Does that downloadsquad linked utility take care of all the work that previously would have required BartPE and a bunch of different recipes? Last summer I built a bootable XP stick, and it was a huge PITA (and in the end it was still a subset of what I wanted).

Compared to the Linux-based USB-bootable Live images, my Windows experience was terrible. Still, I need a Windows environment to get into my corporate network, and having an emergency boot-in-joe-random-PC stick would be nice.
