except "optionals". But of course optional means you have the option to select or not. I generally never allow Microsoft's optional updates.
However, anything and everything else Windows Update offers you, I would recommend you accept. If you have not had any windows updates installed then there will be quite a few to be downloaded and installed and it will not all be offered in one go, but expect a never ending stream of updates for a while until your system catches up.
Lets start a new discussion about the folder problem, unless you believe this to be related to updates?
for win 7 what service packs and updates should I install?
I can;t open a new folder? what am I doing wrong? thx
