What you need to know

  • A cumulative update for Windows 10 is rolling out to Windows Insiders.
  • The build doesn't include any new features but acts as a test for Microsoft's servicing pipeline.
  • The update brings Windows 10 to build 20236.1005 (KB4587587).

Microsoft rolled out yet another build of Windows 10 to Insiders, but the new build doesn't contain any new features. Instead, it acts as a test for Microsoft's servicing pipeline. The build brings Windows 10 to build 20236.1005 (KB4587587).

This isn't the first time we've seen Microsoft roll out a build without features to test things out. Testing the service pipeline is a normal practice for Microsoft leading up to the release of new updates.

Microsoft released another build to Insiders in the Dev Channel earlier this week, but that build didn't include any new features either, though it did have quite a few bug fixes.
