Normally, the Windows Image and Fax Viewer will steal associations from other image viewers, such as AcdSee, so that when you double-click a jpeg (for example) it is opened with WIFV.

Prevent Image and Fax Viewer From Stealing Associations

Edit (delete) this string:

Windows Registry Editor Version 5.00
*
[HKEY_CLASSES_ROOT\SystemFileAssociations\image\ShellEx\ContextMenuHandlers\ShellImagePreview]
@="{e84fda7c-1d6a-45f6-b725-cb260c236066}"
*
This it the actual entry, so if you want to put it back, just save the section above that is between the asterisks to a whatevername.reg file(I used notepad) then right click it and select merge.
