> A faithful XP-inspired interface, custom-built to showcase my [...] attention to detail.

Here goes:

1. "Welcome" on the login screen should be lowercase

2. Balloon is too high (should touch the icon), close icon is too small (should be roughly the same height as the balloon title)

3. About Me is missing the scrollbar on Firefox

4. Wrong gradient for "Social Links"

5. Start menu should have a shadow

6. In My Projects, two tiles are loading forever

7. Windows that cannot be maximized, but can be minimized, should have all three buttons, with the middle one disabled

8. Paint did not have the Windows logo in the corner. It would be better to show the JSPaint menu bar to make things like Undo accessible, and the JSPaint authors deserve attribution.

9. "Git Co-pilot" is not a thing, as Git ≠ GitHub. (On the XP project page.)

If I were making something like this, I would probably skip the boot and login screens (certainly would not require user interaction; indeed, XP would automatically log you in if you had a single passwordless user), and show "About Me" on startup, so that potential clients don’t give up before they learn more about you.

no way, the boot and login screens add to the overall charm of the faithfulness of the reproduction, as much as does your attention to detail. In GUI applications one needs both aspects to enchant the user and keep them in a state of joyous disbelief -- without the disappointment -- as they use the system.

Also missed that double clicking the icon in the top left of the title bar closes the window. It does not toggle maximization like clicking the rest of the title bar does.

Fun-fact: that's a relic of Windows 3.1, where the close button was exactly in the top left corner of each window.

Too bad most new Windows 10+ apps don't support that anymore.
