Programs and features details missing.

I'm not sure what triggers the updates to make the optical drive go away. I just get calls to fix it when it happens. I think that some updates were major and amounted to an uninstall and re-install... but again, I'm not positive because I don't use iTunes.

Yes, I going to keep iTunes installed on my second hard drive, and prevent it from loading on start-up after every update. That seems to be the most functional setting so far.
