Microsoft now force upgrades unmanaged Windows 11 24H2 PCs
Summary
Microsoft has begun automatically upgrading unmanaged Windows 11 24H2 Home and Pro devices to Windows 11 25H2. This move aims to ensure devices are running supported versions of Windows and to patch security vulnerabilities.
IFF Assessment
This is good news for defenders as Microsoft is proactively updating systems to patched and supported versions, reducing the attack surface.
Defender Context
Defenders should be aware that Microsoft is pushing updates to unmanaged devices. This can be a positive for baseline security but also a disruption if not managed properly, potentially leading to unexpected compatibility issues or downtime if specific configurations are required. It highlights the importance of maintaining visibility and control over endpoints, even those considered 'unmanaged'.
