Of course, today is also the day the monthly Patch Tuesday updates go 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.

Improvements and fixes

Addresses an issue that prevents some applications, such as Microsoft Office and Adobe Reader, from opening or causes them to stop responding. This occurs on devices that are subject to Microsoft Exploit Protectionfor Export Address Filtering (EAF).

Known issues

Windows 10, version 2004

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.

To avoid this issue, be sure to first slipstream the SSU released March 29, 2021 or later into the custom offline media or ISO image before slipstreaming the LCU. To do this with the combined SSU and LCU packages now used for Windows 10, version 20H2 and Windows 10, version 2004, you will need to extract the SSU from the combined package. Use the following steps to extract the using SSU.

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. SPONSORED 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.

Windows 10 version 1809
