Turns out some people think the run command has disappeared from Vista – it hasn’t. 

The new search bar (in the start panel) will not only search your computer, it will also run any command you type.

However, if you miss seeing the old Run command in your start panel, try this:

Right click on your taskbar; select Properties

Click on the start menu; select customize

Scroll through to the Run Command check box; check it!

Voila
