The guide doesn't mention it (maybe for a reason), but if you use the systeminfo command from a command line, it lists the hotfixes that have been applied to your installation. What I don't understand about the systeminfo output is that the first 38 hotfixes all say "File 1". Can anyone explain this or point me to an explanation? [My search of "File 1" did not turn up any results.] If it matters, my OEM XP disk includes SP2.
