Hey Kurt, How do you come up with your magical lists of which hotfixes to slipstream, which ones to RunOnce, which ones to delete, and most importantly what order you run them in? How do you know what changes to make each month? I'm trying to achieve the same thing for manually maintaining a RIS install share of XP x86, and I've googled my bum off here, but can't find anything even close to the comprehensive work of genius that is Kurt's UpdatePrep.bat (and the RunX_W2Ksp5.bat's)! Am I missing something? Is there some MS newsletter that I should be subscribing to? -databall
