Windows 10: File explorer slow with loading thumnails and files

I installed Windows 10 last week as an upgrade from Windows 7, and the internet part is working good. But something with the file explorer didn't work. The Document, Pictures, Music, and Video files are still there, but the thumbnails load slowly, or not at all. If it means anything, there's a green bar that slowly moves across the top of the screen.

Help!

:)

 

Windows 10 preview pane does not show image previews

Found it.

While in File Explorer go to FILE then OPTIONS.

Then go to the View tab.

Then look for Always show icons, never thumnails under Files and Folders. And uncheck it if checked.

 

Windows 10 File Explorer Preview Thumnails

Windows 10 has changed the way the thumbnail previews in file folders look when the thumbnail previews option is enabled. In this version of Windows, the thumbnail images have been magnified compared to how they were in previous versions. So, the hundreds
of images that I set up to display as a thumbnail in a folder are now cropped on all sides. I spent hundreds of hours adding various small icons to the edges of the images that I set up to use as folder previews, and now those icons are not visible in the
thumbnails.

So here's my question: Is there a way that I can change the way Windows 10 displays the preview thumbnails back to the way it has been for at least the last 3 versions of windows?

I've tried Classic Shell, but that does not change the format. I've also tried several aftermarket file explorer type programs, and apps, but they just default to the same new "zoomed in" format. I tried making the images smaller, but no matter how small
I make them, file explorer still zooms in and crops off the edges of the image when displaying them in the folder icon.

 

Something in the recent update fixed it.

 

Step by step guide:
1. Hold Win+r to open run
2. Type msconfig and hit ok or enter
3. Click Services
4. Navigate to Windows search (you can sort the list in descending alphabetical order)
5. Uncheck tickbox
6. Click apply then ok
7. Select to restart now

Hope this works for you.
