❓ FAQs
1. What processes can I safely end?
You can safely end apps you recognize and don’t need (e.g., Chrome, Word), but avoid stopping system processes unless you’re sure.
2. Why is my CPU usage 100%?
This usually means one or more processes are hogging resources. Use Task Manager to find and end the culprit.
3. Can Task Manager detect malware?
Not directly, but if you see a suspicious or unknown process consuming a lot of resources, it could be malware.
4. What’s the difference between End Task and End Process Tree?
End Task kills one process. End Process Tree ends that process and all its child processes—use with caution.
5. Is Task Manager available in Safe Mode?
Yes, but with limited functionality depending on your Safe Mode options.
