Many thanks for the advice. I checked a PC with Windows 7 for x64-based Systems, and discovered the following:
Important: KB3083710 "Install this update to resolve issues in Windows." The box had been ticked. Does this mean that issues with Windows 7 will be resolved by swapping to Windows 10?
Optional: KB3035583 "Recommended Update Install this update to resolve issues in Windows."
Are these really as dishonest as they appear to be? Like others, I have been trying to move over to Linux for years, for the last few using Mint.
