Microsoft has made true on their earlier promise to not support the popular Windows 7 and Windows 8.1 on the latest generation of Intel and AMD processors.
According to Microsoft, "This error occurs because new processor generations require the latest Windows version for support", the document says. "Your PC uses a processor that isn't supported on this version of Windows", it said.
For example, Windows 10 will be the only supported Windows platform on Intel's upcoming "Kaby Lake" silicon, Qualcomm's upcoming "8996" silicon, and AMD's upcoming "Bristol Ridge" silicon.
Unless Microsoft sees the outrage which has erupted in some corners of the internet over this, accusing them of engaging in another underhand way to push Windows 10 upgrades - and the company thinks better of it.
The news comes as Microsoft prepares to roll out the next major update of Windows 10.
Of course, support for both Windows 7 and Windows 8.1 is going to be discontinued eventually - the former version is already in extended support, which means that it only receives security fixes.
The company's previous methods of convincing users to make the jump have upset some, and this policy is sure to ruffle feathers as well.

Harold Dutton, who voted against the bill, said it "gives police unfettered authority to stop people". Rick Perry, who called it a "government effort to micromanage the behavior of adults".
We already knew Microsoft was planning to offer official support exclusively for Windows 10 on the new Intel and AMD CPUs, but it seems the company is planning to go to great lengths to ensure these chips aren't used with older versions of the OS. While that seems simple enough to do we'd like to point out that upgrading to Windows 10 Home will cost you R2 335 or R3 999 if you'd like the Pro version.
At the time, it said it would not be releasing drivers for Ryzen running on Windows 7.
The question now becomes how many Windows 7 and Windows 8.1 users are affected.
Word of a new Microsoft support document surfaced Thursday, applying the stick to those bold enough to try and pair an older Microsoft OS with the latest silicon.
If you planned to upgrade to Kaby Lake, AMD's Ryzen, or another new processor, then you'll also finally have to move to Windows 10. Intel hinted that something similar would happen for Kaby Lake support a year ago.
But having updates blocked obviously takes the risk factor to a whole new level.
