Troubleshooting

Task Manager opens but shows no processes

This usually indicates a permissions issue or corrupted system file. Try the following:

• Run sfc /scannow as described in Method 3.
• Check that your user account has administrator privileges.
• Disable any third-party antivirus software temporarily and test again.

Ctrl+Alt+Delete screen is unresponsive

If the entire security screen fails to respond, the issue extends beyond Task Manager:

• Press Ctrl + Alt + Delete twice to force the screen to reload.
• Use Ctrl + Shift + Esc as an alternative to bypass the security screen.
• Restart your computer using the physical power button if the system is completely frozen.

Task Manager crashes immediately after opening

If Task Manager opens briefly then closes:

• Check for malware using Windows Security (found by searching for Windows Security in the Start menu).
• Run a full system scan with your preferred antivirus solution.
• Consider a system restore to a point when Task Manager was functioning correctly. Search for Recovery in Settings to access System Restore.

Performance remains slow after restoring Task Manager

Restoring Task Manager allows you to diagnose underlying performance issues. Once Task Manager is working, check the following:

• Review CPU, memory, and disk usage under the Performance tab.
• Identify resource-heavy processes under the Processes tab.
• Check startup programs under the Startup tab and disable unnecessary items.
