in your command prompt you have to be in the c:\android-sdk-windows\tools\ directory for it to work
Can't you go into the Enviroment Variables and change the class path so you don't have to be in the folder? I think I can figure it out how to change it so I don't have to be in the \tools folder, but I would also like to eliminate having to type "adb-windows" before every command, when I could just type "adb".
