Windows 10 (original release)

Windows 10 (codenamed Threshold, also referred to as Windows 9 or Windows TH) is the upcoming successor to the Microsoft Windows 8.1 operating system. It was believed to be Windows 9, but it was revealed to be wrong eventually, on 2014-09-30. Windows 10 intends to address some of the complaints that were made in response to the user interface in Windows 8. Screenshots of Windows 10 build 9834 were released on 2014-09-11 which show a revised Start menu interface and additional improvements to the Windows operating system.
