Hello, I have owned an alienware x51 gamin desktop for the past year and a half and I'm considering restoring it to factory default to enhance the performance and fix some issues. Over the years I have been actively installing many 3rd party utilities and apps that have changed system files and such. I also have manually changed system wifi settings and core settings that I probably should not have touched. Overall it would be a nightmare to undo what I have done and I feel the easiest route is to backup my games and pics and reset everything else. Now for the questions: 1. would i need to re install windows 8.1 or will that be done automatically? 2. I have Norton so would i be able to easily re install that and continue with my subscription? 3. Any risks? 4.Would you recommend any alternatives? Thank you for your help!
