The Task Manager in Windows 11 is an essential utility that provides control over running applications and processes. When it stops responding or fails to launch, managing your system effectively becomes challenging. Issues like corrupted system files, outdated drivers, malware infections, or incorrect registry settings commonly cause the Task Manager to malfunction. Fortunately, several practical solutions can quickly restore Task Manager functionality. Follow these detailed methods to get Task Manager back to normal in Windows 11.

Method 1: Restart Windows Explorer

Sometimes, the Task Manager becomes unresponsive due to a temporary glitch in Windows Explorer. Restarting Explorer can resolve minor issues quickly.

Step 1: Press Win + R to open the Run dialog, type cmd, and press Ctrl + Shift + Enter to launch Command Prompt as administrator.

Step 2: In the Command Prompt, type the following commands one by one, pressing Enter after each:

taskkill /f /im explorer.exe

After running these commands, Windows Explorer will restart. Try opening Task Manager again to check if the issue is resolved.

Method 2: Run the SFC and DISM Scans

Corrupted system files often cause Task Manager issues. The System File Checker (SFC) and Deployment Image Servicing and Management (DISM) tools can help repair these files.

Step 1: Open Command Prompt as administrator by searching for "cmd" in the Start menu and selecting "Run as administrator."

Step 2: Type the following command and press Enter to run the SFC scan:

sfc /scannow

Step 3: Wait for the scan to complete. Next, run the DISM scans by entering these commands one at a time and pressing Enter after each:

DISM /Online /Cleanup-Image /CheckHealth

Step 4: Restart your computer after these scans finish, and test Task Manager again.

Method 3: Update Graphics Drivers

Outdated or faulty graphics drivers can lead to Task Manager freezing or failing to open. Updating these drivers can resolve compatibility issues.

Step 1: Right-click the Start button and select "Device Manager."

Step 2: Expand "Display adapters," right-click your graphics card, and select "Update driver."

Step 3: Choose "Search automatically for drivers" to let Windows find and install the latest drivers.

Step 4: Once the update completes, restart your system and check Task Manager functionality.

Method 4: Scan for Malware

Malware infections can disrupt system utilities, including Task Manager. Use Windows Security to scan and remove threats.

Step 1: Press Win + I to open Settings, navigate to "Privacy and security," and click "Windows Security."

Step 2: Click "Virus & threat protection," then select "Quick scan" to begin scanning.

Step 3: After the scan completes, remove any detected threats and restart your computer. Check Task Manager again afterward.

Method 5: Enable Task Manager via Registry Editor

If Task Manager is disabled through registry settings, re-enabling it can resolve the issue.

Step 1: Press Win + R, type regedit, and press Enter to open the Registry Editor.

Step 2: Navigate to the following path:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System

Step 3: If you see the DisableTaskMgr key, double-click it and set its value to 0. If the key doesn't exist, right-click the right pane, select "New" > "DWORD (32-bit) Value."

Step 4: Name it DisableTaskMgr, and set its value to 0.

Step 5: Restart your PC to apply changes and test Task Manager.

Method 6: Perform a System Restore

If recent changes caused Task Manager issues, restoring your system to a previous state can fix it, assuming you have set up a restore point earlier.

Step 1: Search "Create a restore point" in the Start menu and open it.

Step 2: Click the System Protection tab at the top and then click on "System Restore" before selecting a restore point when Task Manager was functioning correctly. Then, follow the on-screen instructions to complete the restoration.

Step 3: After the system restore, your PC will restart. Verify if Task Manager is working properly.

Method 7: Reset Your Windows PC

If none of the above methods work, resetting your Windows 11 PC is a reliable option. This process reinstalls Windows without removing your personal files.

Step 1: Open Settings with Win + I, navigate to "System" > "Recovery."

Step 2: Click "Reset PC" on the right.

Step 3: Choose "Keep my files," follow the prompts, and allow Windows to reset.

Once the reset completes, Task Manager and other system tools should function normally again.

With these detailed methods, you can effectively resolve Task Manager issues in Windows 11. Always remember to keep your system updated and regularly scan for malware to maintain optimal performance.
