1. Make a copy of the Searches folder.
2. Run ccleaner (i.e. wait till it's next day).
3. Compare the copy of the Searches folder with the new situation.
If things have disappeared, ccleaner cleaned them.
CCleaner is configured to clean out MS Search. There is a folder called Searches on my HD loaded with search items. Is the MS Search that CCleaner clears every night the same as the Searches folder? From what I understand, the Searches folder on the HD regenerates itself when there is deletion.
Thanks for your patience everyone.
