I can't answer your question, Pete, but what I can suggest is that before upgrading you create an "image" containing the entire contents of your "c" drive, with the image file stored on either a second internal drive or an external drive, so that you can conveniently get completely back to where you were before the upgrade if it proves to be necessary.
Windows 7's built in imaging program may be adequate for that purpose, although as with any imaging program you'll first have to create a bootable CD containing the corresponding program that would allow you to restore an image of the Windows drive or partition, should it be necessary. Note, BTW, that in contrast to 7, Windows 8, 8.1, and 10 do not include an imaging program.
Personally, though, I prefer Terabyte Unlimited's Image for Windows program, although it entails more of a learning curve than the imaging program in 7. One reason I prefer it is that it allows one to extract individual files and folders from an image. Another reason is that one can create and store multiple images created at different times, which is not possible with the Windows 7 imaging program unless each image is stored on a different drive or drive partition.
Also, the last time I researched such programs, some time ago, Acronis True Image was well regarded by many sophisticated computer users.
Finally, before upgrading you'll want to Google "Windows 10 privacy settings," which will return many articles providing information about how to change various default settings in Windows 10 that you'll want to change. Including, incredibly, a setting that by default allows Microsoft to make occasional use of individual computers to distribute Windows updates and patches to other computers via the Internet, thereby lessening the burden on Microsoft's own servers. That setting is easily disabled with a few clicks, but many users who don't take the time to explore the setting options in 10 will not be aware of its existence.
