AKAJohnDoe wroteI am seeing the entries shown in the attachment, but do not quite believe they are erroneous nor superfluous. Please advise.
As far as I can tell, everything seems to be in order.
The first item is an empty string entry under the \Run key. Such an empty entry is not valid under that key, so it's considered an obsolete entry and safe to remove.
The other items are empty registry keys under the \Software key. The \Software key should not contain any empty data, so these are also considered as obsolete and safe to remove. Although the software in question (i.e. onOne PhotoTools) might be valid and installed to the computer, the registry data is not valid and should be safe to remove.
