New Operating System

Yesterday, I spent nearly a whole day to change my Operating System.
But at last, there was no spare space in C dick. So I must to install the Operating System again at another disk.
This morning, I formated my D disk with near 13 G. And then I installed every software.
During the installing, I clean up all my documents.
Right now, the installment has been finished and I change my desktop theme.The new theme is cool.

Good tool is the good foundation of my other work. And I will do my best from now on!
