So I got my Windows 8 computer in 2012, later upgraded it to 8.1. I have had no major problems with it until earlier today. I have Sony Vegas Movie Studio and when I tried uploading a video into it to edit it, my computer started freezing at everything. I looked in my task manager and it was nothing major to the RAM or CPU. I tried restarting it and then upon restarting, it showed a black screen with nothing. I had to restart it 5 times to get it to actually turn on. This post is not about malware issues or freezing though.
I want to reset my computer to factory settings. So I go to Settings-->Change PC Settings-->Update and Recovery-->Remove Everything and Reinstall Windows. And it gives me this message: "Some files are missing. Your windows installation or recovery media will provide these files." So I looked it up and found this site: http://www.gizmag.com/how-to-windows-8-pc-refresh-reset/32801/
Towards the end of the page it says what to do if you get that message. So I followed the commands and waited until it was 100% completed. Then I was happy and tried resetting it again. I get the same message.
So my question is: How do I reset my computer? And pardon the long post.
