The one with the two folders is locked (see the lock symbol) and the reason it is impossible to delete it is down to the two folders with the odd names. These are actually created by a rather special user who is now an 'unknown' user, and will probably be found to 'own' the old recycle bin. I can tell you this sort of strange thing has been happening in win 7 for at least 4 years or more with no action or solution from MS. There never will be either.
Examples of the unknown user S-1-5-21-etc.... are :- a previous administration user now replaced by a new administrator for certain reasons (computer pre-owned, or OS updated from earlier OS version), or quite commonly a user generated by backup software installed to do drive imaging and since removed from the system. Such a super-user has to have super-full rights in order to be able to image a complete drive.
Here is an example of the sort of thing people try to remove such folders which can no longer be processed. http://answers.microsoft.com/en-us/...ders-how/3160990a-e723-45dc-84e8-3e493ef57c89
I can only report that most times, nothing can be done to remove those problems, but they don't cause any futher trouble, just frustration. To complicate matters, that unknown super-user will also be found in the registry in several places.
