Fix Win10 picture open without Windows Photo Viewer issue

1. Open the Registry Editor (Win+r,regedit) and navigate to (back up the registry before the proposed modification):

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Photo Viewer\capabilities\fileassociations

2. Right-click in the right-hand window, select "New – String Value", then rename the new string value to. jpg, set the value data to PhotoViewer.FileAssoc.Tiff, and follow the same method to create a new named. jpeg. png. gif. bmp. The string values of the commonly used picture formats, such as PCX. Tiff. ico, and numeric data are set to PhotoViewer.FileAssoc.Tiff.

3. Close the Registry Editor, then right-click on the image and the "Open with" menu will display "Windows Photo Viewer".

If you feel that the above operation is more cumbersome, you can also create a reg registry file to bulk add the above string value. Here's how:

1. Create a new TXT text document, copy and paste the following code into it (you can add or modify the image format code in the same format as needed):

 windows Registry Editor Version 5.00; Change Extension ' s File type[hkey_current_user\software\classes\.jpg]@= "PhotoViewer.FileAssoc.Tiff"; Change Extension ' s File type[hkey_current_user\software\classes\.jpeg]@= "PhotoViewer.FileAssoc.Tiff"; Change Extension ' s File type[hkey_current_user\software\classes\.gif]@= "PhotoViewer.FileAssoc.Tiff"; Change Extension ' s File type[hkey_current_user\software\classes\.png]@= "PhotoViewer.FileAssoc.Tiff"; Change Extension ' s File type[hkey_current_user\software\classes\.bmp]@= "PhotoViewer.FileAssoc.Tiff"; Change Extension ' s File type[hkey_current_user\software\classes\.pcx]@= "PhotoViewer.FileAssoc.Tiff"; Change Extension ' s File type[hkey_current_user\software\classes\.tiff]@= "PhotoViewer.FileAssoc.Tiff"; Change Extension ' s File type[hkey_current_user\software\classes\.ico]@= "PhotoViewer.FileAssoc.Tiff"  

2. Then rename the text document to Photoviewer.reg (or any name), and then double-click to run the Reg registry file to import the data into the registry.
