I installed RT Seven Lite Software for making my own Windows 7 custom ISO. I loaded official Windows 7 ISO into RT Seven lite and started editing, But for some reason i stopped working on that. The problems is i uninstalled RT Seven Lite and i thought the windows files i was working on will be delete automatically but this didn't happened. Now i have left over windows 7 setup files that i can't delete. When i delete files it gives error '' You require permission from administrators to make changes to this file/folders''. But i am on administrative account.
And even if i try to change ownership of files/folders the options are not accessible. Only Trustedinstaller have full control on files. (My English is not good so please watch video to understand my problem)

I even tried to use Linux Fedora OS to delete those files but still failed. Those files took 32GB size on my HardDrive. I don't want to format my drive.Help please
