Shell
An experimental search box has been added in the upper-center area of the desktop which allow users to perform a Bing search and see the search results in Microsoft Edge. It can be toggled with the "Show search" option in the legacy desktop context menu.

This feature is only available to a subset of users, but can be enabled by running the following command with ViveTool from an elevated Command Prompt window:

Miscellaneous

 * The performance of displaying Wi-Fi networks after enabling Wi-Fi from the Wi-Fi section of Quick Settings has been improved.
 * The overall performance and reliability of the Suggested actions feature has been improved.

General

 * Fixed an issue which could cause Windows Update to stall and roll back updates for WSA users.
 * Addressed a stutter in the progress wheel animation when upgrading to a new build.

Settings
Fixed an issue that could crash the Settings app when opening and looking at the battery usage graph.

Task Manager
Addressed an issue leading to some unreadable text in the Performance page when a contrast theme was enabled.

Suggested actions

 * Suggested actions should appear for more date and time formats.
 * Addressed some issues with certain formats when copying a date and/or time.

General

 * [ADDED 5/20] We’re investigating reports that some Insiders are seeing a bugcheck with error DRIVER_IRQL_NOT_LESS_OR_EQUAL in pci.sys when attempting to upgrade to this build.
 * [ADDED 5/20] We’re investigating reports that Program Compatibility Assistant Service is using an unexpectedly large amount of CPU for some Insiders after upgrading to this build.
 * Some games that use Easy Anti-Cheat may crash or cause the device to bugcheck.

Live captions

 * Certain apps in full screen (e.g., video players) may prevent live captions from being visible.
 * Certain apps positioned near the top of the screen and closed before live captions is run may re-launch behind the live captions window positioned at top.

Safe mode

 * Quick Settings and date/time clock on the taskbar may be missing due to the  service not running.
 * Clicking Bluetooth & devices and Personalization pages may crash the Settings app due to an overrun of a stack-based buffer.
