Updated Adobe Reader, now I boot slowly

[Strygun]

So last night, I opened a pdf file and adobe reader told me I had two updates to install. I had nothing better to do, so I installed them. Now, ever since, my computer boots differently. It'll boot about halfway... meaning about half of my startup items will boot up, but then it sort of hangs. Nothing really happens for about 30 seconds and then everything else boots up just fine.

What's up here? I've opened taskmanager during boot up and everything looks fine, there's nothing hanging or taking up massive amounts of resources (that I can see.) I checked the registry and saw what was starting up. Adobe Reader was there, so I unchecked that, but that didn't seem to solve the problem.

Any ideas? What can I do to see what's going on?
