Windows 10 Insider Preview Build 18970 (20H1) with media less Cloud installation released

[German]Microsoft has released Windows 10 Insider Preview Build 18970 (from development branch 20H1) for Windows Insider in Fast Ring. This build brings the reset from the cloud and an improved tablet mode.


The announcement with details about new features/changes and bugs can be found in the Windows Blog. Insiders will also be offered a cumulative update build 18970.1005 (KB4518974). Microsoft is testing its ability to maintain a build while it is released. The result for insiders should be that they are on build 18970.1005 after completing these updates. This build brings some innovations.

New Tablet PC Experience for 2-in-1 Systems

With this build, Microsoft begins introducing a new Tablet  PC user experience for 2-in-1 systems. This new user interface allows users to remain in the desktop experience without interruption when switching to Tablet mode. There are some important improvements::

  • Increased the distance between the taskbar icons
  • The search field on the taskbar is reduced to an icon
  • File Explorer switches to touch-optimized layout
  • The touch keyboard is automatically recalled when you tap text fields.

In this context, the developers have also made some small changes to the Tablet PC area in the settings. However, these changes are only rolled out to some of the insiders. The Windows Blog  describes what the affected users can expect. 

Recovery from the Cloud

This build introduces for the first time a new option to reset the system from the cloud. When users reset a system, they now have the option to download Windows from the cloud or use the local reinstall.

Until now 'Reset this PC' was only able to perform a new installation from local files and to create a new Windows installation from existing Windows files. When this feature was introduced in Windows 10 Version 1507, it had the advantage that Windows is recoverable without requiring additional hard disk space as a compressed backup copy of Windows in a hidden partition.  However, Microsoft received feedback that some users would like to use fast Internet connections to download Windows during recovery.

Important note: This is a restore operation and removes applications you have installed. In addition, if you select the "Remove all" option, the user data will also be deleted. For more information about resetting this PC and other recovery options, see

The cloud download option installs the same build, version, and edition that is currently installed on your device. This new cloud download option is available for all Windows 10 devices and is different from the Restore from Cloud feature available on some previous Windows 10 devices.

The build includes other improvements (to the Cortana rollout), but also some known issues. This is all described in the Windows Blog.
