Microsoft has launched another update for Windows 10, KB5039299, which is not related to security. This update focuses on resolving some problems related to the taskbar, jump lists, and more. You can get it now from the Settings app or Microsoft Update Catalogue.

This update tackles an issue that could prevent an app’s jump list on the taskbar from functioning correctly. A second problem, linked to the default Japanese Input Method Editor (IME), makes the candidate window unresponsive when it is not anticipated.

There is a solution to the problem that could happen when you right-click on certain apps. Instead of performing the task selected from their context menu, a dialog box for “Open with” appears, requiring you to specify how you would like the file opened.

This problem might impact any app that has tasks within its context menu. KB5039299 also relates to a recognized problem in Windows 10, where, among other indications, the icons on the taskbar and Start menu may cease functioning.

Here’s KB5039299’s full changelog:


  • This update 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.
  • This update addresses an issue that affects the default Japanese Input Method Editor (IME). The candidate window stops responding when you do not expect it. Then, it goes back to a former composition state at random.
  • This update addresses 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.
