Having just noticed this in my running programs dialogue, I ran a Google search on it and found that it might cause some problems.
When I reported connection problems to NTL, one of the questions the technicians asked was, "Are you running a firewall?" I answered, "No." However, it seems that this may be one of the function of this patch.
Anyone else noticed connection problems since installing this patch, which is described as critical?
I had a problem with this it stopped all access to web pages, I installed firefox but this also would not show web pages. Luckily this update is listed in add remove programs and I was able to uninstall it.
This update gives problems with the following OS: win98, win98SE and win ME. The best thing is not to install it and refuse this update from Microsoft. If you use norton ghost and have a backup file from your OS, it is the best thing to reinstall this earlier version. Microsoft doesn't seem interested in this problem and some people suppose that they want to get rid of the mentioned OS above.
