Fix the error that JPG files cannot be opened in Windows 10. Sometimes, instead of opening the JPG file, your Windows 10 computer displays the error message “This app didn’t start”. Opening a JPG file is a simple task for a computer and can be done whenever you want.
However, an outdated version of Windows, corrupted file systems, or third-party application conflicts may prevent you from opening JPG files. Regardless of the cause, the following guide from Cepke.info will help you fix this problem.

1. Copy the JPG file and rename it
Sometimes, you cannot open JPG files because the file extension is wrong. Therefore, renaming the file should fix the problem.
Rename it and make sure to add the .jpg extension. Windows will display a message saying the file may be unusable, so make sure you copy the original file to another location before editing the filename.
Better try this method with one image to make sure it works before renaming multiple files in bulk.
2. Change file size
If you own a camera or smartphone capable of taking high-quality photos, you might enjoy taking some really sharp and clear photos. The only disadvantage is that Windows 10 may not be able to open these large files with its default application. To fix it, you can use an image editor or a web application to reduce the size of the JPG file.
3. Update the Microsoft Photos app
On Windows computers, Microsoft Photos is the default application for opening JPG files. If the application is outdated or broken, it will lead to any kind of problem and the inability to open JPG files can be one of them. Updating Windows Photos should fix any bugs, problems, or technical glitches.
Open the Microsoft Store app, click the 3-dot menu, select Downloads and updates. Then check to see if the Photos app is listed under Available Updates .
4. Change default photo viewer app
If you have a third-party image viewer installed on your computer, it may conflict with the default application and prevent you from opening JPG files. To fix it, you should change the default image viewer.
Step 1: Right-click on Start and select Settings.
Step 2: Go to Apps > Default apps.
Step 3: Click on the photo viewer under Default apps and select Photos from the list.
5. Microsoft Photos App Repair
Microsoft Photos may have stopped working properly due to missing or damaged files. In this case, you should repair the application. This has the advantage that Windows will check Microsoft Photos files and Registry entries while fixing errors, but will keep the application’s current settings.
Follow these steps to repair Microsoft Photos:
Step 1: Press Win + I to display the Settings menu.
Step 2: Go to Apps > Apps & features.
Step 3: Select the image viewing application and click Advanced options.
Step 4: Scroll down and click Repair.
If this doesn’t fix the problem, you can also reset the app. Follow the instructions above and select Reset. This will delete the application’s data from the computer. If you choose to reset the app, you’ll have to re-integrate OneDrive to sync your photos.
6. Run an SFC. scan
Corrupt files and system settings can prevent the computer from opening JPG files. Luckily, Windows has a built-in tool that you can use to fix the problem right away. SFC (or System File Checker) will find and automatically replace any corrupted files on your computer.
To use this tool, launch Command Prompt with admin rights. Then type sfc /scannow and press Enter. How long the scan takes depends on system resources, but once it’s done, the scan will display a message letting you know of any problems detected.
Restart the computer and check if the problem is resolved.
7. Open JPG files with another application
If you’ve updated and repaired the app, changed the file size, and still can’t open JPG files with the default Windows 10 app, try using a different image viewer. There are a lot of options available, and it’s likely that you already have one of them installed on your computer.
