I used Royale Blue for ages, it was super easy to find the installer for and was signed by M$ so needed no UXTheme patch.

There was also Royale Noir and Royale Zune. Noir is a dark theme (Not to be confused with dark mode) and Zune, which was a different shade of black and sported an orange start button. Lastly there was also Royale Embedded which was a darker shade of blue, and had a blue Start button.

You wouldn’t and then

Thank you for the source! Much appreciated.
