Microsoft defines "substantially different" hardware differently for PCs that are configured to be dockable. Additionally, the network adapter is given a superior "weighting." If the PC is not dockable and a network adapter exists and is not changed, 6 or more of the other above values would have to change before reactivation was required.
Dockable PCs are treated slightly more leniently. In a dockable PC, if a network adapter exists and is not changed, 9 or more of the other above values would have to change before reactivation was required. If no network adapter exists or the existing one is changed, 7 or more changes (including the network adapter) will result in a requirement to reactivate.
