Microsoft is working on a new edition of Windows 10 that Microsoft internally calls ‘Windows 10 Lean’, currently codenamed Redstone 5. It was spotted in the ISO for the latest Windows 10 Insider Preview, build 17650. that the edition will be available for devices with 16GB of storage, and it’s primarily designed to ensure these machines still receive Windows updates. first reported
According to Lucan on Twitter, the OS is slimmed down, with an installation size that's about 2GB smaller than Windows 10 Pro. Microsoft is reducing the storage space needs, by eliminating components that won’t typically be needed on these low-end devices, like Internet Explorer and other legacy desktop apps.
This is more likely to be a slimmed down version of Windows 10 that's made for devices with low storage. Microsoft still lists 16GB as the minimum amount of storage for a 32-bit installation of Windows 10, and 20GB as the minimum for 64-bit. There are still plenty of devices that ship with 32GB, and that still leaves very little room for actual use after Windows is installed.
We’re expecting Microsoft to throw more lights about the Windows 10 Lean edition and Microsoft’s plans for the future of Windows 10 at the company’s Build developer conference in early May.
