Well, recently got vista and must say I'm less than impressed. Still, I'm persevering with it... One of the issues I have at the moment is that Windows Defender blocks rivatuner from starting every time windows restarts. I've been reading about this a bit and it seems the only 2 solutions are to disable UAC or disable Windows Defender!!?? Neither of which are recommended for secutiry reasons. Surely there must be a way to make Windows Defender ignore some programs (even if they are unsigned) without completely disabling it??
