Hi Nesto,
MoI is not like most "Demo softwares". I would not worry about using your nice computer for anything to do with it... Also, it's installer is "Self contained" and doesnt scatter anything around your computer. It is all in it's own folder (accept for a license key and an ini file and we know where that is also)

I looked at your driver yesterday on the intel site, and there was a link to the previous driver posted also, to sort out a bug for something a bit different, but that is kindof a sign also...
