Remove-All-Docker-Images.ps1

<#
    Remove-All-Docker-Images.ps1

    Purpose:
    - Show all Docker images installed on Windows
    - Show image sizes
    - Stop and remove containers that may block image removal
    - Remove all Docker images
    - Run safe Docker cleanup
    - Show disk usage before and after

    This script removes:
    - Docker images
    - Stopped/running containers, if you allow it
    - Dangling build cache
    - Unused networks

    This script does NOT remove by default:
    - Docker volumes
    - Named database volumes
    - Bind-mounted project folders
    - Docker Desktop itself

    WARNING:
    If your MySQL/Postgres/Mongo data is stored in Docker volumes,
    do NOT enable volume pruning unless you are absolutely sure.

    Run:
    powershell -ExecutionPolicy Bypass -File .\Remove-All-Docker-Images.ps1
