Hi Parker,
Thank you for posting your query on Microsoft Community.
I understand that you are facing issues with Windows 10. I apologize for the inconvenience caused to you.
The issue could occur if there is change in picture settings.
To assist you better, please provide us the below information:
- When you say that "the photos on my computer" are you not able to find photos in Pictures folder in the File Explorer?
- Have you made any changes to the computer prior to the issue?
I suggest you to perform simple steps prior trying to manually copy whole pictures from Photo app and check if you are able to copy the pictures from Photo Gallery app.
1. Click on Search bar.
2. Then type "Photo Gallery" without the quotes in the search bar and click on it.
3. Check if the pictures are getting displayed in it. If it is present, then select all the pictures clicking press
Ctrl Key + A key.
4. Copy the pictures and paste it to the desired location in the computer.
