It's "Bliss" from Windows XP, just grab it off one of your WinXP machines.
I am embarrassed to say I only have one laptop on XP at the moment, although MOST of the machines using Q4OS have that desktop selected. I have a soft spot for that desktop these days, although when XP was all the rage, I usually used Azul as the desktop. I must admit that I had forgotten what a pain XP was to install, esp prior to SP1, but by the time I had obtained the full boxed set of XP and installed SP3 it was a passing fair OS. It is tedious these days, but it does let me run some favoured programs, principally "DraftChoice for Windows".Yawn.... That particular screen shot was on a desktop with Win 7.
