- Maintenance Cutoff: Microsoft plans to end OneDrive sync-app servicing on pre-22H2 Windows 10 builds on August 15, 2026.
- Support Scope: Updates, fixes, security patches, and technical help will end, but installed clients may keep working.
- Maintained Route: Windows 10 22H2 is expected to receive OneDrive sync-app updates through October 10, 2028.
- User Options: Affected users can install Windows 10 22H2, move to Windows 11, or use browser access after testing offline needs.
Microsoft plans to end maintenance for the desktop sync client on pre-22H2 builds on August 15, 2026. Feature updates, bug fixes, security patches, and technical help will end for affected PCs.
The OneDrive desktop software keeps local and cloud files synchronized so changes can appear on both the computer and cloud service. Ending maintenance targets that software rather than setting a shutdown date for cloud storage or browser access.
Installed clients may continue working, but Microsoft does not guarantee future functionality. Unsupported installations face a maintenance risk.
Release 22H2, the operating system’s final feature release, has a longer planned runway for sync-app updates through October 10, 2028. Users can update to 22H2, move to Windows 11, or use the browser-based OneDrive portal. Browser access preserves a route to cloud files, but it does not automatically maintain local copies or support offline workflows.
What the OneDrive Cutoff Removes
Microsoft will stop testing the desktop client on pre-22H2 systems on August 15, 2026. Affected systems will receive no new fixes or security patches, so future authentication, service, or compatibility changes could disrupt an unsupported installation.
Microsoft is aligning OneDrive maintenance with supported Windows releases so its engineering work can focus on operating systems still within its lifecycle. Organizations do not need tenant configuration changes, meaning company-wide settings can remain while administrators address affected devices. IT teams will need to identify pre-22H2 PCs, check application compatibility, schedule updates, and explain whether browser access meets users’ local-file and offline requirements.
Past OneDrive problems illustrate risks distinct from the planned servicing cutoff. Microsoft shipped an update that disrupted client operations in 2022, and shared folders appeared as web shortcuts instead of local directories in 2025. Those incidents involved specific faults and do not establish that unsupported clients will necessarily fail soon after August 15. Yet, long-term this could be the case.
OneDrive provides a non-sync route for users who cannot update immediately, although they must manage local copies manually. A separate change in 2026 kept recovery in the web Recycle Bin while ending delivery of cloud-deleted files to the local Recycle Bin.
Which Windows 10 PCs Keep Updates
Windows 10 22H2 was the system’s final feature release. Microsoft’s official sequence moves directly from 21H2 to 22H2 without a 22H1 version between them.
Microsoft ended support for Windows 10 21H2 in 2023. Windows lifecycle policy and the planned OneDrive cutoff are separate, but 21H2 now sits outside the maintained client boundary.
Users can identify a machine by checking its build number. Windows 10 22H2 became generally available in 2022 and carries OS build 19045, while 21H2 is build 19044.
Moving a compatible PC to 22H2 is the shortest update route, while Windows 11 offers a longer-term operating-system option. Hardware restrictions, application compatibility, or business testing may block either choice. Teams that cannot update immediately should test browser access with representative files, permissions, recovery tasks, and offline requirements instead of assuming it duplicates the desktop app.
Before August 15, administrators should choose between a maintained desktop client and a tested browser workflow that meets users’ file-access and offline needs.
