|His updates may not be the same as yours depending on the other Microsoft software that may be installed. Either continually download and install Critical Updates, or just go for it and get Service Pack 3.|
I think it's crazy that you're reinstalling Windows every 2 months. If you really have that need, you should get Hard Disk Drive Imaging software and take a snapshot after you've installed everything the way you like. Then you can revert back to that image every 2 months without reinstalling all the Windows updates.
Or you could download the Windows XP SP3 file itself, save it to an external drive, and use it each time you reinstall your OS. That way you'll only have to download it once and you'll always have it.
I can sympathize with your Internet connection, but there are more efficient ways to go about what you had in mind. If you installed everything Chuck has, you'll probably end up installing stuff you don't even need, so try one or a combination of the 3 suggestions I made instead. If you're not sure about a specific update (or "hotfix" as Microsoft calls them), just ask. =)
