People here can say that asking Microsoft to supporting XP is ridiculous. 

I'm not saying it's ridiculous. I'm just saying it's not going to happen. XP is dead. The Microsoft board has spoken.

Assuming you have a standard split of the demographic, it means that 1/4 of your income comes from people running XP. 

But not 1/4 of Microsoft's customers. The people on XP stopped giving their money to the residents of Redmond many moons ago, and hence they no longer enjoy the support of Microsoft.
