- Microsoft has released Windows 10 build 19045.6276 as the preview for the September 2025 Patch Tuesday update for version 22H2.
- It introduces stability fixes as well as a new networking and backup feature.
Windows 10 build 19045.6276 (KB5063842) is now available as the first preview of the September 2025 update in the Release Preview Channel. The update includes bug fixes and adds new networking and backup features for commercial customers.
According to the official notes, build 19045.6276 for Windows 10 adds a new feature to block outbound network traffic for the keyless Commercial ESU solution and makes available the new Windows Backup for Organizations feature.
The Windows Backup for Organizations is a new experience that allows businesses to change devices using enterprise-grade backup and restore.
In addition, the company is pushing various fixes. For example, supplementary characters now render correctly in textboxes, resolving display issues that affected certain languages and symbols.
The “md.dll” component now properly enumerates redirected webcam devices in Remote Desktop Services (RDS) environments, restoring expected functionality for remote multimedia use.
Narrator now correctly identifies the “Enhance Facial Recognition Protection” checkbox, improving accessibility for users relying on screen readers.
The “Ask to Use” approval flow now triggers as intended when blocked apps are accessed. The Removable Storage Access policy now functions reliably, ensuring consistent enforcement of device access rules. Extended characters in the Chinese Simplified Input Method Editor (IME) no longer appear as empty boxes, and the Windows Search pane now displays the preview pane correctly.
Finally, this flight updates the Country and Operator Settings Asset (COSA) profiles, which have been refreshed to improve mobile network compatibility and configuration.
Microsoft never defines the name of an update when it’s available in the Release Preview Channel. When the updates are ready for the Stable Channel as a preview, they’ll be known as a non-security update. It’s not until they become fully available during the Patch Tuesday Update release that the company will label them, for example, in this case, as the “August 2025 Security Update.”
Installation process
To download and install this quality update for Windows 10, open the “Windows Update” settings, enroll in the Release Preview Channel, turn on the “Get the latest updates as soon as they’re available” option, and click the “Check for Updates” button. It’s important to note that it may take some time before you see the new changes on your computer as Microsoft gradually rolls out improvements.
Windows 10 end of support
Microsoft announced the end of support for Windows 10 on October 14, 2025, even though they are still releasing maintenance updates. After this date, Microsoft will no longer provide security updates, bug fixes, features, or technical support for Windows 10. This lack of updates will leave your system vulnerable to security threats and may decrease its performance.
Since the software giant will no longer provide updates or support for Windows 10, you should upgrade to Windows 11 or another operating system, such as Linux Mint, or plan to purchase a new device.
If you want to continue using Windows 10, Microsoft now offers Extended Security Updates (ESU). This service was originally reserved for organizations needing to run older operating systems beyond the official support period, but it is now also offered to regular consumers.
