What prerequisites are required to disable Windows Defender real-time protection via the command line, and how can I achieve it?

Disabling real-time protection via command line requires **TrustedInstaller privileges** and that **Tamper Protection** is disabled. The command is: `reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Real-Time Protection" /v "DisableRealtimeMonitoring" /d 1 /t REG_DWORD /f`. Tamper Protection status can be checked with `reg query "HKLM\SOFTWARE\Microsoft\Windows Defender\Features" /v "TamperProtection"` (value 5 = enabled, 4 = disabled). For obtaining TrustedInstaller privileges, tools like AdvancedRun can be used as noted in the article.
