I overcome this annoyance by creating a desktop shortcut and setting its Properties to "Run as an Administrator".
To create an Admin-level command prompt, go to Start >Programs and open the Accessories folder. Right-click on, and holding down the right-click, use the cursor to drag the black Command Prompt icon to a vacant area on your descktop. Let go and select (click) "Create shortcut here" from the list of choices.
Now you will have a new, black Command Prompt icon. Right-click on your new icon, and select Properties and click on the Shortcut tab. Now click on the "Advanced" button toward the bottom
Place a check in the "Run as Administrator" checkbox, and click the "OK" button twice. That's it!
Now you will be able to accomplish the advanced commands as you expect you should.
