);

This method sets the specified device property. To obtain the list of supported device properties, the client should query the g_wszWMDMSupportedDeviceProperties property by calling the IWMDMDevice3::GetProperty method.

For the list of device property names, see Device Properties.

This method is similar to the SetMetadata method for storages, but this method can set only one property at one time.

Not all properties of the device can be set.
