Explanation:
Manipulate Automatic Updates Behavior Using Command-line Options.
There are two documented command-line options used for manipulating Automatic Updates
behavior. These options are meant to be run from a command prompt. They are helpful for testing
and troubleshooting client computers. For comprehensive troubleshooting information for problems
with both the WSUS server and client computers, see “Microsoft Windows Server Update Services
Operations Guide.”
Detectnow Option Because waiting for detection to start can be a time-consuming process, an
option has been added to allow you to initiate detection right away. On one of the computers with
the new Automatic Update client installed, run the following command at the command prompt:
wuauclt.exe /detectnow
