what windows version do i have installed
The Windows 10 edition you have installed, as well as the system type (64-bit or 32-bit), can all be found listed in the System applet in Control Panel. Windows 10 is the name given to Windows version 10.0 and is the latest version of Windows. If you just got a new computer, there's a 99% chance you have Windows 10 installed. (Maybe closer to 99.9%!) Windows 9 never did exist.
