From the Chinese pirate masters of the non-sea-faring variety comes ... Ylmf OS! Not happy with pirating Windows XP itself, these creative Chinese have gone one step further and hacked Ubuntu to look exactly like Windows XP. Why have they moved to Ubuntu? Because their previous release -- a pirate version of Windows XP itself -- is being cracked down on by Microsoft.
If you clicked the link above, you'll notice that the entire site is in Chinese with no sign of any button that'll magically turn it into English, but if you navigate to the download page, there does seem to be five links to the ISO that you can download. Initial testing, and the screenshots, would suggest that the OS's GUI (graphical user interface) is purely Chinese too, but if you find out a way to convert it into American/English, let us know!
