Windows 10 Build 18362.10019 (19H2, Slow Ring)

Microsoft is releasing Windows 10 build 18362.10019 to Insiders running the OS version 1903 'May 2019 Update' who have configured their devices to receive the updates from the Slow Ring. The patch replaces two previously released updates, 18362.10014 and 18362.10015.

Unlike the previous updates, Build 18362.10019 comes with all new features turned on by default. See Controlled Feature Roll-outs.

The change log for Build 18362.10019 includes the following fixes and changes.

What's new in Windows 10 Build 18362.10019

• Windows containers require matched host and container version. This restricts customers and limits Windows containers from supporting mixed-version container pod scenarios This update includes 5 fixes to address this and allow the host to run down-level containers on up-level for process (Argon) isolation.
• A fix to allow OEMs to reduce the inking latency based on the hardware capabilities of their devices rather than being stuck with latency selected on typical hardware configuration by the OS.
• Key-rolling or Key-rotation feature enables secure rolling of Recovery passwords on MDM managed AAD devices upon on demand request from Microsoft Intune/MDM tools or upon every time recovery password is used to unlock the BitLocker protected drive. This feature will help prevent accidental recovery password disclosure as part of manual BitLocker drive unlock by users.
• A change to enable third-party digital assistants to voice activate above the Lock screen.
• You can now quickly create an event straight from the Calendar flyout on the Taskbar. Just click on the date and time at the lower right corner of the Taskbar to open the Calendar flyout and pick your desired date and start typing in the text box – you’ll now see inline options to set a time and location.
  
• The navigation pane on the Start menu now expands when you hover over it with your mouse to better inform where clicking goes.
• We have added friendly images to show what is meant by “banner” and “Action Center” when adjusting the notifications on apps in order to make these settings more approachable and understandable.
  
• Notifications settings under Settings > System > Notifications will now default to sorting notification senders by most recently shown notification, rather than sender name. This makes it easier to find and configure frequent and recent senders. We have also added a setting to turn off playing sound when notifications appear.
• We now show the options to configure and turn off notifications from an app/website right on the notification, both as a banner and in Action Center.
• We have added a “Manage notifications” button to the top of Action Center that launches the main “Notifications & actions” Settings page.
• We have added additional debugging capabilities for newer Intel processors. This is only relevant for hardware manufacturers.
• We have made general battery life and power efficiency improvements for PCs with certain processors.
• A CPU may have multiple “favored” cores (logical processors of the highest available scheduling class). To provide better performance and reliability, we have implemented a rotation policy that distributes work more fairly among these favored cores.
• We have enabled Windows Defender Credential Guard for ARM64 devices for additional protection against credential theft for enterprises deploying ARM64 devices in their organizations.
• We have enabled the ability for enterprises to supplement the Windows 10 in S Mode policy to allow traditional Win32 (desktop) apps from Microsoft Intune.
• We have updated search in File Explorer to show web-powered suggestions in addition to files locally indexed on the PC.
• We have added the ability for Narrator and other assistive technologies to read and learn where the FN key is located on keyboards and what state it is in (locked versus unlocked).

In addition to the 19H2 features being turned on for everyone in the Slow ring, this update also includes the general improvements for these features.
