Microsoft’s next version of Window 10, currently codenamed Redstone 5, will include a new “Lean edition” designed for devices with less storage space. Sources familiar with Microsoft’s plans tell The Verge that the new edition will be offered to OEMs to load onto low-cost laptops and tablets. Windows Central first reported 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.

Twitter user Lucan discovered references to the Lean edition in the latest publicly released Windows 10 test build (17650), and at the moment the install cuts around 2GB of storage space. Microsoft is reducing the storage space needs by removing components that won’t typically be needed on these low-end devices, like Internet Explorer and other legacy desktop apps. Even regedit has been removed, and Microsoft is experimenting with removing as much as possible.

Welcome to Windows 10 Lean/CloudE/S (once again?)

This new edition started shipping with this week's Skip Ahead build (17650)

It seems to be heavily cut down, an x64 clean install is roughly 2 GB smaller than Pro

A number of existing 16GB of storage devices struggle to update to the latest Windows 10 updates. Consumers typically load on apps, media, and files that prevent Windows Update from having the necessary free space to upgrade to feature updates of the operating system. We’re expecting to hear more 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.
