I tried 3 times to shut down and the open in safe mode without success.
I was tapping F8 continuously but it always opened into the password but I still kept tapping F8 but opened as normal.
the sound disruption is immediate now , distorted and intermittent
frankly having just bought this W8 for my wife I just cannot find anything that you ask, I use A mac and was on XP like my wife. I Know where msconfig was on XP but just spent 15 mins here and no luck. a complete mystery.
