I recently uninstalled GIMP on my Vista laptop, but there is still an
Open with GIMP option on the context menu for most image file types, like JPEG and PNG. Clicking this option results in an error dialog.
Is there any way to remove it?
You can use Crap Cleaner (CCleaner) to deal with it or edit the registry for HKLM_Classes and look for the .JPG, .PNG, .BMP, there's a key in there for Open, I have given jpegfile as an example, do the same for .PNG and so on... HKEY_CLASSES_ROOT\jpegfile\shell\Open with GIMP (Backup your registry before doing this..)
Hope this helps, Best regards, Tom.
For editing context menus, nirsoft's ShellExView is both fantastic and free - highly recommended.
Locate and highlight the Gimp shell extension and press F7 (or right click on it and select Disable Selected Items).
back up registry first (to be safe) by selecting export and ticking ALL.
go to EDIT then use Find to look for all instances with "Open with GIMP"
once found, delete it then use Find next (F3) for the next one.
