Automatic update service missing

Just had an issue when I noticed that Windows Automatic updates service was missing in Service Console. The service registry was also missing:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\wuauserv

 

One of solution known to is to reinstall the component from its configuration file. The command used:

%windir%\System32\rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 %windir%\inf\au.inf

 

Hope it helps!
