Microsoft has yet another Cumulative Update available to Insiders on the Dev Channel. The update doesn't include any new features or fixes. Instead, its purpose is to test Microsoft's servicing pipeline. The build brings Windows 10 to build 20241.1005 (KB4589464).

This type of testing is commonplace for Microsoft when leading up to a release of new updates. With the Windows 10 October 2020 Update rolling out, it's important for Microsoft to have all of its servicing pipelines in tip-top shape.

While this Cumulative Update doesn't include any new features or fixes, it builds off of a recent build that does. Windows 10 Build 20241 started rolling out to Insiders on Wednesday. That build includes theme-aware splash screens for UWP apps. Many of Microsoft's own apps already have theme-aware splash screens to support the feature.

The Windows blog includes the build notes for this latest Cumulative Update and for the most recent Insider Build that includes new features.
