Windows Update informed me, regularly, until August 2010. Then, things got very confusing. I heard of the existence of Updates from ZDNet, and, finally, from Secunia. And, if over a month went by with no information, I was looking for the Updates. Since the, the updates downloaded, but failed to install, like the old days.
Only twice, I have had to rely on downloading the KB. One way or another, I figured out how to keep up to date.
So far, I don't know if any of the "fixes" from Microsoft are working. I don't want to try my luck by uninstalling any, and then trying again. I will take a look at FileHippo.
