As it promised, Microsoft has stopped issuing updates for Windows 7 and Windows 8.1 users whose PCs run Intel's seventh-generation processors (codename Kaby Lake), AMD's seventh-generation processors (Bristol Ridge), and Qualcomm's 8996 processor or newer.
Microsoft has confirmed the move, saying: "This error occurs because new processor generations require the latest Windows version for support".
Confirmation that this previously announced policy will soon take effect came via an article recently published to Microsoft's support website.
Three major features are expected in the latest Surface tablet: Windows 10 Creators Update, Hololens support and a newly introduced Touch Bar.
According to Microsoft's support page, the error message is a result of the Windows 10 support policy. Windows 8.1 won't hit its end of life until next year, Vole is switching off its support early for new chips.
Microsoft warned users of their plans in January 2016 and again in August 2016, but this has not stopped Windows 7 fans from grousing and threatening to switch to Linux.
If you're running an older version of Windows with a newer CPU, Microsoft is about to make it very hard for you to avoid upgrading to Windows 10. Intel hinted that something similar would happen for Kaby Lake support a year ago.
If the Android community has shown anything via XDA Developers it's that compatibility shouldn't be dependent on the hardware - not even the operating system.
What's unclear is whether Microsoft had pulled the trigger on the no-patches-for-older-Windows rule and was showing users the messages outlined by the support document.
If Microsoft decides to actually opt for Ryzen 7, this will mean that Surface Pro 5 will be the most powerful hybrid device ever made. As such, the tech giant decided that only Windows 10 would run on the processors that were of the seventh generation and beyond.
The company says that over 500 million Windows 10 installs have been completed since the software was released in July 2015. At that point, some Skylake-equipped PCs would continue to receive some security updates; other such PCs would get nothing after the deadline. And the problem is exacerbated by the company's messaging via Windows Update.
