I recently tried to add a wireless connection on a friend's Chinese laptop running Vista. I couldn't switch the interface language, so I decided to Google how to do it and attempt to follow the pictures. But for some reason, I just couldn't find the "Network and Sharing Center" that it was talking about. I found something that looked like XP's Control Panel, but couldn't understand enough of the Chinese to setup the connection. I had only used Vista for about 30 seconds total prior to then, and I found it awfully odd that it looked so much like XP, but with better icons. So like a good engineer, I rebooted. The first screen that came up was the Windows XP loading splash screen. Hmm, odd. Right after that, the Vista splash screen came up. It logged in, and the background and icons are Vista-fied.
Chinese "Vista" is XP with a Vista skin. Sometimes getting ripped off ain't so bad. =)
