Windows 10: Windows 10 Screensaver Photos Slide Show Speed

I'm using Win10 Pro with an AMD FX6300 CPU. I was wondering if there is a registry key or some other setting to alter/slow down the slide show timer more than what it is. Right now it changes pictures about every 20-30 seconds - on the "Slow" setting. I would rather it change more like 1 every 5 minutes... Can anyone provide some input on this?

Windows 10 Screen Saver Slide Show

Windows 10 updated recently (April 2017) and I can no longer make a slide show for screen saver by going to Control Panel>Personalize>Screensaver>slide show. I can go to Settings>Background>Slideshow and choose photos, but there is no place to click on
Apply or Finish there and it doesn't get established. Also, the Background slideshow suggests that I choose as time allotment 1, 10, 30 minutes or 1, 6 hours, or one day, so it is not the same as the former Screensaver slide show that permitted various short
periods of time (in minutes). QUESTION: How can I set up a slideshow screensaver such as I have in the past, for many years?
