I just Googled my laptop description and got back a massive list of updates available, including a program that apparently will install any updates automatically!
What has been the experience of forum members with the 'unofficial' SP4 offerings that can be found?
Myself, have only tried one of them. It was the one emanating from Greece. Sure enough, my download, found on web, did contain a Trojan. I forget the name of the particular specimen. It was, however quickly detected and disposed of by whatever AV I had running at that time, and did seem to be problem-free thereafter. I used it for a couple of years, though no-longer have that particular machine.
