Run a program as administrator from the Search box
As you probably know, you can use the new Search box in the Windows Vista Start Menu the same way you used the Run command in Windows XP (plus, it does a whole lot more). To run a program as an administrator from the Search box, type the command (such as CMD for the command prompt) and then press Ctrl-Shift-Enter.
Run a program as administrator from the graphical interface
You can also run a program as administrator right from a program icon. Instead of double-clicking the program icon to launch it, right-click the icon and choose Run as Administrator from the shortcut menu.
Set a program to always run as administrator
If you have a program that you run frequently, you can set the program to always run as administrator. To do this, use the following steps:
Right-click the program icon and click Properties.
On the Property sheet, click the Compatibility tab.
Under Privilege Level, select the Run this program as an administrator check box, and then click OK.
Bonus Tip: If you work in the command prompt a lot, right-click the Command Prompt shortcut on your Start menu and click Properties. On the property sheet, click Advanced. In the Advanced Properties dialog box that opens, click Run As Administrator. When you use the shortcut to open the command prompt, UAC will prompt you for administrative priveleges.
