Now the spy updates are not hidden, and marked as "Important." They're bound and determined to force this crap down our throats. Bastards.
"Because f*ck you, that's why." The rallying cry of the corporate world.
I uninstalled each of those KBs manually from the "Installed Updates" screen, then changed the update policy. I used to use "download and install manually" but now I'd prefer only being notified, and THEN deciding whether or not I want to download whatever is offered. I then re-ran the check for updates, and hid the offending KBs.
That was earlier this month. After reading this article, I decided to have a look and see if there was anything fishy in my update history (beyond the listed KBs that I don't want). Nothing there, at least, but my hidden updates were un-hidden (along with Silverlight and Skype, two more "do not want" things that I always hide).
