Microsoft has just announced the release of the Windows 10 Insider build 19640 for Windows Insiders in the Fast Ring. This is another minor update with just two minor changes related to Storage Sense and the log in experience.

You can check the full list of changes and known issues below:

General changes & improvements

  • Based on feedback, if your Downloads folder is synced to a cloud provider, we are disabling the option to have Storage Sense automatically clear out your Downloads folder on a cycle.
  • We updated our login logic, so if your PC is set up so you need to type in your username when logging in, accidentally starting your username with a space will no longer result in an error.

Known issues

  • We’re looking into an issue where some devices booting from eMMC storage bugchecked when resuming from hibernate.
  • We’re looking into reports of the update process hanging for extended periods of time when attempting to install a new build.
  • We’re working on fixing an issue for a future Insider Preview build where in Settings > Privacy, the Documents and Downloads sections show a broken icon next to their page name (just a rectangle).
  • We’re looking into reports that taskbar preview thumbnails aren’t rendering consistently (showing a blank area).

Two weeks ago, a Microsoft blog post briefly mentioned that Fast Ring Insiders should receive their first 21H1 build in June (21H1 is the next major Windows Update coming in the first half of 2021). The build 19640 isn’t that one, and we’re still waiting for the Windows Insider team to share their plans about the 20H2 and 21H1 updates.

Being in the Fast or now-deprecated Skip Ahead rings used to be exciting, but this clearly hasn’t been the case in recent months. However, the coronavirus pandemic has likely disrupted the work of many developers across the world, and Windows 10 development has likely been impacted as well. Good things come to those who wait, as the saying goes.
