 trusted installers, but the problem is how to do that

Solution

1. Go to C:\Windows\System32 that you need to change permissions, and the right click to choose "Properties".
2. Click on the Security tab and then click on "Advanced" button.
3. Click on the Owner tab and you will see the current owner is TrustedInstaller.
4. Click on the "Edit" button.
5. Choose who you would like to change the owner to. If your account is an Administrator account, I would suggest just choose "Administrators".Uncheck "Replace owner on subcontainers and objects".
7. Click "OK" until you have closed all properties windows and are back to the Windows Explorer screen. Then right click on the file again and choose "Properties".
8. Click on the Security tab again, and click the "Edit" button.
9. Click on the user name that you want to change the permissions for, which should be the same as who you changed the current owner too, and check on the box next to "Full Control".
10. Click "OK", now you have deleted protected by Windows 7 Trusted Installers.
