A. By default the title display name is the location of CMD.EXE, however this can be changed using two methods depending on the situation.

If you currently have a command session and you wish to change its title use the title command,

title <title>
e.g. title John Savill's Command Window

Alternativly if you want to start a new command session from an existing command prompt use the start command

start "<title>"
e.g. start "John Savill's Command Window"
