## What it is
defendnot is a C++ Windows utility that disables Windows Defender by registering a fake antivirus product through the Windows Security Center (WSC) API. It runs as a loader binary or PowerShell one-liner and can optionally register a fake firewall and strip additional Defender policies.

## Use cases
- disable windows defender on my machine
- register a fake antivirus via WSC api
- turn off defender real-time protection programmatically
- remove windows defender from security center
- security research on windows defender tampering

## When to choose
- you need to disable Windows Defender on a Windows machine you control, e.g. for testing or lab environments
- you want a WSC-API-based approach rather than registry or service hacks
- you want optional extras like fake firewall registration and extra Defender policy stripping

## When to avoid
- you need a legitimate antivirus solution or endpoint protection
- you cannot or will not temporarily disable tamper protection and Smart App Control first
- you need the tool to survive reboots without keeping binaries on disk
- using it to facilitate malware distribution or any illegal activity
