May. 29, 2020 / Updated by Bessie Shaw to News

Los Angeles, Calif. - August 29th, 2019 - August is coming to an end. To catch the end of August, Microsoft introduces a new 20H1 (also known as Windows 10 May 2020 Update version 2004) preview build to Insiders in the Fast ring today, along with a Cumulative Update Build 18970.1005 (KB4518974). That's Windows 10 Insider Preview Build 18970 (20H1). The company is just testing their ability to service a build at the same time it is released. Let's check out the changelog for more details.


What's new in Windows 10 Insider Preview Build 18970 (20H1)

Build 18970 comes with a couple of new features of note, including a new tablet experience for 2-in-1 convertible PCs. These are all the important updates.

A new tablet experience for 2-in-1 convertible PCs


With Build 18970, a new tablet experience for 2-in-1 convertible PCs is currently available for a portion of Insiders as a Beta. This new experience allows users entering tablet posture to stay in the familiar desktop experience without interruption, plus a few key touch improvements:

  • Increased spacing between Taskbar icons.

  • Search box on taskbar collapsed into an icon.

  • File Explorer switches to touch optimized layout.

  • Touch keyboard auto invokes when you tap text fields.

As part of this, there are also a few small changes in the tablet section in Settings.

If this new experience is available on your PC, you can test it through these steps:

Step 1. Use your convertible PC as a laptop as you normally would–opening apps and interacting with them.

Step 2. When you’re ready to pick it up and go or simply lean back on the couch, you can fold back the keyboard or remove it altogether, and it should switch to this new mode shown above.

Step 3. Now use your device as a tablet with touch.

A new Reset this PC option – Cloud Download


Reset this PC now provides users a new choice to download Windows or use local reinstall. That’s cloud download. The cloud download option will reinstall the same build, version, and edition, that is currently installed on your device. This new option is available to all Windows 10 devices and is different from the “Recover from the cloud” feature available on some earlier Windows 10 devices.

Note: This is a recovery operation and will remove apps you have installed. Additionally, if the “Remove everything” option is selected, your data will also be deleted.

Here is a known issue with this new option:

The cloud download option is not currently working when specific optional features are installed. The process will begin, but an error will occur and roll back the changes.

To work around this issue, remove the optional features before trying this option. The optional features are: EMS and SAC Toolset for Windows 10, IrDA infrared, Print Management Console, RAS Connection Manager Administration Kit (CMAK), RIP Listener, all RSAT tools, Simple Network Management Protocol (SNMP), Windows Fax and Scan, Windows Storage Management, Wireless Display, WMI SNMP Provider.

Continuing the Cortana rollout

With Build 18970, Microsoft is continuing the rollout of the new Cortana experience. Now it’s available to all Insiders in the Fast ring in the United States.
