Windows 7 and 8 are now not for sale anymore. Microsoft has said that these operating systems can no longer be bought with a new PC. A recent report said, End of sales refers to the date when a particular version of Windows is no longer shipped to retailers or Original Equipment Manufacturers, OEMs.
Examples of OEMs include Dell and Toshiba, PC manufacturers who often pre-install Windows software.

Reports say that despite ongoing updates support for Windows 7 and Windows 8.1 until January 2020 and 2023, the end of sales is likely to give the flat lining Windows 10 a boost. Microsoft announced that it would roll out two major updates for Windows 10 next year. The reports say that while the first major update for 2017 - codenamed Redstone 2 - would release in the early part of 2017, the second one - codenamed Redstone 3 - might be released in 2017 summer.
