Can't you even see that Windows XP is getting DAMN old that we've had enough of using it? It was interesting looking back then in the early 2000s but when the newer operating systems were likely to come out, it might look like I couldn't wait to try them. Nowadays, we're using the recent Windows OSes like Windows 7, Windows 8, Windows 8.1, etc. And if that's the case that Windows XP's extended support will be ending next year in April, the other editions of Windows XP may have different support ending dates such as the fact that Windows XP Embedded is living even longer than the usual Windows XP editions.
OK, it seems that Windows XP is still the most used operating system in China with Windows 7 being the second most used OS. It was a brave move for Microsoft when it comes to Windows 7 due to having done it right after the performance disaster caused by Windows Vista. Lastly, if the extended support of Windows XP is likely to end next year April, then what about Windows Virtual PC for Windows 7, then? At this rate, it will look like we're using other virtualization software like VMWare, VirtualBox, Parallels Workstation, etc. but if you do have Windows 8, you can use Hyper-V.
So, having to end support like that for Windows XP can spell security disaster for China and cause even more piracy to happen. And that's what happens when Windows XP is made way too popular until today.
