This probably is not new to many, but I find it useful.
There are times I want an elevated command prompt. I usually type in "cmd", right click on it and run as administrator. If you need an elevated command prompt now and then, simply create a shortcut to "cmd". Right click on the shortcut, left click on properties. Click the shortcut tab and select "advanced". Finally, you can select "run as administrator".
Like I said, just something I didn't think about before, but it's handy to have.
