I upgraded to a new computer for recording, and had Windows 10 installed. I only had it on line when loading Mixcraft and drivers for my audio interface. It is not the Win10pro.
I followed the instructions for optimizing the pc for Mixcraft and have not had any problems. I keep it off the internet, except for Mixcraft and drivers updates. I have loaded plugins with thumb drives without problems.
