Start>Programs>Admin Tools... why do properties vary and what is /s?

Greetings, new member and total noob here.
I'm running Win 7 Ultimate on a 32 bit Lenovo laptop.
So I was playing around with the Admin Tools found by pressing Start>Programs>Admin Tools.

I noticed if I right click and select the properties of these items, they seem to point to a different "directory". I've attached screenshots of the Computer Management and Firewall properties as examples. You can see Firewall starts in %windir% and Computer Management starts in %HOMEDRIVE%%HOMEPATH%.

Can anyone please explain this. Sorry if this is basic stuff but I searched and my bad googling skills couldn't find much info. Also, why is there a space with an "/s" after the "compmgmt.msc" in the Target field of the Computer Management?

I also discovered the "Local Security Policy" and thought it was interesting my Firewall says it's not configured but if I go to the Firewall via the Control panel it says it's turned on.
