None of my computers received this patch automatically yesterday. I was unwilling to wait, since so much doesn't work without ActiveX. I went ahead and got the patch yesterday evening using Microsoft Update.
I learned a lot about how many programs use ActiveX for one kind of Web access or another theses past few weeks. I wish we could all do without ActiveX but life without it is miserable in Windows. Trying to figure out what needs to go into the Trusted Zone if ActiveX is turned off in the Internet Zone is no small task. I never could get the Microsoft http://safety.live.com site to work even though I made everything that came up blocked there as "trusted".
