Windows 7 uses incorrect way of figuring out AP's WPS capabilities by acting as a Registrar and using M1 from the AP. The config methods attribute in that message is supposed to indicate only the configuration method supported by the AP in Enrollee role, i.e., to add an external Registrar. For that case, PBC shall not be used and as such, the PushButton config method is removed from M1 by default. If pbc_in_m1=1 is included in the configuration file, the PushButton config method is left in M1 (if included in config_methods parameter) to allow Windows 7 to use PBC instead of PIN (e.g., from a label in the AP).
