Iv'e only just got W10 and sofar Google Earth, CrystalDiskinfo and Malwarebytes work ok. I have just successfully resized C and created D using MiniTool partition wizard. Device manager shows everything fine including the USB3 card. All of the favorites in IE11 are present. This is a clean load on an Asrock 880gmh/u3s3. Sofar I have not been able to put W10 on my Gigabyte 970A-DS3 or my Asus M4A87TD EVO.
