After clicking away for a couple of years the window that kept popping up telling me there were updates available for Windows (we have ME), having read in the wake of all the recent virus/worm scare stuff that downloading the upgrades can really help virus/worm prevention I went ahead and "signed up" for upgrades (is that how it works?) the next time the window appeared. Now I've been reading that downloading the upgrades is not a good thing. How does one "unsubscribe" to them? Thx.
