• This update addresses an issue that affects the audio for a Bluetooth device. When you connect it, the volume is set to maximum.

• This update addresses an issue that might stop games that have BattlEye anti-cheat from working. This issue applies to Arm64 devices.

• We are advancing the Copilot experience on Windows. It is now pinned to the taskbar and will behave like an app. This gives you the benefits of a typical app experience. For example, you can do things like resize, move, and snap the window.

• This update affects the Windows Management Instrumentation Command line (WMIC). The default state of Feature on Demand (FoD) for new installations is “Disabled.” If you upgrade to Windows 11, version 24H2, the default state of FoD is “Enabled.”

• Starting in this update, File Explorer adds the Mark of the Web (MoTW) tag to files and folders that come from untrusted locations. When MapUrlToZone classifies a file as “Internet,” that file also gets this tag. Because of this change, the “LastWriteTime” time stamp is updated. This might affect some scenarios that rely on file copy operations.
