Im confused, I thought MS had a 'beta SP3' floating around, its actually a 3rd party package. Also it seems MSFN is filtering out the url for the software in question. But google is your friend "Windows XP Service Pack 3 Preview" Can this be integrated into the install source (I386)? Or stick with Ryan VMs Update Pack? And how is this different from Autopatcher? http://www.autopatcher.com/
