How to Fix Task Manager Not Opening on Windows

Task Manager is a crucial Windows utility that allows users to monitor system performance, manage startup apps, and close unresponsive programs. However, some users encounter issues where Task Manager refuses to open, leaving them unable to troubleshoot system problems. This issue can stem from system file corruption, malware infections, or misconfigured settings.

Why Task Manager Won’t Open on Windows

Several factors can cause Task Manager to stop responding or fail to launch:

• Corrupted System Files – Damage to essential Windows files can prevent Task Manager from opening.
• Malware Infections – Malicious programs can disable Task Manager to prevent users from terminating suspicious processes.
• Registry Errors – Incorrect registry settings might block Task Manager from running.
• Group Policy Restrictions – If Task Manager is disabled in Group Policy, it won’t launch.
• Software Conflicts – Third-party applications may interfere with Task Manager’s functionality.
