Hi
Every Registry scan, CCleaer find this:
Problem Data Registry Key
Unused File Extension {80b8c23c-16e0-4cd8-bbc3-cecec9a78b79} HKCR\{80b8c23c-16e0-4cd8-bbc3-cecec9a78b79}
I think CCleaner can't fix it :/
Maybe CCleaner have to delete the folder {80b8c23c-16e0-4cd8-bbc3-cecec9a78b79} or it's a windows-bug. If this a windows-bug, CCleaner should it automatically add to the exclude list.
My system:
MS Win XP Professional 32-bit SP3
But I saw this 'bug' also on other PCs (XP & Vista)
