Are you getting a bit frustrated about not being able to do certain things that administrator should be able to do, like run ipconfig /release, and many other commands and tools, and being prompted left and right just so you can say “yes, go ahead and run the program I, administrator, asked you to run”?
Well, the reason is that by default, Vista has the following local policy enable: User Account Control: Run all administrators in Admin Approval mode. Translation: it runs all users, including administrators, as standard users.
You can, however, change this behavior. One way to do so is to open control panel => Administrative Tools => Local Security Policy and set the “User Account Control: Run all administrators in Admin Approval mode” policy to disabled.
IMPORTANT: Only disable it if you really must! Your system is more secure if you have it enabled. You can always choose “run as administrator” by using right mouse button click option…
NOTE: Changing this setting requires a system reboot.
