General

What is CyberManager?

CyberManager is an ultra-lightweight, virtualized task manager for Windows. It handles 3000+ processes at 144fps with zero lag, using native NT API calls.

Is CyberManager free?

Yes. CyberManager is free and open source under the GPLv3 license.

Does it replace Windows Task Manager?

No. CyberManager runs alongside Task Manager. Press Ctrl+Shift+Esc for Task Manager, Ctrl+Alt+M for CyberManager.

Why is CyberManager faster than Task Manager?

CyberManager uses UI virtualization (only renders visible rows) and direct NT API calls, avoiding the overhead of WMI or Performance Counters.

Process Management

How do I end a process?

Select a process and press Delete, or right-click → End task.

What is "End Tree"?

End Tree terminates the selected process and all its child processes.

Can I suspend processes?

Yes. Right-click a process → Suspend. Resume later with right-click → Resume.

Why would I suspend a process?

Suspending pauses a process without terminating it:

• Freeze unresponsive apps
• Temporarily stop background tasks
• Resume when needed

How do I change process priority?

Right-click a process → Set priority → Choose level. Requires elevation for some priorities.

Search and Filter

How do I search processes?

Click the search box or press Ctrl+F, then type to filter by name, PID, or path.
