How to Release the Mouse on a Virtual PC
Virtual PC is a Microsoft Windows program that allows you to create a virtual computer onto which you can load an operating system and run legacy software. If you choose to load Windows XP onto a Virtual PC partition, you may notice a feature where the Virtual PC window will not release your mouse cursor so that you can work outside of the virtual desktop window. You can free up your cursor with a simple keyboard command.
Press and hold the "ALT" key on the right side of the keyboard and tap the "ENTER" key to toggle back to window mode if you are currently in full-screen mode.
Press and hold the "ALT" key on the right side of your keyboard.
