Are you running PowerChute Personal Edition v2.0? Although dated 2005 12 20, it was released just last week and is supposed to clean up some issues. It may not help but shouldn't hurt.

If you have Win ME, you're eligible for the upgrade version of Win XP which should not cost more than $100 (and is often on sale). Note: If you want to do a clean install with the upgrade version, you supposedly need a retail Win ME CD (not just an OEM restore disk) during the install but I found this isn't always the case, e.g., Dell's restore disk seems to be accepted in lieu of a retail disk.

Cypherix Cryptainer LE is free, full featutre versions cost. http://www.cypherix.com/

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).

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.

.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?

I checked a random sample of those extensions in your screenshot. They appear to be QuickTime downloads, games, etc. Are you downloading music or playing games on the internet? If so, cleaning them is pointless ... the file types will be re-registered each time.

If you are using Win XP with System Restore enabled, the 4th folder to check is System Volume Information. The default allocation of 12% X 74.5 GB = 8.9 GB.

What OS are you using and did you have Show hidden files and folder enabled and Hide protected operating system files disabled when you searched for the files?

Whether or not a file type is still in use, you can stop it from being listed in the right-click > New menu. Use regedit and, in HKEY_CLASSES_ROOT, underneath the file-extension key for that file type, delete the ShellNew key. Change takes effect on reboot.

If you are hesitant, try selecting one category of items at a time and use Analyze to see what gets selected for deletion. Nothing will be deleted until you hit Run Cleaner. With Issues, even after you hit Fix selected issues, it offers an explanation for each item it selects for deletion and gives you another chance to decide (and as lokoike pointed out, you can backup the registry items anyway).

You may be able to recover the deleted files using recovery software such as Restoration 2.5.14 (free at various download sites). Until you run the recovery software, don't do anything that might overwrite the freespace on that drive.

??? When you clean your cookies the list should clear. Only the ones on the "Cookies to Keep" side should remain listed.

I think you have to disable "run ccleaner when system starts" after you install software that requires a reboot. CCleaner is probably wiping executables from a temp file before they're run to finalize the install. You should be able to re-enable afterwards. I have no idea what it may have done to the stuff you've already tried to install.

As far as I know, it does. The problem is probably that the uninstall didn't remove the registry key that CCleaner uses to detect the application. Open C:\Program Files\CCleaner\winapp.ini and find the entry for Paint.NET, "Detect=" indicates the registry key that causes the app to be listed. Use regedit or your preferred registry editor to find and remove that entry from the registry.

In winapp.ini it appears to check: [Office XP] Detect=HKCU\Software\Microsoft\Office\10.0\Common [Office 2003] Detect=HKCU\Software\Microsoft\Office\11.0\Common for the applications.

There isn't an overall "restore to original location" but you can: Select a batch of recovered files that were in the same location, then click "Restore by Copying". On the Save As panel, select the original location for your "Save in:" location. You'll get a warning recommending you copy to another location ... "Do you want to continue?" Click Yes.

Most major brands provide software but not all include it with the drive. Have you checked the manufacturer's website?

Restoration 2.5.14 may be useful (free at various sites). Because it doesn't install (runs from floppy or USB memory stick) it minimizes the chance of overwriting the files you are trying to recover. The default setting is to copy to a new location but you can override and restore to original location. If you've been using the computer, there's a good chance that some of the recovered files could be damaged. You may be better off reinstalling.

With the latest revision, it remembers the last folder used ... which is effectively the same as being able to set a default.

I'm not sure if this is what you want but see http://www.hmonitor.com/

It cleans the files or folders you specify. See Beginner's Guide http://forum.ccleaner.com/index.php?showtopic=1504

Pardon me but you were part of this thread: http://forum.ccleaner.com/index.php?showtopic=3343 In any case, those who clean Prefetch know the effects; those who don't theorize.
