Much faster than Laszlo’s build for me. Went from 600-700khash/s to 1000-1100khash/s on my Intel Core 2 Duo E8500. From 700-800khash/s on a laptop i7 to ~1100khash/s.
edit: Keeping the “Run Bitcoin” option checked in the installer seems to run it with admin privileges on the first launch. (in Win7)
