I'm  pretty sure it takes ages because winrar has to check for all connected archives to the one you're opening ..  The same thing on an xp machine, trying to open a large winrar compressed archive, cpu load is pretty much stays around 1-4%, extracting uses as much cpu as possible ... so its more to do with hard drive performance, the less read/writes to the disk the faster it will be at opening the archive up.

After disabling the UAC the file gets extracted as I click it!
