Turning on taskbar transparency in Windows 10 doesn’t make the taskbar fully transparent unlike in previous Windows versions. You can only enable or disable transparency but can’t change the transparency level in Windows 10. For that, you need to go for third-party utilities.
Follow the instructions below to make Windows 10 Start menu transparent with the help of Glass2K software.
Step 1: Download Glass2K software.
Step 2: Run Glass2K utility to see the following screen. Glass2K is standalone tool and doesn’t require an installation.
Step 3: Now, press the Windows logo key to see the Start menu. When the Start menu is open, use Ctrl+Shift+0-9 hotkey to change the transparency level of the Start menu. That is, for instance, pressing Ctrl+Shift+1 will make the Start menu fully transparent.
Step 4: And if you want to make the taskbar transparent, open up Glass2K Settings and adjust the same under Taskbar Transparency section.
NOTE:
a) With default settings, Glass2K doesn’t automatically load with Windows. So be sure to check Auto-load Glass2K every time Windows starts option. And also, be sure to check Auto-remember every window’s transparency settings option.
b) With default settings, when you right-click on a window or Start menu Glass2K shows a menu to help you adjust the transparency level of open window but you might want to disable it to avoid seeing the menu every time you right-click on a window.
To disable it, open Glass2K settings and then select Disabled from the drop down menu right-next to Transparency popup right-click option.
