.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".
|
|
|
|
.PARAMETER DryRun
|
|
Preview changes without applying them
