Class Method Details

.connect(uri = nil) ⇒ Object

returns a COM class implementing ISWbemServicesEx prior to Facter 2.5.0, this defaulted to using a moniker but now defaults to using COM classes directly to support Nano backward compatibility is maintained in case custom facts specified a moniker but note that passing in the uri parameter can never work on Nano
