Desktop Background - Windows counterfeit

Hey! I got a problem about my desktop background. It started happening since I installed "Windows Essential" but I'm not sure about that. The problem is every time I reboot my laptop, my desktop background would disappear and it would just turn to black. Before my whole desktop appears, there's a box that says "Windows Activation" and it also says that I don't have Genuine Windows and its just a counterfeit.

How could I solve this? Coz I hate the color black. Lol. Thanks in advance! :)

I'm sorry, I don't know. My bro just let his friend fixed my laptop because it was having problems with connecting to internet. ;( So, will I reinstall genuine media now?

Wait. Will my files be deleted also if I reinstall? :) And, I have a question.. If my windows isn't genuine, why did the problem occurred just these days? My laptop was fixed a few months ago. Just curious Thanks, again!
