Windows 10: Slideshow error - an error is preventing this slideshow from playing

Hi, I have a specific folder in my pictures which I play screensaver slideshow from. My computer will play slideshow for a while (maybe 5 or 10 minutes), then I get the following message (white font on a black screen): An error is preventing this slideshow from playing.

How can I fix this and TIA.

An error is preventing this slideshow from playing" using windows 10 & log in screen picture

Hi

Google has given me the answer to look at settings for login screen. I have set to use lock screen settings as login screen. This is getting very very confusing, The locked screen settings is set as a picture in my pictures folder NOT microsoft spotlight,
yet I am still getting MS spotlight whenever I login

please note this is AFTER running scannow (although it reported 100% fix) and it was the same BEFORE running scannow

Don't worry, we did have backup, it's just that we are frustrated we had to resort to our backup in the first place. Thanks for the tip, though.

 

This problem has been around for nearly 10 years with some putting forth theories as to a fix, but no one really solving it. Why can't Microsoft do something about this?

 

Could there be an error/corruption of a particular file in that Folder? Or maybe there's a file that the slideshow simply can't play, wrong type or format? There's a bunch of .ini files on the HDD and can't be used, also the .thn/Thumbnail files might be a problem.
