When I try to update desktop from 8.i to win 10 I get error code 8007005.  All other updates load and install. I was able to update to win 10 from 8.1 on lap top with no problems and both machines are running identical programs. 

The fastest way to get the upgrade is to download the ISO.  An ISO is like a dvd so to use it you will need to right click>mount.  Start the upgrade from within windows.
WARNING:  DO NOT USE THESE TO DO A CLEAN INSTALL (until after you have already updated).  If you do you will not be able to activate it unless you have previously upgraded to win 10 and activated it.  You then will be forced to re-install your previous OS before upgrading to win 10

The Official Final Windows 10 download is now available Use the download tool to create ISO media to update your windows. http://www.microsoft.com/en-us/software-download/windows10 Use Download Tool Now (32bit version) http://go.microsoft.com/fwlink/?LinkId=616935 Use Download Tool Now (64bit version) http://go.microsoft.com/fwlink/?LinkId=616936
