On the Windows 10 Fall Creators Update, Microsoft just added a newly improved interface style dubbed as Fluent Design.
It looks fancy, beautiful, and modern. Yet, it consumes quite significant GPU power. This is probably something to avoid if you still using low-end graphics hardware or battery-powered device.
Luckily, the Fluent Design wasn’t mandatory. You can revert to the ‘good old’ Flat Design easily. Check out the guide below.
1. Right-click on the desktop background and select Personalize.

2. Heads to Colors menu.

3. Scroll down and disable the Transparency effects.

From here, the essential component of Fluent Design has been disabled. But, you can disable other animations as well.
4. Go to Start Menu and find View advanced system settings program.

5. Now, click the Settings and you will see a visual effects options.

To disable entire animations, select Adjust for best performance. But please note that the option would decrease the user’s experiences as several animations also play a huge role to help a user interact with some elements.
Therefore, you can choose Custom to pick whatever animations should remain while maintaining the best performance possible. The screenshot above is one reference you could follow.
