modify "Close Group" behavoir in X64?

[Guest MsFriendly]

When I choose Close Group in X64 it makes me manually open each window and

choose whether to save or close. If I have 20 instances of Notepad open

this takes forever as you can imagine.

 

Is there anyway to change the behaviour so it pops up the next instance

after I've decided what to do? I believe this was default behaviour of Close

Group in all other versions of Windows.
