I, too, am holding on to AutoCad Revit Suite 2011 and Adobe CS4. I use them vary sparingly, so it's not worth the money for a subscription. It doesn't really make sense to have a subscription, if it not your part-time or full-time job.

So, my computer is still running Win 7 because Autodesk does not guarantee Autocad working on Win 10 if it's earlier than Autocad 2016. I heard a lot of people are running Win 7 in a virtual machine for their older software. Is any one doing this? I am planning to do a dual boot or Win 7 / Win 10 to keep it. 

Thanks!
