Windows 7: What is Trustedinstaller.exe?

What is Trustedinstaller.exe?

Sometimes I see exessive hard disk activity, and when i check Task Manager I find a process called TrustedInstaller.exe. I've heard it has something to do with Windows Update, but it's not installing or downloading any updates (I check this in Control Panel). It probably just is some new crap that Windows 7 has, but does anyone have any explanations to what it does and why it's there? And has anyone else ssen this in Task Manager?

Thank you!

I have the same problem. How so I stop TrustedInstaller from hogging about 25% of my CPU? (Windows 7 x64)
And how can I tell if it has been taken over by a virus?
