Hi

I guess all the programs that ship with windows works with RUN in this way.
Let me state more precisely, just for the sake of order:

An executable can be executed with RUN, if it's location (the folder)
is in the %PATH% environment variable[1]. Check the %PATH%
variable via "echo %PATH%" in the command prompt.


Cheers
