How to Fix Task Manager Performance Tab Not Working in Windows 11

The Performance tab in Task Manager provides real-time information about CPU, memory, disk, GPU, and network usage. It is essential for monitoring system performance and troubleshooting hardware-related issues. However, some Windows 11 users report that the Performance tab is blank, not loading data, crashing Task Manager, or showing incorrect values.

This issue is usually caused by corrupted system files, disabled performance counters, outdated drivers, Windows update glitches, or permission conflicts. In some cases, system monitoring services may not be running correctly, preventing Task Manager from retrieving hardware statistics.

Fixing the Task Manager Performance tab not working in Windows 11 requires checking system services, repairing Windows components, and verifying performance counter functionality. Follow the steps below carefully.

How to Fix Task Manager Performance Tab Not Working in Windows 11

Work through each method in order and check whether the Performance tab loads correctly after each step.

1. Restart Windows Explorer

Temporary UI glitches can prevent the tab from loading.

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Locate Windows Explorer.
3. Right-click it.
4. Select Restart.
5. Open Task Manager again and check the Performance tab.

If it still does not load, continue to the next step.

2. Restart Your Computer

A full system restart refreshes monitoring services.

1. Save all open work.
2. Restart Windows 11.
3. Open Task Manager.
4. Click the Performance tab.

Minor system glitches are often resolved by rebooting.

3. Run System File Checker (SFC)

Corrupted system files can affect Task Manager functionality.

1. Open Command Prompt as administrator.
2. Run: sfc /scannow
3. Wait for the scan to complete.
4. Restart your PC.

SFC repairs damaged Windows system components.

4. Repair Windows Image Using DISM

If SFC does not fix the issue:

1. Open Command Prompt as administrator.
2. Run: DISM /Online /Cleanup-Image /RestoreHealth
3. Restart Windows after completion.

DISM repairs deeper system corruption.

5. Rebuild Performance Counters

Corrupted performance counters may cause the tab to remain blank.

1. Open Command Prompt as administrator.
2. Run: lodctr /R
3. Restart your PC.
4. Open Task Manager again.

This rebuilds Windows performance counters.

6. Ensure Performance Monitoring Services Are Running

Required services must be active.

1. Press Windows + R.
2. Type services.msc and press Enter.
3. Locate and ensure the following services are running:
   1. Windows Management Instrumentation
   2. Performance Logs & Alerts
4. Set their startup type to Automatic.
5. Restart your PC.

Without these services, performance data cannot load.

7. Update Graphics and Chipset Drivers

Outdated drivers can interfere with system monitoring.

1. Press Windows + X.
2. Open Device Manager.
3. Expand Display adapters.
4. Right-click your GPU.
5. Select Update driver.
6. Restart Windows after updating.

GPU drivers are especially important for the GPU Performance graph.

8. Check Windows Update

System bugs may affect Task Manager.

1. Open Settings.
2. Go to Windows Update.
3. Click Check for updates.
4. Install available updates.
5. Restart your PC.

Updates often fix Task Manager-related issues.

9. Create a New User Account

A corrupted user profile may cause display issues.

1. Open Settings.
2. Go to Accounts > Other users.
3. Add a new local account.
4. Log into the new account.
5. Open Task Manager and test the Performance tab.

If it works, the original profile may be damaged.

10. Reset Task Manager Layout

Task Manager layout corruption can cause blank tabs.

1. Close Task Manager.
2. Press Windows + R.
3. Delete Task Manager preference files from user settings if present.
4. Restart Windows.
5. Open Task Manager again.

This restores default layout settings.

11. Perform a Clean Boot

Background software may interfere with monitoring services.

1. Press Windows + R.
2. Type msconfig and press Enter.
3. Go to the Services tab.
4. Check Hide all Microsoft services.
5. Disable remaining services.
6. Restart Windows.
7. Check Task Manager again.

If it works, a third-party application is causing the conflict.

12. Reset Windows (Last Resort)

If the issue persists:

1. Back up important files.
2. Open Settings.
3. Go to System > Recovery.
4. Click Reset this PC.
5. Choose Keep my files.
6. Complete the reset process.

This restores system components without deleting personal data.

Final Thoughts

Task Manager Performance tab not working in Windows 11 is usually caused by corrupted system files, disabled performance counters, or service-related issues rather than hardware failure. In most cases, rebuilding performance counters and running system repair tools resolve the issue quickly.
