Windows update client name - wuauclt.exe

i allways findit hard to remeber the name of the windows update client file name so i can lunch it and force an update check so i search the internet to find more detail about his name;
from what i manged to find, wuauclt, stand for Windows Update / Automatic Updates CLienT

i also found more option to use for this application:

/DetectNow – force a search for updates
/ReportNow – forces a Report to the WSUS server
/UpdateNow – Triggers a forced update event
