The big brands and even many of the Hardware Service providers ask for Installation Charges even if they are asked to install anything which is free and even pirated. No wonder that Dell is doing this under the pre-text of Installation Charges. But then, when they sell a computer, shouldnt they be installing what is required?

Now, I wonder, if they were to install VLC media player or the others which are free, how much would they charge
