    .SYNOPSIS
        Configures Windows Update using simple GUI-equivalent settings
        
    .DESCRIPTION
        Applies 3 simple Windows Update settings that align with the Windows Settings GUI:
        1. Get the latest updates as soon as they're available (ON, enforced via policy)
        2. Receive updates for other Microsoft products (ON, user-toggleable)
        3. Delivery Optimization - Downloads from other devices (OFF, enforced via policy)
        
        NO forced schedules and NO auto-reboot policies are configured.
        Installation timing remains user-controlled via the Windows Update GUI; where
        policies are used, Windows clearly indicates that "Some settings are managed
        by your organization".
