After Windows 10 Update, ICloud no longer installs. Hangs at removing backup files
I was told by a Microsoft technician that if your computer had Windows 10 installed as a virtual copy to your computer as opposed to having the physical install disc and installing from disc then the iCloud installation cannot remove the the backup files as they don't exist in reality, they only exist in the virtual copy of the program.  I may not be explaining this completely accurately but the jist is that if your original set up was from the factory where they used a "photo" copy of the program data to your hard disc in lieu of doing an actual install, then iCloud will always have problems.
