Photo gallery, movies & tv, movie maker, and store crashing/other

So basically none of those things are are working and I'd like to see if anyone can help me. For photo gallery it used to send this message "the remote procedure call failed" or something. Now it crashes with no warning; same for the store & other programs where full screen is needed to view images. I am a student so using all of these applications is priority as my project is due tomorrow. Oh, also everything is lagging even as I type and I've tried updating whatever and restarting but nothing seems to work. I have an asus transformer and windows 10. Again, help would be appreciated.
