Via the Run command in Windows, you can use certain pre-defined commands to open up applications. In fact in Windows 7 & Vista, its Start Menu Search box itself acts as a Run box. If you type the name of an application, say Ultimate Windows Tweaker (uwt) in the start box, it will search for the app and display it in the results. Hitting Enter will open the app.
But typing it in the Run box will not open it. With the help of this tip you can open any software or application via the Windows Run box. That is, you can create your own custom commands. And there are 2 ways to do it. (1) The Easy way and (2) The Not-so-easy way.
(1) The Easy way:
Create a shortcut of the application or program. Rename it to any short name, like uwt, and place this shortcut in the Windows folder. Now type uwt in start search box and hit Enter, and you will see the Tweaker start! To reconfirm, open the Run box and type uwt and hit enter. The Tweaker opens! I have also tried it with a folder and it works! I created a shortcut of my oft used folder, renamed it to f1 and saved the shortcut in the Windows folder. Typing f1 in start search box or in the Run box will open the folder!
(2) The Not-so-easy way.
Open regedit and navigate to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths
In the left panel, right click this App Paths key and choose New > Key. Name it as uwt.exe (I am using UWT as an example). Dont forget to add the file types. Now in the right panel, double click on the Default string value and in the Value and in the box which opens, enter the path of the executable ie E:\Program Files\UWTv2.0\Ultimate Windows Tweaker.exe. My Windows 7 is installed in E drive; hence shows ‘E’ here.
Again in the right side, empty spot, right click > select New > String Value. Name the key as Path. Double click and give it the value as the folder path, ie in this example: E:\Program Files\UWTv2.0\
Exit regedit.
Now type uwt in Start Search Box (or the Run box) and hit Enter, and you will see the Tweaker start! You can start any file type this way.
