The "Quick assistance from a friend" link has been added to the bottom of System > Troubleshooters.

Miscellaneous

The CIMFS device type which has been present but unimplemented since an unknown build is now implemented.
 * Therefore, the CIMFS filesystem which was present since an unknown build but unusable due to requiring a device of type CIMFS which could not be created, is now usable.
 * An attempt to create or open a device of type CIMFS will wipe all derived BitLocker keys and cap PCR11 if it was not already capped.
