Of course, today is also the day the monthly Patch Tuesday updates hit live, and as always, they bring a host of new features, improvements, and fixes for the most common Microsoft bugs found over the last month.
Since each cumulative update is different for each version of Windows 10, it would be wrong to talk about a singular changelog, and that is why this article exists.

Windows 10 versions 21H1, 20H2, and 2004
Windows 10 v21H1 is the latest major version of Windows 10, and as such has the most experimental features on it.
Fortunately, most bugs that were first present when it was first made available have been weeded out, and this version of Windows 10 is far more stable.
Cumulative update name
Improvements and Fixes
- This build includes all the improvements from Windows 10, version 2004.
- No additional issues were documented for this release.
Known issues
- When using the Microsoft Japanese Input Method Editor (IME) to enter Kanji characters in an app that automatically allows the input of Furigana characters, you might not get the correct Furigana characters. You might need to enter the Furigana characters manually.
NOTE
- Devices with Windows installations created from custom offline media or custom ISO image might have Microsoft Edge Legacy removed by this update, but not automatically replaced by the new Microsoft Edge.

NOTE
- After installing the June 21, 2021 (KB5003690) update, some devices cannot install new updates, such as the July 6, 2021 (KB5004945) or later updates. You will receive the error message, “PSFX_E_MATCHING_BINARY_MISSING”.
- After installing this update, the Elastic File System (EFS) API OpenEncryptedFileRaw(A/W), often used in backup software, will not work when you back up to or from a Windows Server 2008 SP2 device. OpenEncryptedFileRaw will continue to work on all other versions of Windows (local and remote).

As the Redmond-based tech company said not long ago, Windows 10, version 1909 reached the end of service on May 11, 2021, for devices running the Home, Pro, Pro for Workstation, Nano Container, and Server SAC editions.
Devices still running this version of the OS will no longer receive monthly security and quality updates that contain protection from the latest security threats.
