Serious problems files and URL sites

I am using Windows 10 64 bit OS. When I try to open photos, I get a window that reads "Illegal operation attempted on a registry key that has been marked for deletion". When I attempt to open a URL from an email, I get a window that reads "invalided value for registry. I had purchased a new Dell Laptop that had similar problems on which a Dell technician reset Windows operating system six times, and I reset it five times on my own, but the problem persisted. I finally sent the computer back to Dell in Texas, per their request to see if they can resolve the problem with that computer. But the problem that I have explained above exists on my wife's laptop that I am using until the Dell computer is returned. My personal opinion is that the Windows 10 operating system is a pile of crap. I have reset Windows 10 on this computer three times, without the problem being resolved.
