Hi:
Everytime I run a registry scan the same problem comes up, namely:
"Invalid File Extension". Registry key: HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.nef.
It didn't happen before. Is it a bug?

.nef is the extension for a Nikon digital camera image file. Do you have a Nikon or might you have saved an image file at some time?
Yes, I have. I've recently bought a Nikon digital camera and installed the software it came with.
I suspect that when you connect the camera (or its memory card) and/or use the related software to view or edit, the file type is re-registered. So clearing it is probably futile and you should probably just ignore it ... unless one of the other forum members knows how to tweak the registry or CCleaner to not select the specific extension.
CCleaner to not select the specific extension.
The only way for that to work would be for an ignore list to be included with CCleaner.
I'm not sure but you may have to keep at least one .NEF file on your harddrive (but not in a temp folder which will be cleaned) to keep CCleaner from wiping the file type entry.
If that doesn't do it, this isn't a very elegant solution but:
You could use Explorer > Tools > Folder Options > File Types and manually add NEF to the list.
If you don't have an application to open that file type (although your Nikon software should) I believe you can add and set a harmless default action like Open with Notepad, then delete the action to make "no action" the default.
Alternatively, you could get a viewer (e.g., FastStone has several freeware apps).
Thank you very much, Glenn. I'll try your suggestions.
