Method #3: Boot PC in Safe Mode
Safe mode helps to start Windows in a basic state, which uses a limited set of drivers and files. If your computer’s problem doesn’t occur in safe mode, it means that basic device drivers and default settings aren’t causing the problem. You’ll be able to observe Windows in safe mode and check if lockapp.exe is really causing high CPU or GPU usage.
To start Windows in safe mode:
1. Press Win + I keys to open settings
2. Go to update & security > then select recovery
3. Locate advanced startup then select restart now
4. On PC restarts, select Troubleshoot > Advanced options > Startup Settings > Restart
5. Wait for the PC to restart then see the list of options
6. Select 4 or press F4 to start your PC in Safe Mode
Once you’re in the safe mode, check the Task Manager to see if the lockapp.exe is running and causing a high CPU. If it is not, then there might be something else causing the lockapp.exe to cause high CPU usage on your PC.
If the lockapp.exe is still causing high CPU usage, you can stop it from running on the Task Manager while in safe mode.
