Got an email at work today telling us that
unlike other Microsoft service packs, Office XP Service Pack 2 does not include all of the fixes contained in Service Pack 1. Therefore, Service Pack 1 must be installed before Service Pack 2.
Hooray for consistency! Also, because this isn't confusing enough already, Microsoft's Office XP Service Pack 2 web page offers the following apparently contradictory statements:
This service pack also includes all updates released since Office XP Service Pack 1 (SP1).
Important Prior to installing Office XP SP2, you must install Office XP Service Pack 1 (SP1).
Well done once again, Microsoft.
(Update, 2003-01-31: more information) In other news, regarding that other Microsoft problem, Greg mentioned to me that it is possible to edit a registry other than the one the system is currently running on. If Microsoft weren't idiots, they might have mentioned this in Q271965. But then, if Microsoft weren't idiots, they wouldn't supply two programs, each of which calls itself the Registry Editor (regedit, which doesn't support some registry operations such as this, and regedt32, which is more flexible, and uses the world's ugliest tree control which doesn't respond to the same keyboard actions as every other tree control ever seen on a Windows computer).
