Most used:

wuauclt.exe /UpdateNow

wuapp.exe (To show the Windows Update regular BOX you know from wihoput WSUS)

/SelfUpdateManaged
/CloseWindowsUpdate
/ShowWindowsUpdate

2003R2 Server version:

/DetectNow
/ReportNow
/RunHandlerComServer
/RunStoreAsComServer
/ShowSettingsDialog
/ResetAuthorization
/ResetEulas

/ShowWindowsUpdate
/SelfUpdateManaged
/SelfUpdateUnmanaged

/ShowOptions
/ShowFeaturedOptInDialog
/DemoUI

Most of these options don't give any noticable response, but that may be because of the state of the service. The command 'wuauclt /ResetAuthorization /DetectNow' worked for me right away.

Just type
