What is Windows 10 Lean?
Anyone who downloaded and installed Windows 10 Redstone 5 Build 17650 for Skip Ahead may have noticed references to the previously unheard of Windows 10 Lean. Microsoft has made no announcement about this, so WTF is Windows Lean?
As you might guess from the name, this is a version of Windows 10 where the focus is on reduced size. With an install footprint around 2GB smaller than Windows 10 Pro, Windows 10 Lean is a stripped back version of the operating system with unnecessary extras cut out.
