I just updated my Windows an guess, what: A lot of error messages telling me drivers can’t be found or installed (mainly PeerGuardian 2 and my TV-Card) , those drivers were not (for whatever reason) certified by Microsoft, so you had to use “bcdedit -set loadoptions DDISABLE_INTEGRITY_CHECKS” to make them work, but after this “up”-date they won’t work anymore, so you will have to unistall KB932596 in your software-tab and reboot to fix this. I don’t think this update is used for anything else than to annoy people. Since the “more information” link (http://go.microsoft.com/fwlink/?LinkId=85125) currently doesn’t show anything at all (at the time of writing). this one is staying of my system until someone has figured out how to circumvent this annoyance.
By the way: You will have to exclude this update in your Windows-Update tab or it will be installed again tomorrow.
I found Microsoft’s explanation of this update, but I am not very happy with it, as it gives no details at all: http://support.microsoft.com/?kbid=932596
