Creating Your Own Run Commands
If you are like me, you will use a few
programs very frequently. One way to
make them start faster is to give them
their own Run command:
Win+R to open the Run dialog
Enter %windir% to open the Windows
directory
Alt+F W S to open the File menu, choose
the New menu item, then the Shortcut
menu item
Go through the wizard to create a shortcut
to the desired program
The name you give the shortcut is what
you type in the Run dialog to start the
program

Using Run as a Command Prompt
One of the strengths of the Run command
is its ability to do almost everything the
command line can do. You should note,
however, that if you're running a program
that outputs something and exits, that the
output will only show up for a few seconds
and then disappear.
Take the ipconfig command for example. If
you were to type that into Run, it would
open a command prompt, run the ipconfig
command, and then close because the
command finished running! To fix this, type
cmd into the Run dialog, and then type
ipconfig into the command prompt.
