Microsoft will continue to provide security updates for Windows 7 to business customers that pay for support, according to ZDNet, but not individual users.

Windows 7 was released in 2009 and is still one of the most widely used desktop operating systems. Windows 10 finally overtook Windows 7 in the desktop market at the end of last year, according to ZDNet. NetMarketShare's December 2018 report showed that 39.2 percent of the machines they collect data from used Windows 10, while 36.9 percent used Windows 7, according to ZDNet.
