Minimizing & closing multiple grouped windows from taskbar

Question

On Windows Server 2012 R2, I have set my taskbar to combine buttons. I have multiple instances of a console application running, and they combine on the taskbar fine. However, when I right-click on the combined button, I only get a list of window names,
each with a "close" button. I no longer have the option to "cascade", "minimize group" or "close group" like on my previous version of Server. So I tried opening a bunch of browser windows also, and I can right-click
on that combined button and at least get "close all windows", but still no "cascade" or "minimize". So for now, my workaround to minimize is to just show desktop. But I could really use a shortcut to "close all" since
I have 14 of these windows that I close pretty often. What is it about my console application that would have Windows Server 2012 omit that "close all" option, when I DID have that option with the same application on the older version of Windows
Server?
In addition, I saw a tip somewhere else to simply CTRL-select the processes in Task Manager and close them all that way, but I can't even do that. I can't select multiple items in the Processes or Details tabs of Task Manager with either the CTRL or SHIFT buttons.
I wasn't able to do that on my older server either, so strange that that's an option for some people.

Hi LysR777,
Do you mean the "cascade all windows", "Minimize Windows" option cannot be found?
If so, Please try to Hold the SHIFT key and then right click on the Stack of combined taskbar items, the screenshort below on server 2012 R2 is for your reference:
If there is anything else regarding this issue, please feel free to post back.
