Releasing Windows 10 Build 19045.4593 to Beta and Release Preview Channels

Going forward, the Beta Channel and Release Preview Channel will receive the same Windows 10 builds; however, the Beta Channel is where new features will be tiried out with Insiders that are not yet ready for all Windows 10 customers.

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.

ADDED 6/19:

*New! 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. PLEASE NOTE: Managed commercial devices will not receive this new experience. This includes devices not running Windows 10 Home and are managed by an IT administrator.

March 2025 Microsoft Photos update now rolling out to Windows Insiders

Today we are beginning to roll out a Microsoft Photos app update to Windows Insiders on Windows 11 across all Insider Channels and also to Windows Insiders on Windows 10 in the Release Preview Channel. Not all Insiders will see this update right away or the features noted below as we roll things out to more Insiders over time. Here are some highlights of what is new and improved in this update!

Search the web with OCR-extracted text

The Photos app now comes with a powerful Optical Character Recognition (OCR) feature which supports over 160 languages, which began rolling out again for Windows Insiders on Windows 11 and Windows 10 at the end of January. To use OCR, simply click the Scan Text button in the Photos Viewer. The app will highlight the recognized text with an overlay, allowing you to easily select and copy it to your clipboard. With this update, we're adding "Search in Web" functionality so you can quickly search for any selected text from your images right from the app.

This enhancement makes it easier than ever to extract and find online results of text from documents, notes, screenshots, and more. Whether you're capturing text from a document or simply exploring the contents of an image, the Photos app's OCR and online search features streamline your workflow and boost your productivity.

Quick access to AI editing and visual search from File Explorer and your desktop

Introducing new File Explorer shortcuts that give you direct access to AI editing and Visual Search without needing to open the Photos app.

Right-click an image in File Explorer and select "Create with Designer" to add rich text, adjust composition with object selection, or enhance colors with color pop.

Plus, use the "Erase Object" shortcut to quickly remove unwanted elements. And with "Visual Search with Bing" shortcut, you can easily look up similar images, related products, and more right from your desktop.

Show subfolder images and videos in the Photos Gallery
Now you can use filters to adjust how your subfolder and gallery content show up. By enabling "Show subfolders", you can now see all the images and videos from subfolders in the Gallery, making it a richer navigation experience.

Introducing the new Copilot button in the Photos app
We are excited to unveil the Copilot button in the Photos app that brings AI directly to your fingertips.

This Copilot integration is rolling out soon and with this new feature, you can effortlessly share your photos with AI to receive:

• Photo Editing Tips: Get expert advice on enhancing your images.
• Image Insights: Discover interesting details about your photos.
• Framing Suggestions: Improve your photography skills with personalized recommendations.

New Copilot button at the top of Photos Viewer highlighted in a red box.

Other fixes and improvements

• Due to popular requests, the Photos app now supports JXL files.
• We implemented bug fixes for the Image Creator and Restyle Image features on Copilot+ PCs to improve overall quality and performance. This includes successfully loading Image Creator in the Photos app on the initial launch of Photos and being able to Save generated images under a different file name.

To get these new features, update your app to version 2025.11030.20006.0 or higher via the Microsoft Store. This update is currently rolling out, so it may not be available right away. As always, we love getting your feedback so please share your thoughts in Feedback Hub (Win + F) under Apps > Photos.
