Windows 10 May 2020 Update

Windows 10 20H1 is a version of Windows 10 expected to ship around April 2020. This version is notable for having the first insider preview builds released before Windows 10 19H2, which it is supposed to replace.

The first Insider Preview Skip Ahead build for 20H1, build 18836, released on 2019-02-14, although earlier builds (beginning after the forking of 19H1 to rs_release) were sighted on MSFTBuffet a few weeks earlier.
