In February last year, Microsoft said that it would give a one year warning of when systems with Windows 7 preinstalled would no longer be available from OEMs. That time has finally come to pass. As spotted by Ed Bott, there’s now a date after which Windows 7 OEM preinstalls will no longer be available: October 31, 2016.
That same date will also apply to Windows 8.1. Windows 8 preinstalls will end a few months earlier than that, June 30, 2016. This means that after October 31 next year, the only version of Windows that will be available on a new system from a PC builder will be Windows 10. Right now, OEMs can still offer Windows 7 Professional (though not any of the other versions), Windows 8, Windows 8.1, and Windows 10.
Windows 7 will remain supported until January 10, 2020. It left mainstream support earlier this year, so it’s no longer eligible to receive non-security fixes or extra features but still has many years of security updates.
