Hello,
"Winver.exe" is available in all Windows since Windows 7 or maybe since before that. Just type Winver.exe in your search box it should appear.
Anyway,
If you have Start10, it will be easier to make it transparent. You just need to disable Curtains control on Taskbar and adjust taskbar transparency via Start10.

Thank you,
