Windows 11 KB5064080, the optional update for August 2025, is now available for devices running Windows 11 23H2. This update introduces the OneDrive-based Windows Backup app specifically designed for organizations, complementing the consumer version that has been accessible for some time. Users can conveniently download offline installers for KB5064080 in .msu format via the Update Catalog.
Microsoft has announced that the Windows Backup for Organizations app is being rolled out to all eligible users. Previously, only consumer edition devices could utilize this robust online backup solution, but now organizations can take advantage of its capabilities. The app securely saves user preferences, credentials, and personal files, linking them to the Microsoft Account.
Setting up a new PC becomes a seamless experience, allowing users to replicate their desktop, applications, and settings through the Out-of-Box Experience (OOBE) setup page. However, it’s important to note that the organizational version may differ slightly from the consumer edition, as administrators will have control over the setup process and the data stored in the Microsoft account.
One notable feature that remains absent is the Windows 7-like Restore function, which has yet to be integrated into this update. As KB5064080 is an optional update, users will not see it automatically downloaded and installed. Instead, they must navigate to the Settings app to check for and install the update. For those unable to do so, Microsoft has provided links to the offline installer (.msu) files on the official Update Catalog site.

The primary addition in the August 2025 optional update is the Windows Backup for Organizations. The update also addresses several bugs affecting various native system applications and features:
- The Copilot key malfunctioned, preventing the app from restarting when pressed once.
- USB devices continued to be recognized despite the application of removable storage policies.
- Performance issues arose when using SMB share on Quick UDP Internet Connection, causing delays during file transfers.
- Conflicts between the Resilient File System’s (ReFS) deduplication and compression features rendered the system unresponsive when both were enabled simultaneously.
- The Remote Desktop feature failed to recognize newly added cameras, and Wi-Fi connectivity issues occurred following a Group Policy update.
- File Explorer’s Recent section displayed incorrectly, showing only a single folder or a few folders. Additionally, syncing multiple SharePoint sites significantly impacted app performance during navigation and right-click actions.
- The “Ask to Use” approval prompt disappeared when users attempted to open blocked applications, hindering their ability to request admin unblocking.
While there are a few minor bug fixes related to Narrator and COSA profiles, no major known issues have been reported at this time. Updates will be provided should any new problems arise.
