You can get MS Updates here using KB####### in Search:
You have to be careful to select the right ones for your system, and your update history can help. For Office updates they are usually cab files rather then exe's. I've not tried to master these (just clicking on them is insufficient) but once you have the KB number you can usually find them lurking on the net as exe files from MS. Sometimes you have to use Google in a cunning way to find them - bit tricky to explain on here but I always find them somewhere.
I agree, only the security ones really matter, but that is most of them. Obviously with time your security will drop but at least if you are up to date in April 2014 then you are starting from the best position.
I used Win 98 for some years after support finished - one of the "few" at that time. The problem this time is that as so many folk are sticking with XP it could become some sort of hackers paradise. Backup all your personal stuff and leave your backup device offline. That will mean if you get the crypto virus you will be able to replace the files rather than encouraging the crooks by sending money.
Always pop back and let us know the outcome - thanks
