ImprovementsThis non-security update includes quality improvements. Key changes include:
If you installed earlier updates, only the new updates contained in this package will be downloaded and installed on your device.
- New! Introduces WebAuthn redirection. It lets you authenticate in apps and on websites without a password when you use Remote Desktop. Then, you can use Windows Hello or security devices, such as Fast Identity Online 2.0 (FIDO2) keys.
- New! Improves storage replication that occurs over low bandwidth or congested wide area networks (WAN).
- Addresses an issue that requires you to reinstall an app if the Microsoft Store has not signed that app. This issue occurs after you upgrade to Windows 10 or a newer OS.
- Addresses an issue that stops codecs from being updated from the Microsoft Store.
- Addresses an issue that affects cached credentials for security keys and FIDO2 authentications. On hybrid domain-joined devices, the system removes these cached credentials.
- Addresses an issue that affects a network’s static IP. The issue causes the configuration of the static IP to be inconsistent. Because of this, NetworkAdapterConfiguration() fails sporadically.
- Addresses an issue that affects rendering in Desktop Window Manager (DWM). This issue might cause your device to stop responding in a virtual machine setting when you use certain video graphics drivers.
- Addresses a rare stop error that happens after you change the display mode and more than one display is in use.
- Addresses an issue that affects graphics drivers that use d3d9on12.dll.
- Addresses an issue that affects window.open in IE mode.

- Addresses an issue that forces the IE mode tabs in a session to reload.
- Introduces a Group Policy that enables and disables Microsoft HTML Application (MSHTA) files.
- Addresses an issue that occurs when the input queue overflows. This might cause an application to stop responding.
- Addresses an issue that affects the Microsoft Japanese input method editor (IME). Text reconversion fails when you use some third-party virtual desktops.

- Addresses an issue that causes WDAC to log 3091 and 3092 events in audit mode.
- Addresses an issue that affects Group Policy Objects. Because of this, the system might stop working.
- Addresses an issue that affects Windows Defender Application Control (WDAC). It stops WDAC from logging .NET Dynamic Code trust verification failures.
- Addresses an issue that occurs when a WDAC policy fails to load. The system logs that failure as an error, but the system should log the failure as a warning.
- Addresses an issue that affects non-Windows devices. It stops these devices from authenticating. This issue occurs when they connect to a Windows-based remote desktop and use a smart card to authenticate.
- Addresses an issue that might bypass MSHTML and ActiveX rules for WDAC.
- Addresses an issue that affects WDAC policies. These policies will not apply on a system when you enable SecureLaunch.
- Addresses an issue that affects the Settings app on server domain controllers (DCs). When you access System > Display, the Settings app stops working.
