I feel slightly ashamed that I spent enough time using Windows XP that was able to spot that this was a clone based on the fonts and shadow effects alone.
It could be a badge of honor! You used the system so much that clones can't fool you. To be fair, Windows text rendering does have a very specific look that's difficult to perfectly replicate without using the actual Windows APIs.
I'm sure some here could look at a screenshot of the same text rendered on Windows, macOS, and Linux and tell them apart.
Nice effort though.
