Many good questions, and no answers from developer.
So how does this program work? If one has a Windows license, you can reinstall without this. One can save all of their documents, pictures, videos by copying. One should be backing them up anyway.
The question I have is will it move installed programs to a new computer? This can be done by making a backup image of the whole disk of one machine and restoring to the new driver or computer. Some drivers may be wrong. But if this is not handling incompatible driver and moving everything about installed programs including registry entries, exactly WHAT is it doing?
