There is a last day for Windows XP.
To memory it, here is a screenshot of Windows XP in VirtualBox.
Microsoft will release the last update of Windows XP on April 8, 2014. Then no more official updates any more.
There are still some Chinese company provide their own support to XP. As everybody knows, many Windows XP users will keep using it. They don’t want to upgrade the OS.
Windows XP is one of the best Windows OS in the whole life. I remember Window 98 is also one of the best before Windows XP came. And Windows 7 is the one of the best after it.
