This month’s Tuesday Patch marks the end of support for Windows 10 version 21H1, also known as the May 2021 Update. All versions will no longer receive cumulative updates with bug fixes, security patches and other enhancements.

Microsoft released Windows 10 21H1 in May 2021. This was a minor feature update with only two notable changes: multi-camera support for Windows Hello and improved performance of Windows Defender Application Guard (WDAG) and Windows Management Instrumentation (WMI) Group Policy Service (GPSVC). Since Microsoft was busy preparing Windows 11 for public release, there were no new features for regular consumers.

Like all Windows versions released in the first half of the year, Windows 10 21H1 only received 18 months of support. The successor to the 21H1 version, 21H2, will be supported until 13 June 2023.

Windows 10 21H1 isn’t the only version of Windows heading west. Microsoft will soon stop issuing advanced security updates for Windows 7 and disable Windows 8.1. The company plans to end support for these two older versions of Windows in January 2023.

Those still using Windows 10 21H1 should upgrade to a newer version of Windows 10 or upgrade to Windows 11, which already has many new features and improvements. If you’re not ready to embrace Microsoft’s latest operating systems with their controversial changes, Windows 10 21H2 and 22H2 (with “limited” productivity features) are here to save the day. They don’t introduce new features or change hardware requirements, and they only take a few minutes to upgrade.
