Windows 10 preview will not update due to old version of preview. I had to do a clean install of my preview once I did windows updates quit working I found I had installed an older version that had no updates installed so I installed the upgrade you would use for windows 7 or 8.1 and it worked I have a full version of windows 10 error 0x80248014 is fixed and updates are working fine. http://www.microsoft.com/en-us/software-download/windows10
