I recently upgraded my home pc to windows 10 from 8.1. Every thing worked great for 3 days. Then my hard drive and screen locked up and went blank. I took it to a Microsoft repair facility I have used for the last 15 years in my little town. The end result was I lost everything. Please get a back up hard drive and save your data and back it up regularly so this does not happen to you. I lost thousands of pictures, documents , email addresses, etc. I am not the only person that 10 has done this to. Best of luck. I am going back to having a large drink to wet my sorrows. LOL.
