krit86lr Posted January 29, 2006 Share Posted January 29, 2006 There are 2 registry keys that CCleaner wants to delete, but I haven't let it because I'm not sure what these keys are exactly. * Unused File Extension: WMPCD - HKCR\WMPCD (Do I want this removed? I'm guessing that it's associated with Windows Media Player. * Unused File Extension: .dmg - HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.dmg (I don't have any idea what this is, but I will do some investigating.) I also got the following error a few times, but now it seems to have stopped. I don't know why it stopped.? * Software\Microsoft\Windows\CurrentVersion\AppManagement\ARPCache\KB912919 could not be located. I don't know what I did or didn't do to cause or stop this error. Any ideas? Thank you! K Windows Pro Media 8.1 x64 | 8GB Ram | 500G HDD 7200 RPM | All that I know about my graphics is that it's Intel Link to comment Share on other sites More sharing options...
krit86lr Posted January 29, 2006 Author Share Posted January 29, 2006 * WMPCD is a Windows Media Player protocol that enables you to specify tracks on a compact disc using URL syntax. I will keep this. * .dmg is the file extension for the Macintosh disk image file. I don't have any idea why this is on my computer...Windows can't use this right?

Unsed file extensions get regenerated when a file is created with an extension that dows not have a registry entry so deleting the *.dmg is quite safe Link to comment Share on other sites More sharing options...
Greenknight Posted January 30, 2006 Share Posted January 30, 2006 Just back them up when you delete them and you can always restore them if deleting them creates a problem. Annie Brion is correct, though, deleting unused file extensions is not going to cause problems. Link to comment Share on other sites More sharing options...
Glenn Posted January 30, 2006 Share Posted January 30, 2006 I also got the following error a few times, but now it seems to have stopped.

Any ideas? CCleaner identifies that issue on my computer intermittently. ARP (Address Resolution Protocol) Cache entries are automatically created and deleted when required during network TCP/IP sessions. I've always assumed CCleaner is finding a reference to a deleted entry. You can fix them or ignore them ... the cache size appears to be very limited so they don't seem to accumulate to any significant size. Link to comment Share on other sites More sharing options...
