Full updates vs .zip updates

My production station, a Netbook XP/SP3 station currently runs a base of 1037Rb81, overlayed with zip update to bring it to 1037S56.
My test system is a clone of the prod system, but only updated to 1037R49.

I’ve used the .zip updates because of prior issues using the ‘new’ WD on older XP Systems, I don’t know if the XP specific bug(s) were fixed.

My questions are, will the ‘full’ update’ eg 1037S65 work as a full update on XP based systems, or must I keep adding the .zip updates? And is the .zip update standalone, or does it include the prior updates available via .zip. I know I can sacrifice the test system, but I’m after a bit of advance info before I cut loose over the next couple of weeks ad do it!

Thanks,

Ken

you need to use the .zip update for XP
and updates to the main core .exe files are included in that .zip update

ah, thanks Brian.
