In Lab 12 of 6294: Planning and Managing Windows 7 Desktop Deployments and Environments, we had a question about the parameters for Wuauclt. In our books, the short versions of the parameters were used.
Despite the documentation at Microsoft on the wuauclt command, the help file does not display. Here are the parameters that I have been able to find information on.
/a or /ResetAuthorization
Initiates an asynchronous background search for applicable updates. If Automatic Updates is disabled, this option has no effect.
/r or /ReportNow
Sends all queued reporting events to the server asynchronously.
Allows a client to start the detection process immediately.
Below is the list of switches that I have not been able to get definitive answers on.
Note that when combining parameters, you can use them only in the order specified as follows:
wuauclt.exe /resetauthorization /detectnow
