I am thinking about upgrading and am wondering if V5 is working 100% in Win10. I see there is a small license problem with the upgrade that can be fixed, but I may also want to do a clean install. Would my V5 license work in that case? OTOH, I only do full image backups, should I just use V6 free with Win10 and eventually upgrade from V5 if I need the full version of V6? TIA!
