Well, I had a few bugs with the new Windows 10. Yesterday I was changing from Spybot to Bitdefender, and had to restart after the download. When I did, it started automatic updates, and crashed my laptop. I took it to the Windows store here in Boston, and they said my hard drive crashed. They want $150 to reinstall Windows. My laptop is an HP with all the backup files on D drive. You can't even get to recovery on the thing. This is Microsoft's fault not mine. Now I am out a laptop. If anyone can tell me how to fix this, I'll just go back to 8.1. If not, I'm selling it to a friend for $50.
