Ok, so I finally upgraded our home PC. It was a dinosaur. 6yrs old with a staggering 1gb of RAM running XP. Heavy photo editing on Photoshop CS5 or Lightroom would bring my computer to its knees!
I'm really loving this new OS, but aside from the new layout and interface, what are the really cool tips/tricks/secrets that make Windows 7 really shine? I like the new taskbar, but what else can you do??
