End of support for OneDrive sync app on Windows 10 22H1 and earlier

🚨 The Signal: Microsoft is ending OneDrive sync app updates for Windows 10 22H1 and older devices from August 2026. This means no more security patches, increasing vulnerability for unpatched systems and impacting data synchronisation integrity.

The Impact

Organisations with Windows 10 22H1 or older devices are at high risk due to unpatched OneDrive sync apps, leading to potential data exfiltration or integrity compromise.

• Security Teams: Increased attack surface from unpatched OneDrive sync apps on older OS versions.
• IT Admins: Operational burden to identify and upgrade vulnerable Windows 10 devices.
• End Users: Potential disruption to file synchronisation and access on unsupported devices.
• Compliance Officers: Non-compliance with patching requirements for critical applications and operating systems.

The Action

1. Identify all Windows 10 devices running version 22H1 or earlier using Microsoft Intune or SCCM.
2. Develop and execute a plan to upgrade identified devices to Windows 10 22H2 or later, or migrate to supported OS versions.
3. Communicate end-of-support implications to affected users and provide guidance on OS upgrades.
4. Monitor device compliance reports to ensure all endpoints are running supported Windows and OneDrive versions.
