I install WMP11 by extracting it's installation .exe file and running only wmfdist11.exe and wmp11.exe (to avoid that annoying validation) and it works just fine. Is it possible to integrate it into Win XP installation just by adding these two .exe files, not using WMP11 Slipstreamer? And what about Tweak UI Powertoy? Could I just add it's installation .exe file or is there more to it?
