Microsoft has provided a release date for Windows 10 and it's July 29th. If you are currently using Windows 7, Windows 8 or Windows 8.1 you will start seeing a new icon on your taskbar or traybar. When the new icon is clicked on it will invite you to register Windows 10 for free. If you register for the free Windows 10 upgrade, Windows will reserve your free Windows 10 upgraded and notify you when Windows 10 is downloaded so that you can chose to install it right away or pick another time to.
