How do I change the transparency in Windows 10?

You can change the transparency in Windows 10 through the Settings app. Here's how:

1. Open the Settings app: You can do this by clicking the Start button and then clicking the gear icon.
2. Go to Personalization: In the Settings app, click on "Personalization."
3. Select Colors: On the left-hand menu, select "Colors."
4. Toggle Transparency Effects: Under "More options," you'll find the option "Transparency effects." Toggle this switch to the "Off" position to disable transparency for the Start menu, taskbar, and action center. Toggle it to "On" to enable transparency.

By turning off "Transparency effects," you will remove the glass-like look from the Start menu, taskbar, and Action Center, making them solid colors.
