Aila ... e-freak .. there is something called Freeware in Windows world too ... And lol by your comment "cracking can take hours" I get it you have tried it too

...
Anyways .. The topic here is the accebility of Linux commands ... @ the author, Linux is derived from Unix .. and those command line switches are legacy from Unix .. Most of the time, these commands are better at handling automated tasks such as installation, logon scripts .. et all .. Which arent such easy to do in GUI based interface .. Thats why you'll notice that there are *many* command line options for Sys admins in new Windows installer ...
