Now that they re-released it I got brave enough to try it.
Big Mistake. It messed up my sound card drivers and even a clean install would not fix it so I had to go back to a previous restore point. I made sure to turn that on and make one before installing it.
If You have a MSI motherboard with on board audio you might want to pass. I downloaded the SP3 blocker tool from MS to block it for now. It only messed up the mic, regular speaker sound was unaffected.
