Back in January, Microsoft made a rather surprising announcement that it was changing the support model for older operating systems running on the latest Skylake hardware. As part of the announcement, going forward, the latest processors and chipsets would only be supported on the current version of Windows. As of now, and for the foreseeable future, that means new chips will only be supported on Windows 10.

This was a surprise because both Windows 7 and Windows 8.1 are still in their ?extended support? phase, and generally that means the operating system is left as is, but security updates are done until the end of extended support. For businesses especially, many had just finished their Windows 7 upgrade and there was not necessarily a big push to start over again. But at the same time, workstations need to be replaced. As a slight reprieve, Microsoft said in January that they would provide a list of computers that would have support for Skylake until July 2017. Since then, the list has been made available here: http://windows.microsoft.com/en-us/windows/skylake-support

There was some ambiguity about the initial notification though. After July 2017, patches that are found to cause an issue with Skylake systems would be excluded from certain security patches. But what that meant exactly wasn't stated. Today Microsoft has both extended the diary date for the end of support, as well as provided a bit more clarity on what will happen after.
