Microsoft has released Windows 10 Build 19045.4593 to Windows Insiders in the Beta and Release Preview Channels. Upgrades to Windows Backup and the taskbar search are now available to Windows Insiders using Windows 10 in the Beta Channel.

The update addresses issues with MSIX applications, mobile device management, default Japanese Input Method Editor (IME), Direct Composition batched presentations, Country and Operator Settings Asset (COSA) profiles, system resuming from hibernate, Windows Defender Application Control (WDAC), app jump lists on the taskbar, and folder context menus. It also aims to improve stability in app searching and allows for seamless backup and restoration of personalization preferences, such as Activity History and Printer Device Settings. To be the first to receive features, users can turn on the Windows Update toggle.



Releasing Windows 10 Build 19045.4593 to Beta and Release Preview Channels

Hello Windows Insiders, today we are releasing Windows 10 22H2 Build 19045.4593 (KB5039299) to BOTH the Beta Channel and Release Preview Channel for Insiders who are on Windows 10, version 22H2.

For Windows Insiders on Windows 10 in the Beta Channel, we’re beginning to roll out the following improvements:

[Search on the Taskbar]

  • We’re made some fixes to improve the overall stability of searching for apps in the search box on the taskbar.

[Windows Backup]

  • You will be able to seamlessly backup and restore personalization preferences of Activity History and Printer Device Settings that are not hardware or accessory dependent such as “Let Windows manager my default printer” and “Store my activity history on this device”. The goal is to ensure that the most used preferences of these settings are backed up, while avoiding those that are tied to specific hardware, to facilitate a seamless transition to a new PC.
  • We are making some important bug fixes to enhance the backup and restore functionality. As part of this work, the issue causing backup failures when desktop and lock screen backgrounds were backed up twice has been resolved.

Insiders in the Beta Channel on Windows 10 who want to be the first to get features gradually rolled out to you can  turn ON the toggle to get the latest updates as they are available via Settings > Updated & Security > Windows Update. Over time, we will increase the rollouts of features to everyone with the toggle turned on. Should you keep this toggle off, new features will gradually be rolled out to your device over time once they are ready.

This update includes the following features and improvements for Windows Insiders in BOTH the Beta and Release Preview Channels:

  • 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 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 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 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 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.
