Windows 11 build 21327 is a build of Windows 11, which was mentioned in a post on the Visual Studio Feedback site on 11 March 2021.[1] As the build tag is repeated multiple times throughout the thread, it is unlikely that it is a typo of 21327.1000.rs_prerelease.210226-1427.

This build is one out of many known builds to be compiled from a branch with the fs prefix. The prefix stands for Firesteel, the codename for an internal Microsoft self-hosting effort related to Windows 11 development.[2]
