## What it is
A Windows CLI tool that disables Windows Defender and the firewall by registering a fake antivirus through the undocumented Windows Security Center (WSC) API. It adds itself to autorun to persist the changes across reboots.

## Use cases
- disable windows defender programmatically
- turn off windows firewall from command line
- register a fake antivirus with windows security center
- bypass defender on a test vm
- re-enable defender and firewall after testing

## When to choose
- you control a Windows test environment or VM and need Defender/firewall off for research or tooling
- you want a scriptable alternative to manual Defender settings

## When to avoid
- on production or personal machines where disabling antivirus creates real security risk
- you need a supported, documented approach — the WSC API is undocumented and the project was DMCA'd
