Can not close remote apps like Excel. Close message box loses focus.

Hi All,

We are having an issue with closing remote apps like Excel located on Virtual Machines. We can connect to and open the remote apps located on an Azure Virtual Machine using Terminal Services OK.

Since a recent Windows update, our Windows 10 users have been having issues with closing remote applications like Excel when using with Terminal Services. When the users close the Excel application the close message box loses focus and only appears when you scroll over the Excel icon on the taskbar.

This only started after a recent Windows update and only effects our Windows 10 machines and not on our Windows 7 machines.

I hope you can help
Colin
