Why Efficiency Mode Not Working in Windows 11?

Before diving into fixes, let’s identify the potential culprits:

Compatibility Issues: Not all apps play nicely with Efficiency Mode. Some may be incompatible due to outdated drivers or inherent resource demands.

Fix Efficiency Mode Not Working in Windows 11

Now, let’s equip you with the tools to fix the problem:

1. Check App Compatibility

  • Identify apps experiencing issues with Efficiency Mode.
  • Update their drivers to the latest versions from the manufacturer’s website.
  • Consider excluding specific apps from Efficiency Mode if necessary (see steps below).

2. Run System File Checker and DISM

  • Open Command Prompt as administrator.
  • Type sfc /scannow and press Enter. This scans and repairs corrupted system files.
  • After completion, type DISM /Online /Cleanup-Image /RestoreHealth and press Enter. This repairs potential image corruption.
  • Reboot your system after both scans are complete.

3. Check Background Apps

Go to Settings > Apps > Features > Advanced Startup options. Uncheck any apps you want to run permanently in the background, overriding Efficiency Mode.

4. Disable Battery Saver

Disable Battery Saver mode (Settings > System > Battery > Battery saver) as it might restrict resources used by apps, impacting Efficiency Mode’s ability to optimize.

5. Disable Third-party software

Temporarily disable any third-party system optimizers or task management tools that might interfere with Efficiency Mode.

6. Performance Bottlenecks

Monitor resource usage (CPU, RAM, storage) using Task Manager to identify potential bottlenecks. Upgrade hardware or optimize resource-intensive tasks if necessary.

7. Malware Scan

Run a thorough malware scan with your preferred antivirus software to eliminate any potential infections hindering system performance.

8. Update Windows 11

Ensure you have the latest Windows updates installed (Settings > Update & Security > Windows Update) as they often include bug fixes and performance improvements.

9. Create a New User Account

Create a new local user account to see if the issue persists only in your current profile. This helps isolate user-specific configuration problems.

10. Reset This PC

As a last resort, consider resetting your PC (Settings > Recovery > Reset this PC). Choose “Keep my personal files” to retain data but reset system settings and apps. Back up important data before performing this step.

11. Manage Efficiency Mode Manually

Remember, you can manually manage Efficiency Mode for individual apps:

1. Open Task Manager (right-click taskbar > Task Manager).

2. Find the app in the “Details” tab.

3. Right-click the app and select “Set Efficiency Mode” > “Normal” or “Efficient.” “Normal” prioritizes performance, while “Efficient” minimizes resource usage.


By understanding the causes and applying the solutions outlined above, you should be able to overcome Taskbar Efficiency Mode malfunctions in Windows 11. Remember, patience and a systematic approach are key. If the issue persists even after trying all these steps, consider seeking help from Microsoft support or a qualified technician. Happy multitasking!
