Run msconfig from Start Menu->Run.  Under the "Environment" tab of the 
program that opens, there is a variable called PATH.  The value of path 
is a semicolon delimited list of directories.  Add C:\RUBY\BIN (or 
whatever directory holds ruby.exe on your computer) to the PATH variable 
and apply the changes. You might have to restart, but you won't have to 
type the full path to ruby ever again!
