A comprehensive batch script for managing Windows Defender in controlled educational environments. Designed for malware analysis, security research, and educational testing in isolated lab setups.
- FOR EDUCATIONAL USE ONLY in controlled environments
- ILLEGAL to use for malicious purposes or on systems you don't own
- AGAINST TOS to disable security on corporate/managed devices
- Use only in isolated virtual machines or dedicated test hardware
- ✅ Run in VMware/VirtualBox/Hyper-V with snapshots
- ✅ Disconnect from internet before testing
- ✅ Use on dedicated test machines only
- ✅ Enable logging for audit trails
- ❌ NEVER use on production systems
- ❌ NEVER connect to corporate networks
- ❌ NEVER use without proper isolation
- Windows 10/11 Pro/Enterprise (Home edition has limitations)
- Administrator privileges
- .NET Framework 4.5+ and PowerShell 5.0+
- Save script as
DefenderManager.bat - Right-click → "Run as administrator"
- Follow menu prompts for desired actions
1. Create VM snapshot
2. Disconnect network
3. Run script → Create restore point (Option 8)
4. Disable Tamper Protection (Option 6) if needed
5. Disable Defender completely (Option 1)
6. Conduct educational testing
7. Restore snapshot when done
