Strange...I've been on W10 since just a few weeks after it came out, and I've had dozens of updates, etc., but never "lost" any pictures/videos/etc., as a result. Where are your pictures being stored...on your Hard Drive in a folder....or are they just in a e-mail? What are you using for a Browser...Chrome, Firefox, IE, etc.?? What are you using for Anti-Virus? As I recall, I had to do some "trial and error" for a couple of hours with W10, but the transition was pretty smooth, and over the past Year+, I have been quite satisfied with W10. If you are losing "stuff" during/after an update, I would suspect something wrong with your Windows Settings, your Browser settings, or your Anti-virus settings....cookies, registry, etc. If you haven't done so, You might try a full system scan with your anti-virus...you may have some Malware that is impacting your system.
