How many clicks I need to delete a file owned by "TrustedInstaller"

If you have the problem with this crap Vista based Windows Server 2008 that you want to delete a file owned by "TrustedInstaller", how many clicks do you need?

1.) Right Click on the file
2.) Left Click on "Properties"
3.) Left Click "Security Tab"
4.) Left Click "Advanced" Button
5.) Left Click "Owner" Tab
6.) Left Click "Edit" Button
7.) Left Click UAC "Continue" Button
8.) Left Click "Administrators"
9.) Left Click "OK" Button
10.) Left Click "OK" Button of Security Dialog
11.) Left Click "OK" Button

Thanks god there are a few commandline utilities that do the job just as expected:

start an elevated "cmd"

Use:

takeown /f <FileOrDirectory> /r /a
icacls <FileOrDirectory> /grant administrators:F /t
