Frequently Asked Questions (FAQs)
Q1: Is it safe to end all background processes?
No. Some background processes are essential for Windows to function properly. Only end processes you recognize and know are safe.

Some applications (like browsers or games) don’t release memory well. Restarting the app or your PC can help. Also, check the Startup tab for background apps.
Q3: Can Task Manager remove viruses?
It can help identify suspicious processes, but it doesn’t remove malware. Use Windows Defender or a dedicated antivirus to clean infections.
