Preserving an installed programme
I am running 6 Windows 10 machines and on those machines is a specific software that cannot be reinstalled as the company who wrote the program no longer exists. My concern is that should something happened to the machine, or it needs replacing I'm in an awkward situation.
I am looking if this software would clone my C drive on to a USB drive and should the worst happen I can install a new drive C drive and then reinstall the clone Drive onto it. Or would it be more practical to add a second hard drive internally say D, to the machine then clone C onto that one, thereby if the C drive fails, I can make the D drive the new C drive, if you understand what I mean.
I have tried cloning the C drive onto an external USB drive with the free program, but it doesn't seem to work maybe it doesn't do a full genuine clone. Can anyone please give me advice on this as I don't seem able to telephone tech support to discuss this thoroughly thank you
