Microsoft 7 and 8
The curtain has finally dawned on both the Windows 7 and Windows 8.1. The fat lady has sung its last song and Microsoft will no longer provide support service to its popular operating system. The company has finally fulfilled its promise on its Windows lifecycle page.

Windows 7 and 8 may be popular, but it doesn't mean it the most loved system. This is why its no big loss for Microsoft to announce the 'End of Sales' for both. 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 are Dell and Toshiba — PC manufacturers who often pre-install Windows software."

The crucial point here is OEMs were the last official way to still get copies of Windows 7 and Windows 8.1 because Microsoft already stopped retail sales to consumers about two years ago. Consequently every new Windows PC will come with Windows 10 and users will no longer have 'downgrade rights' to attain it with a previous edition.

Consequently if users still want a brand new PC with either Windows 7 or Windows 8 then move fast because all OEMs can now do is sell off their existing stock – and that won't last long. After which they will be left trawling eBay and private listings in the hope of buying a genuine copy, which would be a rarity.

Launching in 2009, Windows 7 was on sale a remarkable seven years while Windows 8/8.1 lasted just four years. A likely reflection of how differently they will be remembered.

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 flatlining Windows 10 a boost. Growth of the controversial operating system has been virtually stagnant since Microsoft's free upgrade offer ended but now – and with Christmas approaching – this should speed up its current crawl towards 25 percent market share.
