Windows

Create a shortcut to Windows Update on the desktop for all users.

In C:\Users\Public\Desktop, create a shortcut with the following path:

%SystemRoot%\explorer.exe shell:::{36eef7db-88ad-4e81-ad49-0e313f0c35f8}

To make the icon match, use the one located in the following DLL:

%SystemRoot%\System32\wucltux.dll

You can use this PowerShell script to automatically create it:

$WshShell = New-Object -comObject WScript.Shell
$Shortcut = $WshShell.CreateShortcut("$env:PUBLIC\Desktop\Windows Update.lnk")
$Shortcut.TargetPath = "$env:SystemRoot\explorer.exe"
$Shortcut.Arguments = "shell:::{36eef7db-88ad-4e81-ad49-0e313f0c35f8}"
$Shortcut.WorkingDirectory = "$env:SystemRoot"
$Shortcut.IconLocation = "$env:SystemRoot\System32\wucltux.dll"
$Shortcut.Save()
