Didn't work, still can't mount ISO after the defragment.
Guess I'll have to wait for another update to fix this?
Or do you have another suggestion?
I don't think so, if you look at the site provided by Bree https://social.technet.microsoft.com...10itprogeneral
It's a bug in a security update KB4019472 ,where this problem appeared right after my cumulative update.
Users fixed the problem by uninstalling the above update. sadly I can't do that, since my update comes as a huge package -_-
