I use "downdate" when I refer to update, I never liked "automatic updates". So when I do do em, I want to have total control over which ones I choose, I only choose the ones that will affect my particular system. I've never updated any of my Windows 7 machines to service pack 1, it's not that much of a service pack, compared to Vista SP1 which was necessary. This will probably screw me when they stop supporting Windows 7 with no SP's - When THAT happens, I'll finally update. I always try to keep my operating systems more or less exactly how they were when I installed it, so that I can do in-place installs.
My Windows 7 disks are all original,. with no SP, so I keep it that way mostly, only allowing a few updates that are necessary.
This also causes me problems when I have to repair my one computer with XP, because my install disk for that is SP2, but on that system I prefer SP3 so I can install Office 2010. When I need to repair that system, I have to uninstall SP3 and then reinstall it after the in place install is finished.
This system here, started out as Windows XP... I've updated it through Vista and 7 and now 8. I've got stuff running on here that I've had for years, still works great.
