Why does my windows explorer not show thumbnails?

Question

When I used to open a file with photos I used to get very useful thumbnails, now I only get icons. How do I change it back?

I have checked the file properties and it is set to Photos and movies...

Answer 1

Open any folder in windows go to extra/organise, click "Folder Options". Under the "Files and Folders" tab, uncheck the box next to "Always show icons, never thumbnails".

Click the OK or apply button.
