A related topic, in that if someone is familiar enough with Win 10 and updating or moving files, they might have an answer to this question:

I am using two computers with Win 10; one doesn't connect to the Internet any more but it has some of my more expensive newer versions of software (Adobe stuff is expensive). I have an older version of Adobe in the new computer (it was on a disk and wasn't tied to the other computer so I could install it.) I still want to use the software on the old computer, but this back and forth with thumb or other drives gets old.

I picked up a USB transfer cable (Radio Shack is still in business, mostly online, and has some helpful stuff in clearance and sales) and it has a fat plug on one end so it's actually seen by the computers as a drive. The embedded software is called GO!Bridge, if anyone is curious.

To disconnect it says to click out of the folder with the corner X, and use the "Safely remove hardware" feature in either computer to remove the cable. Standard remove a drive stuff.

If I simply leave the thing plugged into the old computer and new computer, will there be any harm done? Neither computer is going to view this as a boot drive, it'll be more like a DVD drive, way down the list of things to look at for startup. Or perhaps I should disconnect it from the new computer (with the approved methods above) and leave it on the old one and plug it in when I need it?

It would be nice to have the new faster Adobe software on the new computer, but I don't have that original installation disk (it's complicated - legal, but complicated) so I go back and forth between the two. To use the current CC version of Adobe I can only get it as a download and pay a monthly fee; even at academic rates it's still a financial hit. So I'll do this for the time being.

Meanwhile, a whole new version of Windows 10 was rolled out earlier this year; mine updated automatically, it wasn't exactly a new install, but it's something people should update if for some reason they haven't already. I seem to recall that the earlier version isn't going to be supported for long.
