hh.exe can open drive C when trying old dos '/?' Command!...
First off.. this isn't a problem for me, Not asking for help just sharing something I've found that seems strange.
This is ONLY tested on build 7201 x64 because I only just found it so I cant vouche for other builds.
I set out on a mission earlier to try and open a certain help page from the command-line and stumbled across this strange little 'bug'.
What I found is that typing "hh.exe /?" into the run dialog opens the system drive in a help window.
I realise that it's probably no more a threat than opening any folder on your own PC the normal way but having said that, I'm no security expert!
This tickled me slightly so just wanted to share the info.
My system was upgraded to this build so could be left-over from previous ones.
