Still on Windows 10 (with a Windows 7 skin) – am I good to keep using it?

So I'm still running Windows 10, but I've got it customized to look and feel like Windows 7—start menu, theme, the whole deal. It's comfortable, it works, and I honestly just prefer the older UI.

But with Windows 10 support ending next year, I'm starting to wonder—am I setting myself up for problems down the road? Security, compatibility, that kind of thing.

I know I could switch to 11, but I'm not really excited about it. Just trying to figure out if I'm being reckless or if it's still fine to ride this out for a while longer.

Anyone else in the same boat?
