Microsoft is force-installing Windows 11 25H2 on certain PCs, including those with older Windows 11 versions such as 24H2. The update is being applied to all eligible PCs, with some reports suggesting that the process is automatic and cannot be opted out of. The specifics of which PCs are affected and the details of the update process are not entirely clear, but it appears to be part of a broader effort to upgrade Windows 11 devices to version 25H2.
