Windows Vista Command-line reference?

Is there some sort of tool or area in Vista that lists all of the commands? XP
had one built into Help and Support.

Thanks

I'm sure you already did this but if I open a CMD in Vista and type
"help" - it lists off a bunch of commands I could use.

That's not what I'm looking for though, I want to reference guide that XP had.
Thank you though.

Ogden, I don't find anything perfectly analogous to this:

http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/n
tcmds_o.mspx?mfr=true

or 

http://technet2.microsoft.com/WindowsServer/en/library/552ed70a-208d-48c4-8da8-2
e27b530eac71033.mspx?mfr=true

which you can reach through Help and Support, searching on cmd and selecting
Command-line reference for IT Pros .

I've found these adequate for most purposes, although I'd do a search for new
material in O'Reilly's Safari Books Online.

Have you looked at PowerShell since the beginning of the month?
