    On my system, I have Recovery Console installed on the hard drive (so I don't have to use my XP install CD to run the RC.)  I have that file in the folder: C:\Cmdcons, where the Recovery Console is loaded.  If I do a right click on the file, select Properties from the context menu that scrolls out, and then look on the Version tab, this is what it says:

    Windows NT Setup mini command console

    In addition, a google search for me turned up this page, which, admittedly, is on Win2k, but I would bet the discussion applies to XP too:
    Inside Win2K Reliablity Enhancements, Part 1

    Here's a quotation from that page:

    When you run the RC, Session Manager loads and starts two device drivers that implement the RC: spcmdcon.sys and setupdd.sys. Setupdd.sys is a support driver that gives spcmdcon.sys a set of functions that let spcmdcon.sys manage disk partitions, load Registry hives, and display and manage video output. Setupdd.sys communicates with disk drivers to manage disk partitions and uses basic video support built in the Win2K kernel to display messages on the screen.
