In the Settings app of Windows 10, a single switch controls the transparency of the three elements namely Start Menu, Taskbar and Action Center . These elements are slightly transparent by default. To manage transparency: Go to Settings > Personalization > Colors and toggle the Transparency effects to ON. However, you cannot use this setting to apply transparency to an individual UI element and retain solid color for other elements or to select the level of transparency for each of the element separately.
Control Transparency by Editing the Registry Key
You can still make the Start Menu and the Taskbar more transparent by modifying a registry key. Since the Windows 10 Registry contains settings and configurations, you must take utmost care while modifying the key. It is a good practice to take a backup of the Registry files before editing them. NOTE: You must have administrative rights on your computer to modify the Registry Key.
Increasing the Start Menu Transparency
To modify the Registry file: When you increase the transparency it is apparent when the window behind the Start Menu is lighter in color or if the wallpaper is bright. Else, the change would not be evident. Play around with bright and dark backgrounds and change the tiles pinned to your Start Menu to see what appeals to you most. NOTE: The changes made do not affect the Action Center.
Increasing the Taskbar Transparency
After making the changes, close the Registry Editor and restart your machine to reflect the changes. Alternatively, go to Settings > Personalization > Color and toggle any of the color settings, that is, toggle to Off and then back to ON to force the changes made.
Besides the above Registry trick, there are quite a few other hacks to enhance the Windows 10 system. Just be cautious and play around to make the changes. At any given time, if you are not happy with the changes made, you can always return to the original settings.
