Microsoft keeps rolling out new preview builds for Windows 10 22H2, especially for those in the Insider Program. These updates give testers a chance to try out new features and help shape future releases. The focus is on stability and minor tweaks, especially in the Release Preview Channel, which is meant for final testing before a big update goes live.

Recent Windows 10 22H2 Preview Updates

The latest build, 19045.6388, was released on September 11, 2025. It’s available for testers in the Release Preview Channel. Microsoft describes this update as containing small improvements and fixes to enhance the overall experience. These types of updates usually include stability patches, security fixes, and small feature tweaks.

Before that, several other builds have rolled out, each bringing minor new features or bug fixes. For example, in August 2025, build 19045.6276 introduced Windows Backup for Organizations, making it easier for enterprise users to transfer devices without losing data. It also fixed bugs like one that caused web camera devices to not be detected in Remote Desktop environments.

Another update in July 2025, build 19045.6156, added support for deploying anti-rollback protections via Secure Boot. It also addressed stability issues, such as unexpected closures of the Windows Extended Security Updates wizard after some users installed the May 2025 security updates.

Moving further back, earlier builds focused on fixing bugs that affected everyday use. For example, the May 2025 update (build 19045.5912) reintroduced the clock with seconds display and improved weather info in the calendar. The February 2025 update (build 19045.5552) fixed issues with the OpenSSH service not starting properly.

What’s New and Fixed in These Builds

Each update brings small but meaningful improvements. For instance, the March 2025 build fixed bugs with thumbnail previews in File Explorer, preventing crashes and visual glitches. The April 2024 build addressed GPU virtualization support issues in Windows Subsystem for Linux 2, ensuring better compatibility for tech users.

Security is always a focus. Several builds have included fixes for drivers with vulnerabilities, helping keep devices safe from potential threats. The updates also target stability, fixing bugs that cause apps to crash or behave unpredictably. For example, the October 2024 build improved the account management experience and fixed issues with scanner drivers not installing correctly.

Some updates introduced new features or enhancements that make everyday tasks smoother. The January 2025 update, for example, added a new calendar style and the Outlook app, making it easier for users to stay organized. It also fixed bugs related to virtual memory and app responsiveness.

Who Should Pay Attention to These Preview Builds

These preview builds are mainly for testers and tech enthusiasts who want to see what’s coming next. They are not recommended for everyday users, as they can still contain bugs. The Release Preview Channel, in particular, is meant for those who want a more stable experience before a new feature update hits the wider public.

If you’re part of the Windows Insider Program and want to try these updates, it’s a good idea to stay informed about what each build offers. Microsoft shares detailed notes with each release, highlighting new features, bug fixes, and known issues. This way, testers can decide whether to install the latest build or wait for a more polished version.

In summary, these latest preview builds for Windows 10 22H2 continue to refine the OS with small improvements and critical fixes. They show Microsoft’s ongoing efforts to improve stability and security before a major update rolls out to all users. If you like staying on the cutting edge, keeping an eye on these updates can give you a sneak peek at what’s coming next for Windows 10.
