Hello
A company uses iPhones to take movies of on-site assessments. They burn these to CD and insert into a Windows 8.1 Pro laptop.
When they hover the mouse over a MOV file, Windows 8.1 File Explorer crashes repeatedly and the computer become unresponsive. If the file is copied to the laptop hard disk the problem is worse with repeated File Explorer crashing and the file cannot be deleted until it is renamed to .TXT
Windows Update KB2975719 causes this problem so I uninstalled it and everything is fine.
Please advise on the status of this issue, when it will be fixed and when the update can safely be re-installed.
