Windows 10 (21H1) Build Tracker

This ITPro Today Build Tracker follows the public development cycle of the Windows 10 (21H1) feature update for Windows 10 in the Dev Channel. It is expected to be generally available sometime in the first half of 2021.

The IT Pro Guide to Microsoft Insider Programs

Microsoft develops future updates for Windows 10 across three development channels (Dev, Beta, and Release Preview Channel). 

This build tracker will provide enterprise and business customers a chronological reference list of all pre-release builds available in the Dev Channel for Windows 10 (21H1).

According to Microsoft, the key considerations for Dev Channel builds are:

  • Targets highly technical users who can deal with bugs and disruptions to their workflow.
  • Provides advanced access to the earliest builds in the development cycle for testing the latest features, enhancements, and compatibility.
  • Expect some rough edges and instability during testing. These builds should not be installed on production devices.
