It looks good. As others have flagged up there are a few inaccuracies, but I noped out of Windows about the time XP came out (mainly due to the product activation stuff), so I couldn't itemize those in detail.

These kind of projects are fun to do, but as a showcase of your design skills... ehhhh? There are a few things that have your original design, like your résumé and such. Something like this is a much better showcase of your front-end coding skills, but you've delegated much of that to AI.

My advice: if you want to show off your programming skills, learn how to do it on your own. Don't do Windows XP right off the bat. Start with something simple. Make an Amiga "boing ball" bounce around the screen or something. Then tackle more complex challenges. It's not just about arriving at a finished product. By crafting something yourself, without machine assistance, you develop a better feel for what should be in the finished product and what shouldn't.

(It's OK to use dumb code generators to automate repetitive tasks, transpilers, etc. But there's a feel for when and how to use those as well.)
