Essential: Windows resource kit

I don't understand why robocopy has not yet replaced xcopy, perhaps Microsoft thinks it's too complex for windows users. That category of users doesn't use xcopy either. Anyway, this little program is one of my reasons to install the windows resource kit which you can download from Microsoft for free. If you don't need the rest of the kit you could just copy robocopy.exe from another computer, no need for a setup procedure.
