I've recently upgraded 8.1 to 10. Things seemed somewhat okay but before I try to do anything with programs, etc., I want to back up and also make a system image to an external drive. This will not happen, I get error codes, 0x807800c5 and 0x80780081. I do not want to resort to third party programs until I find a reason that win 10 will not allow these back ups to be made. I am in search of a solution for this.
