My thumbnail views in windows explorer no longer display. For years I have
used Irfanview as my default viewer. It used to quickly display my jpeg
files in the windows explorer. All I get is the Irfanview icon. I can't seem
to troubleshoot the problem. Any ideas?
 
Solved.
Exported a good key from one image format, edited it in notepad, and
imported to replace the bad image format keys.

This is the reult of letting imaging programs associate images to themselves. That in itself is not bad only many remove the Shellex key that is responsible for showing the image preview in Windows Explorer:

HKEY_CLASSES_ROOT\.jpg\ShellEx

and it's subkey:

HKEY_CLASSES_ROOT\.jpg\ShellEx\{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1}

which is what is responsible for the image preview.
