My laptop has been running with windows 8 64 bit operating system for several months. All are going quite well. But last weekend, one of my friends borrowed my computer and she installed it with some player which I do not like to use. So I tried to unindtall it yesterday, I tried to delete it in the control panel. But I can't find it, and it appears in "Start". Whenever I want to play video, it becomes the default player. I do not know why, I can not delete it any more.
So, could you do me a favor?
