Pictures takes 20 seconds to load

Nothing else running on your PC? Clean the disks regularly with CCleaner or Wise Disk Cleaner. Are there any errors in the register? Use Wise Registry Cleaner or CCleaner's registry cleaner. There is sometimes a lot of crap on PCs with Windows OS, so I recommend checking this first. I'm also a Windows 10 user, I regularly do registry and disk cleaning and there's always a lot of junk to clean up.
