For those on the Fast Ring of the Windows Insider program cumulative update Build, 16232.1004 is now live through Windows Update. But blink, and you'll miss it as this update is merely testing Microsoft's new "servicing pipeline."

In an updated blog post Microsoft's Dona Sarkar explains what to expect, which is not much. In fact, you may not even need a restart (our PC has the update already installed without notification). Ironically, although it does not introduce new features, it does change the binary of Notepad (they had to update something after all), and there are a few new bugs:

The primary goal of this update is to test our servicing pipeline. This update should not require you to have to reboot unless you happen to have Notepad.exe open. This update only revs the version of the OS and includes an updated binary version of Notepad.exe and nothing else. It does introduce the following issues to be aware of:

  • Make sure you've setup Mixed Reality before taking this update.
  • After installing a language pack or feature-on-demand like .NET 3.5, your PC may be offered this update again and fail.

In other words, this update is more for Microsoft than you right now, but it will hep making things better down the road for the Fall Creators Update.
