- Microsoft pushes build 19045.4593 for Windows 10 22H2 in the Beta and Release Preview Channels.
- The update brings improvements for Windows Backup and Search.
- The preview update KB5039299 also ships various non-security fixes.
Microsoft has made available the preview update KB5039299 (build 19045.4593) for Windows 10 22H2 in the Beta and Release Preview Channel of the Windows Insider Insider Program. This is a small update that changes some existing features and fixes several issues.
According to the official changes, Windows 10 build 19045.4593 improves the Search experience when searching for apps from the search box in the Taskbar.
In addition, this release changes the Windows Backup functionality to include your activity history and printer settings, but only the preferences available on Windows, not settings from the printer manufacturer.
Furthermore, Microsoft is rolling out fixes that should improve the process of backing up and restoring data using the Windows Backup feature.
These changes are only available in the Beta Channel, while the following fixes are rolling out for devices in the Release Preview and Beta Channel.
According to the company, the preview update KB5039299 fixes issues with MSIX applications, BitLocker, Mobile Device Management (MDM), Japanese Input Method Editor (IME), Direct Composition batched presentations, and Windows Defender Application Control (WDAC).
Also, the update updates Country and Operator Settings Asset (COSA) profiles for specific mobile operators and addresses problems for apps in the jump list of the Taskbar and folder context menu.
It’s important to note that while the company has reactivated the Beta Channel and plans to release new features in the near future, Windows 10 is still scheduled to retire on October 14, 2025. After this date, the operating system will no longer receive security updates or any other form of support.
However, Microsoft plans to offer a paid subscription to allow regular consumers to keep getting security updates for up to three years after the support officially ends. The pricing of the subscription hasn’t been revealed, but for businesses, it will cost $61 per month per device, $122 during the second year, and $244 for the third year.
You can upgrade from Windows 10 to 11 right now in several ways, but only if your computer meets the minimum hardware requirements. If your computer doesn’t meet the minimum requirements, it’s still possible to upgrade unsupported hardware to Windows 11 in multiple ways.
If you want to download and install Windows 10 build 19045.4593, you have to enroll the computer in the Beta or Release Preview Channel, and from Settings > Update & Security > Windows Update, turn on the “Get the latest updates as soon as they’re available” toggle switch and click the “Check for updates” button.
Microsoft is also rolling out the Windows 11 update KB5039302 as a preview for versions 23H2 and 22H2. This update includes changes to Copilot AI, the Settings app, Share, and more. File Explorer gains a new wizard to create TAR, 7z, and Zip archival formats, and the Task Manager app is getting updated with various improvements and visual changes.
