What's new on Windows 10 21H1
As part of the new features, version 21H1 won't significantly change the way you use Windows 10. Instead, it will focus on some key areas, including quality, remote access, and security.

For example, if you use Windows Hello for biometric authentication, the new multi-camera support will help you to set another camera the default when using high-end displays that include integrated webcams.

On Windows Defender Application Guard (WDAG), this new release fixes a delay problem when opening a Microsoft Office. It improves file copying for files over 400MB in size when using the Robocopy command-line tool. And it addresses a problem that causes high usage of system memory when the WDAG container is idle.

Windows 10 21H1 also introduces better support for remote work scenarios when using Windows Management Instrumentation (WMI) Group Policy Service (GPSVC). Also, it fixes slow membership propagation when editing a user or computer group in Active Directory (AD).

Changes and improvements
In addition to the small set features, this minor update includes some under the hood tweaks, including:

New support for using the new Chromium-based Microsoft Edge as the assigned access single kiosk app.
Improves startup times for applications that have roaming settings when User Experience Virtualization (UE-V) is turned on.
Updates the Open Mobile Alliance (OMA) Device Management (DM) sync protocol by adding a check-in reason for requests from the client to the server. The check-in reason will allow the mobile device management (MDM) service to make better decisions about sync sessions. With this change, the OMA-DM service must negotiate a protocol version of 4.0 with the Windows OMA-DM client.
Turns off token binding by default in Windows Internet (WinINet).
New dfslogkey in HKEY_LOCAL_MACHINE/SOFTWARE/MICROSOFT/dfslog. The RootShareAcquireSuccessEvent field has the following possible values, including a default value of 1 to enable the log, and a value other than 1 disables the log.
Improves the ability of the WinHTTP Web Proxy Auto-Discovery Service to ignore invalid Web Proxy Auto-Discovery Protocol (WPAD) URLs that the Dynamic Host Configuration Protocol (DHCP) server returns.
Enhances data loss prevention and insider risk management solution functionalities in Microsoft 365 endpoints.

We ended the display of random paper size for a printer when it uses the Microsoft Internet Printing Protocol (IPP) Class Driver.
We enabled Windows to retrieve updated printer capabilities to ensure that users have the proper set of selectable print options.
Addresses an issue in which the WinHTTP AutoProxy service does not comply with the value set for the maximum Time To Live (TTL) on the Proxy Auto-Configuration (PAC) file. This prevents the cached file from updating dynamically.
Fixed a problem that might prevent certain CAD applications from opening if those applications rely on OpenGL.
Addresses an issue with certain COM+ callout policies that cause a deadlock in certain applications.
Fixed a problem that might cause a deadlock when a COM server delivers an event to multiple subscribers in parallel.

Fixed a problem that might prevent the correct Furigana characters from appearing in apps that automatically allow the input of Furigana characters. You might need to enter the Furigana characters manually.
