    Thank you very much dear Brink. Appreciate all your useful tutorials. Right now I have another question, though, which is somewhat related to this thread.
    Is it possible to adjust screen brightness in Windows 8 by assigning a keyboard shortcut to it? If not directly from the windows itself, maybe by using some sort of utility or a hack ?
    I have a Sony VAIO VPCEB1S1E/BJ laptop and I installed Windows 8, which is not officially supported by Sony for this laptop and the only problem I have as a comparability is to make Sony brightness control software to work on this Windows!
    Would be glad to hear from you, I hope there is some solution for this, thanks.
