Enabling the hidden option for increased translucency of the Windows 10 taskbar requires editing the Windows Registry, a crucial database which keeps track of low-level configuration options for Windows and many software applications. Therefore, exercise caution while navigating and editing the registry, and always make sure you have a current backup of all important data on your PC, as certain changes to the Registry can cause system crashes and data loss.
All of that said, you can launch the Windows Registry by clicking on Start and typing Regedit. The Registry Editor will appear in the list of results; click on it to launch the utility.
From the Windows Registry Editor, use the hierarchical list on the left side of the window to navigate to:
Once you’ve selected the “Advanced” key on the left of the window, right-click in an empty portion of the right side of the window and select New > DWORD (32-bit) value and name it: UseOLEDTaskbarTransparency.
Next, double-click on your new DWORD value and, in the box that appears, set its Value Data field to the number one (“1”). Click OK to close the value editor and then quit the Registry Editor.
Return to your Windows 10 desktop, right-click on an empty space and select Personalize. Alternatively, you can click Start > Settings > Personalization. From the Personalization section of Settings, click Colors.
Finally, from the Colors window, enable Make Start, taskbar, and action center transparent. If this option was already enabled, then quickly toggle it by disabling and re-enabling it in order for the change to take effect.
The result of the increased taskbar transparency will vary depending on your accent color choice and desktop wallpaper image, but you should see a small but noticeable decrease in opacity, removing a potential visual distraction for some users and allowing you to more clearly enjoy your desktop wallpaper image from edge to edge of your display.
If you don’t like this new “high transparency” look, just head back to the same Registry Editor location identified above, double-click on the UseOLEDTaskbarTransparency entry, and change the “1” (one) back to the default “0” (zero). Once you head back to Start > Settings > Personalizationand toggle the ‘Make Start, taskbar, and action center transparent” option again, your Windows 10 taskbar will return to its default level of translucency.
