I see the registry hack posted in
http://plugable.com/2016/01/19/flash...-7-9-m4-driver . I have not tried this yet. I would rather wait for updated driver. I reverted back to 7.9 M2 version.
I am particularly interested in M3 because this COO's computer has experienced the "Microsoft Office protected view is crashing when using hardware graphics acceleration" issue which should be fixed in M3.
