YES IT DOES! I have GroupWise 8 and 6.5 clients running on win 10 machines. Sometimes people just read a book and the rest of us just do it.
It is Dec 2020 and I am still running two Netware 6.5 servers, one for only file services, the other running GroupWise 6.5 about to upgrade to GroupWise 8 .
I think that is a clear task for Desktop Container. I have to support many different GroupWise versions - even GroupWise 8. So I create different versions of Desktop Container - each contains a special version of GroupWise. That's the way how I can start the right version of client for each purpose.
There is one more advantage especially in times of home office - you can run and use your GroupWise client without installing software on your private PC.
