Windows 10 Build 19045.4651, what’s new?

Installing Windows 10 KB5040427 will upgrade your operating system to OS Build 19045.4651. This update primarily focuses on quality improvements and bug fixes. According to the release notes provided by Microsoft, KB5040427 addresses an issue that affects an app’s jump list on the taskbar.

Completing actions from that list might fail. A jump list is a menu that appears when you right-click an app on the taskbar or Start menu. It gives you quick access to recently or frequently used app items. Microsoft noted.

Microsoft is busy with the development of Windows 11, today’s update actually comes with several noticeable changes only

The Copilot app is now pinned to the taskbar and behaves like an app. This gives you the benefits of a typical app experience. For example, you can resize, move, and snap the window. For existing Windows 10 PCs, the timing of availability and delivery method will vary. This might not be available to all users because it will roll out gradually.

Fix a known issue that might occur when you right-click some apps. Instead of running the task you choose from the context menu, an “Open with” dialog appears. It asks you, “How do you want to open this file?” This issue might affect any app that has tasks on a context menu. This issue also affects the icons on the taskbar and Start menu.

  • This update addresses an issue that affects MSIX applications. When you install them from an HTTPS URI, they fail to open. This issue occurs when the download of the application is not complete. This damages the package.
  • This update affects mobile device management (MDM). When you enroll a device, the MDM client sends more details about the device. The MDM service uses those details to identify the device model and the company that made it.
  • This update addresses an issue that affects Direct Composition batched presentations. A brief flash of triangles or boxes show on the screen. This issue affects browsers, like Microsoft Edge, and other apps.
  • This update brings Country and Operator Settings Asset (COSA) profiles up to date for certain mobile operators.
  • This update addresses an issue that might stop your system from resuming from hibernate. This occurs after you turn on BitLocker.
  • This update addresses an issue that affects Windows Defender Application Control (WDAC). The issue copies unsigned WDAC policies to the Extensible Firmware Interface (EFI) disk partition. It is reserved for signed policies.
  • This update addresses an issue that affects a folder context menu. When you choose the command that removes items, the command adds items instead. This occurs when a third-party service implements a sync feature.
