Microsoft recently announced that all next-gen CPUs built by Intel , AMD, and Qualcomm will only support Windows 10 instead of older versions of Windows.
These CPUs include Intel’s Kaby Lake, AMD’s Bristol Ridge, and Qualcomm’s Snapdragon 820 processors.
Microsoft also plans to remove Windows 7 and Windows 8.1 support for Intel’s new Skylake processors, but will still support “a list of specific new Skylake devices” until July 17, 2017. This doesn’t mean that Microsoft will drop support for older CPUs — support for Windows 7 on older chips will last through Jan. 2020, and support for Windows 8 won’t cease until Jan. 2023.
Why is Microsoft doing this?
Consumers hoping to install an older version of Windows on their new PCs will likely be disappointed by Microsoft’s announcement. But Microsoft’s decision makes sense. According to Net Market Share, nearly 90% of PCs worldwide run Windows, but only 10% run Windows 10. Fifty-six percent still run Windows 7, 13% run Windows 8/8.1, while 11% run Windows XP.
This fragmentation limits Microsoft’s ability to unify its ecosystem with new features like Cortana and universal apps. It also forces the company to waste time and resources on supporting older operating systems with security updates. Microsoft only stopped supporting Windows XP in April 2014, nearly 13 years after its initial release. To get more of these users on the same page, Microsoft offered Windows 10 as a free upgrade for most Windows 7 and Windows 8.1 devices.
