Windows 11 KB5064080, an optional update for August 2025, is available for devices running Windows 11 23H2. It introduces the OneDrive-based Windows Backup app for organizations, which complements the existing consumer version. Users can download offline installers in .msu format from the Update Catalog. The Windows Backup for Organizations app securely saves user preferences, credentials, and personal files linked to the Microsoft Account, facilitating a seamless setup experience for new PCs. The organizational version may differ from the consumer edition, with administrators controlling the setup process and data storage. The update does not include a Windows 7-like Restore function. Users must manually check for and install the update via the Settings app, as it will not be automatically downloaded. The update also addresses several bugs affecting system applications, including issues with the Copilot key, USB device recognition, SMB share performance, ReFS deduplication and compression conflicts, Remote Desktop camera recognition, File Explorer display errors, and the disappearance of the “Ask to Use” approval prompt. Minor bug fixes related to Narrator and COSA profiles are included, with no major known issues reported.
