Announcing Windows 10 Insider Preview Build 20215
Hello Windows Insiders, today we’re releasing Windows 10 Insider Preview Build 20215 to Windows Insiders in the Dev Channel.
Other updates for Insiders
Windows 10 search now supports dark theme
For Insiders who have their system theme set to dark, we are introducing dark theme search results for the Windows 10 search experience on the taskbar. This server-side change is rolling out to all Windows Insiders in the Dev Channel. This change will make the transition between Start and search results easier on the eyes now that both support dark theme. Let us know what you think!
Updates for developers
The Windows SDK is now flighting continuously with the Dev Channel. Whenever a new OS build is flighted to the Dev Channel, the corresponding SDK will also be flighted. You can always install the latest Insider SDK from aka.ms/InsiderSDK. SDK flights will be archived in Flight Hub along with OS flights.
