According to a BBC report, tech giants Microsoft have stopped sales of both Windows 7 and Windows 8 in an attempt to entice more users onto the latest version of their operating system.
Windows 7 Home Basic, Home Premium and Ultimate will all no longer be available to purchase, and neither will the unpopular newer operating system, Windows 8.
It is understood that as well as encouraging users onto the latest version of Windows 8.1 it will also help to distance the company from the failure that was Windows 8. The OS was only released two years ago, but was widely criticised for alienating desktop users.
The new interface of 8 was a drastic change from what Windows users had been used to over the years that Microsoft have been producing computing systems. With the tablet market expanding Microsoft tried to develop a system that would satisfy both the tablet and PC world, but it wasn't as successful as they'd hoped.
Many were relieved when Microsoft finally released Windows 8.1 exactly 12 months ago. The update took into account much of the feedback from 8's release, and brought back much of the familiarity that was lost in 8 like the Start button on the task bar.
Windows 7 is still by some way Microsoft's most popular operating system with 53% of their market using the five-year-old operating system, according to Net Applications. Windows 8 and 8.1 command much less of their market share with 17% in total, and Windows XP which launched 13 years ago, is still widely popular accounting for 17% of Microsoft's market.
Windows 8.1 will be succeeded by the operating system's next big update in Windows 10, which is due for release next year.
