Maybe you’ve not realized yet that Microsoft’s Windows 10 is already here for more than a year. For those who are still using Windows 7/8.1, the older system is reliable enough and good to use. But if you purchase a new OEM device now, the operating system you’ll embrace is all Windows 10.
As of October 31, Microsoft has stopped selling Windows 7 or Windows 8.1 to system builders. Actually, they terminated most versions of Windows 7 two years ago, and only the professional version held on till earlier this week.
Windows 7 users are quite sticky, and according to the research report at WayBackMachine, Windows 7 64-bit became the most popular OS in 2015 by grabbing a share of 37.48%, with Windows 10 64-bit at 23.99% and Windows 8.1 64-bit at only 18.62%.
