Maybe what we need to do is RESTRICT it's privileges? So far I've tried setting the Boot Camp Control Panel process to run in both compatibility mode AND with administrator privileges. Maybe what we need to do is RESTRICT it's privileges? I suspect that it detects it has administrator privileges and try to access something it shouldnt. After I restarted, Boot Camp Control Panel worked flawlessly on my secondary Windows 8 user account. On a related note, as soon as I set up the second account, it took a very long time to initialize (I stared a 'your PC is being prepared' screen for about 5 minutes), and as soon as it finished, I noticed a 'bootcamp service installed - you must restart your computer' message. Unfortunately, the settings made there are account-specific, so the primary account remains unable to use the function keys or enhanced trackpad features. Strangely enough, the Boot Camp Control Panel works PERFECTLY for my second, non-admin Windows 8 account.

I have this exact problem - but ONLY with my primary Windows 8 admin account. I have a brand new MacBook Pro Retina, and went ahead and installed the Windows 8 Release Preview (RP) in Boot Camp.
