From batch file or shortcut: start Windows Update (via: Windows 7 Help Forums)

Call either of these from a batch file or Windows shortcut to end up at the Windows Updace screen in the Control Panel:

%windir%\System32\rundll32.exe url.dll,FileProtocolHandler wuapp.exe
%windir%\explorer.exe shell:::{36eef7db-88ad-4e81-ad49-0e313f0c35f8}

Notes:

• I’ve tested this in Windows 7, 8.x and 9 and it works fine in all these.
• unlike Control Printers calling Control Updates does not work.
