Bulk Rename Utility

I have downloaded the utility but I am not smart enough to use it. I am trying to rename files with naming convention of.
FROM THIS number_yr-filenumber_Firstname_Lastname-full-casefile.pdf" TO THIS Lastname, Firstname yr-filenumber So I want to eliminate the number and underscore before yr and then change order as shown along with Caps on first character of last and first name. All files will be like this Smith, John 2020-580 with an occasional middle name or middle initial after the first name. Any help is appreciated

Clueless Newbie was forced to get into the manual and play around. I now have a file that reads for example
2016-196 John Smith but I want it to read Smith, John 2016-196 2016 being example yr and 196 being a file number (not in sequence) I am so close but can't figure out how to move or switch by characters because names are not a fixed character length and also a file number is not always going to be 3 digits. Could be 1,2, or 3. I feel like it has to do with a string but can't quite get it. Please help if you are a guru

I was totally uncomfortable with RegEdit and it seems that was the only way to get the job done. I watched a youtube video and figured it out.
