Speed up your Windows computer

Windows executes an application every day to check the compatibility of the programs on your computer. Microsoft Compatibility Appraiser runs randomly between 3 am and 5 am in the morning, and in the first 2 hours when you turn on your computer. It can use 30 – 50 % of the CPU slowing down other applications.

To disable it

  • Start the Task Scheduler
  • In the Task Scheduler navigate to Task Scheduler Library, Microsoft, Windows, Application Experience
  • Disable the Microsoft Compatibility Appraiser scheduled task
