Windows 8 isn't activated.

Hi guys! 
I have re-installed windows 8. 
W8 is already installed but I don't accept any password. 
And it's very annoying because a screen appears every few hours to activate. 
Can anyone help? 
Thank you in advance. 
Greetings,

Hi,

Did you use the included Activator?
If not, please read the instructions that came with the torrents on how to do that.

Sure! 
As soon as the screen appears I will take a picture and I will show you it.

I haven't used Activator, I just installed W8, I introduced a serial that it accepted me, but when I start W8 the screen appears. I can use W8 but this screen appears again and again.
Can you tell me what torrent do you mean? In this page? 

I had this W8 (pirate) on a disk in my house (without serial).

Thanks for the answers! And sorry for my English.

Hi,

So you didn't install the Games4theworld Windows 8.1 torrent?

No, my version isn't of this website. 
It's windows 8. 
Perhaps there is any way to activate it without serial?

Hi there,

I've uploaded the Activator-only for you here: http://goo.gl/tvTHN2
Download it, run it as an Administrator and then use it to activate your Windows 8.
Don't forget to restart your PC afterwards!

Oh god! I Don't know how you do it but you have always the right solution!
You are the best. Thank you!
Best regards,

Hi there,

I secretly added some magic to that download, that's why!
Anyway, you're very welcome.

Anything else we can currently help you with?
