Windows 10: Windows 10 AU Problem

After installing Windows 10 AU, my computer only boots up to the Automatic Repair window where it gives me the choice to Restart or Advanced Options. Unfortunately whatever caused the problem also seems to have prevented power to get to my mouse and keyboard so that I cannot make any choices at all. Manually powering off/on computer only lands me back in the same place. Has anyone experienced this problem? How did you fix it?

Windows 10 Problem On Itunes, Every time i download or update my apps in itunes application it always stopped with the error: 3553

I already executed the fix "
https://support.apple.com/en-au/HT201668 " but still the problem remain. I think the problem is windows 10 operating system because when I'm using windows 8.1 i don't have a problem like i encountered now in windows 10..

 

Hi, have you tried booting from e.g. a Win 10 bootable medium - and there's a useful disk here:
Windows 10 Recovery Tools - Bootable Rescue Disk - Windows 10 Forums
When you do so, do your mouse and keyboard respond?
And can you then see your HDD? (Or is it a SSD?)

Did you upgrade Win 10 to the AU, or clean install it?
