Run command prompt as "Administrator"

If you use command prompts (say to use Route Add) you may find the system wont comply because the command needs to be 'Elevated'.

In other words run as admin.  The simplest way to do this is to run the whole shell as Administrator.

In the Start menu search box type cmd (wont work from run) which will list up any commands begining with cmd.
Right click cmd and select "Run as administrator"
