host-parity

About this tag
The host-parity tag on WindowsForum.com covers discussions about maintaining consistent patch levels between Hyper-V host and guest virtual machines. A key example is KB5066360, a no-restart hotpatch that fixes a PowerShell Direct (PSDirect) handshake failure caused when the host and guest are unevenly patched. This update addresses both interoperability and security regressions, raising the OS build to 26100.6569 on eligible systems. The tag is relevant for IT administrators managing Hyper-V environments who need to ensure seamless PSDirect connections and avoid disruptions from patch asymmetry.
