Run Vista applications and games on XP?

[WinFreak]

When I visited one of my friends with a Windows XP computer, he had Windows Vista games and a context menu option called Run Vista Compatible when right-clicking on an .exe-file.

Where can I get that?

It would have been manually added. Also XP and Vista are both EOL and there are many known vulnerabilities. You really should be on at least Windows 7
