.SYNOPSIS
    Master installation script for SolidWorks Privacy Lockdown.

.DESCRIPTION
    Runs all privacy lockdown components in sequence:
    1. Blocks telemetry domains via hosts file
    2. Disables update/background services
    3. Configures firewall rules
    4. Disables in-app telemetry via registry
    5. Verifies the lockdown

    Generates a detailed report of all changes made.

.NOTES
    Author: Atomaste Solution
    Requires: Administrator privileges
    Run this script to apply all privacy protections at once.

.EXAMPLE
    .\00-install-privacy-lockdown.ps1
    Applies all privacy protections.

.EXAMPLE
    .\00-install-privacy-lockdown.ps1 -Undo
    Removes all privacy protections and restores original settings.

.EXAMPLE
    .\00-install-privacy-lockdown.ps1 -DryRun
    Shows what would be changed without making any modifications.
