1.) To disable Windows Defender, go Control Panel->Security->Windows defender->Tools->Options, then uncheck the options for automatic system scans and realtime protection.
2.) To remove unnecessary options, go Control Panel->Programs->Turn Windows Features On or Off and deselect what you don't want, then restart.
Hope this helps,
