Microsoft has released an optional preview update for Windows 10 version 2004 that addresses Windows Subsystem for Linux 2 issues that emerged after September’s Patch Tuesday update.
The preview update KB4577063 for Windows 10 version 2004, aka the May 2020 Update, bumps up this version to build number 19041.546.
This preview update brings many of the same fixes Microsoft released in last week’s 20H2 Beta preview for Insiders on the Release Preview Channels. Microsoft is expected to release 20H2, or the Windows 10 October 2020 Update, either this month or in November.
