I was looking though my startup program list and I noticed I have 3 instances of "Microsoft Windows host process (Rundll32)" on that list. I don't know when that happened, but I don't think that there are supposed to be three of them starting at the same time. Taskmgr shows three running as well.

My question, what does that process do, and if I disable 2 of them, will that adversely affect my computer?

Thanks.

I use a program called infobar.

It's very important that you take care of rundll32 issues. Although it could be a glitch with Vista, there's always the possibility of malware, e.g. a keylogger from hackers trying to get access to your system. Verify a program recently installed, especially if it was downloaded or it's a peer-to-peer application. Again, it might not be anything serious, but you shouldn't take chances.

Thanks, Disabled all three, and computer is running fine with less process.

A good prog to use would also be Vista Tweak Manager. Its SW.

Rundll32 is needed to run some applications, so disabling it might be a bad idea. You may want to check this link: http://windowsxp.mvps.org/rundll32.htm
