UDPATE 5/21: Windows 10 Insider Preview Dev Build 21387.1 (co_release) - May 21

UPDATE 5/18: We are starting to roll out Cumulative Update Build 21382.1000 (KB5003837). This update does not include anything new and is designed to test our servicing pipeline.

NOTE: Some Insiders with the Arabic, Greek, Dutch, Polish, Portuguese (Brazil), Portuguese (Portugal), Romanian, and Russian languages installed may see KB5003837 fail with error 0x80070002 the first time trying to install the update. It should succeed on subsequent attempts.

This update DOES NOT include any fixes for the known issues listed below.

Hello Windows Insiders, today we are releasing Windows 10 Insider Preview Build 21382 to Windows Insiders in the Dev Channel.

What’s new in Build 21382

Bringing HDR support to color managed apps

HDR mode changes the behavior of some creative and artistic apps that use International Color Consortium (ICC) display color profiles, such as Adobe Photoshop, Adobe Lightroom Classic, and CorelDraw (amongst others). In the past, these apps were limited to targeting the sRGB color gamut.

We have added a new feature that lets these apps get accurate color and access the full gamut of your HDR display. To turn this feature on, close your application, right-click the app’s icon and click in Properties > Compatibility tab and then under Settings select “Use legacy display ICC color management”. This flag only has an effect in HDR mode.

Changes and Improvements

• As some Insiders have noticed, Device Manager now has the ability to view drivers alongside of devices. The new driver focused “Devices by drivers”, “Drivers by type”, and “Drivers by devices” views enable users to view, install, and remove drivers, while the new “Add drivers” action enables users to add and install new drivers across all applicable devices. Managing drivers directly is more intuitive in many situations than working with them by way of the devices they are installed on, so we hope that developers and power users alike will enjoy the added flexibility. This change was added in Build 21343. See: How to Change Device Manager View Mode in Windows 10
