Fittin to reboot in about 5 mikes.
Done, kept all my drivers etc
Currently backing up my files to my NAS, so have to wait.
I am trying again. It installed to 100% I rebooted went to the bathroom came back and I thought it updated but it failed. If it fails again then I don't know how to install this stupid update.
I am downloading version 1607 now at 12% at moment
Remember to run sfc /scannow on first appearance of desktop to see if there's any corruption.
Used the MCT to download the en_GB ISO. Setup.exe version is 14393. Going in for a fresh install tomorrow.
