I want to tell my problem that resume, at the concrete problem that my windows 8 pro i don't know what is the reason doesn't work anymore activate with these method. First of all, i activated the same windows on the same machine for more that 4 time but, now when i try to activate it give me an error that i show you imediately. I don't know what is the reason i can tell and i can assure that i follow all the corect steps: It seems that i can't show you some images.

I want also to confess that all my tries when i activated succesful this copy of windows happend when i have internet connection from another ISP, but in this moment also i change my ISP so this can be problem?
They likely took down that public server. You don't need to use public servers... Check microsoft toolkit from the projects section here on the forum. Click windows button, activation tab, select either autokms or my personal favorite KMS Server Service. Install said activator. Click activate button. Done.
