Sometimes an incorrectly configured registry may also cause this transparency issue on Windows 10 Start Menu. If that’s the case, you must correct the related DWORD key to get back the transparency effect.

Here’s how to edit the registry:

1. Use Winkey + R to launch the Run dialog.
2. Type regedit and click OK to open the Registry Editor.
3. When the User control window prompts, hit yes to authorize the access.
4. Next, browse to the below path on the left pane:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize

Or, you may copy/paste the entire path in the registry’s address bar and press Enter.
5. Move To the right side and look for the “EnableTransparency” key.
6. Double-click this entry and put “1” inside the Value data field.

7. Click OK to confirm the changes and close the registry window.
8. Restart Windows to make the changes effective from the next logon.
