When you are closing, opening or minimizing windows, animation effects are rendered (I guess to make it look more dramatic). I can live without those animation effects, and if you are like me, you can turn off unnecessary animations by following these steps:
- Open the Control Panel and click on Ease of Access Center.
- Scroll down and click on Make it easier to focus on tasks.
- Scroll down again and check the option Turn off all unnecessary animations
- Apply the changes
