QuickKill requires administrator privileges to kill processes owned by other users or elevated processes.

QuickKill explicitly blocks killing these Windows system processes:

• csrss, wininit, winlogon, services, lsass, smss, dwm
• System, Registry, Idle

If you discover a security issue (e.g., a way to bypass the critical process guard), please open an issue with the details. We take these reports seriously.
