Microsoft has announced that it is ending the life of Windows 7 and Windows 8. Microsoft is announcing the ‘end of sales’ for two important Windows versions in the history of the software giant. With Windows 7, Microsoft regained lost trust with Windows Vista but failed to persuade users to upgrade to “touch-friendly” Windows 8.

Microsoft explains the move: “End of sale refers to a date when a specific version of Windows is no longer shipped to retailers or original equipment manufacturers (OEMs). Examples of OEMS are Dell and Toshiba-PC manufacturers who often use Windows.” The move basically means PCs won’t be shipped with Windows 7 and Windows 8.1 pre-installed, and Microsoft has already stopped selling both versions through retail packaging.

The move will help Microsoft take Windows 10 further in the ever-competitive PC market. PC sales have been declining for almost eight consecutive quarters, and with the increasing penetration of mobile devices, PC sales are unlikely to be positive anytime soon. Microsoft currently has more than 400 devices running Windows 10, and with more PC shipping outside of Windows 10, the count will help Microsoft reach its ultimate goal of 1 billion Windows 10 devices.

After the defeat of Windows 7 Vista came as a saving grace for Microsoft. Microsoft has seen enterprises easily upgrade from XP to Windows 7, and Windows 7 itself has been available for sale for almost seven years. Windows 8 and Windows 8.1 stay on the shelves for only four years, which proves the results of the OS.

However, for those who are already running Windows 7 and Windows 8.1 on their PC, don’t worry. Microsoft plans to continue supporting Windows 7 and Windows 8.1 until January 2020 and 2023, respectively. Windows 10 upgrades have stalled since the free update ended in July, and this special move will help the new OS reach more potential customers.
