If you're using Windows 10, you're about to experience a significant increase in efficiency.

Microsoft releases security and quality updates for Windows every month, resulting in a substantial amount of content that can quickly consume the network bandwidth of users operating on slower networks. To reduce the demands on your network, Microsoft is now taking a page from the Windows 11 playbook and reducing the size of Windows 10 update packages.

Windows 10 is becoming more like Windows 11

Windows 11 cumulative updates are more efficient than update packages for Windows 10. This is achieved through efficient packaging, including the removal of reverse differentials from the cumulative update package. To understand how the update size for Windows 11 is reduced, refer to How Microsoft reduced Windows 11 update size by 40%.

Microsoft is bringing the same functionality to Windows 10, version 22H2, thereby decreasing the size of the monthly Latest Cumulative Update (LCU) package. This feature will be available starting with the April 23, 2024 (KB5036979) monthly release, which helps you and your organization to conserve network bandwidth.

Simply approve and apply the update as you would do today. Devices on Windows, version 10 22H2 will observe a dip in size from 830 MB in the April 9, 2024 (KB5036892) release to approximately 650 MB in the April 23, 2024 (KB5036979) release.

Make sure you're ready

This reduction of the LCU package size offers advantages such as reduced bandwidth usage, faster downloads, minimized network traffic, and improved performance on slow connections. If you maintain Windows 10, version 22H2 for deployment to new devices, make sure you're ready for these improvements by taking the following steps:

  1. Check to see if you have serviced your image since the July 23, 2024 update (KB5028244).
  2. If you have not, apply standalone SSU KB5031539.
  3. After this, apply an April 23 or later quality update.
