Log:
[SETUPAPI]
Store the module handles to loaded property page provider dlls in the DeviceInfoData (for
class property pages) or in the DeviceInfo (for device property pages). The dlls are
unloaded when the device info set is destroyed. These dlls were unloaded as soon as the
property sheet data had been retrieved. These property pages could not be added to a
property sheet because unloading the dll invalidated the page reources.
