Most administrators use the command prompt to run administrative tasks.
The problem is that if you are using Vista, opening the CMD will not allow you to run
commands as an administrator(unclear to me as to why couldn’t they simply let the UAC
take care of it).
To solve this you could start the CMD using a shortcut with RUNAS, a better solution
though is creating a shortcut for CMD and setting the check box by the ‘Run as administrator’
