- Microsoft released its monthly Patch Tuesday updates for August 2021, sorting out more than 44 flaws.
- As you already know, Patch Tuesday updates enhance and add new features to the Windows OS.
- Most likely, the security improvements are the most expected part of the Patch Tuesday update list.
- Also remember that Windows 11 is almost out, and Microsoft announced the end of support for Windows 10 in 2025.
August is finally here and many users are excited to see what the next big feature update is all about.
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.
Not only will we be providing you with a detailed changelog of all the modifications brought to each major version of Windows 10, but we will also be providing you with direct download links from the Windows Update catalog.

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
The affected apps are using the ImmGetCompositionString() function.
- 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. This issue is only encountered when custom offline media or ISO images are created by slipstreaming this update into the image without having first installed the standalone servicing stack update (SSU) released March 29, 2021 or later.
NOTE
Devices that connect directly to Windows Update to receive updates are not affected. This includes devices using Windows Update for Business. Any device connecting to Windows Update should always receive the latest versions of the SSU and latest cumulative update (LCU) without any extra steps.
- 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).
NOTE
If you cannot use backup software on Windows 7 SP1 and Server 2008 R2 SP1 or later after installing this update, contact the manufacturer of your backup software for updates and support.

Windows 10 version 1909
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.
So, if you still want to receive security and quality updates, Microsoft recommends updating to the latest version of Windows 10.

This version of the OS is outdated and will no longer receive any updates from the tech company. Users that are still running this old version on their devices are strongly advised to choose a more recent one to update to.
