I'm dual booting both OS. Win7 because it allows me to legally watch protected premium channels (like ESPN, HBO, etc) using a TV tuner with a CableCard. And I use Win10 to watch 4K UHD with Atmos Blu Ray rips or streaming. Neither one can do the other. I enjoy Win7 more than I do Win10 and end up spending more time in it. But even though I have the extended Win7 updates from MS and even though I'm smart enough not to surf suspect websites or run suspect software... I wonder whether my local files are at more risk or not?
I think as long as you’re smart enough to not get viruses (or worse ransomware) then your personal files are safe. even newer systems aren’t safe so knowledge = safety
Yes yes yes, we all know that for sure, be smart, be careful, don't go to suspicious websites or apps. Why not give ourselves a hand? Why not add a driver to secure some folders / files with sensitive info? I do.
