how to rename music files in Windows 10?

Right click only helps in changing Name of File column.  I used to be able to click on file, and on the bottom I was able to modify other columns...ie, Contributing Artists.  The only solution I found so far, was through renaming file in Media Player.  The modified Contributing Artists column changed in File Explorer...however, now I have one track that keeps the VARIOUS ARTISTS original tag name and can't seem to change that last remaining track.

In addition, renaming in Media Player from VA to Artists' name, creates a folder for that newly added Contributing Artist in the Files Explorer > Music folder.  

Windows 10 has been nothing but headaches...any way to simplify the renaming of music files?

I just noticed that if the file is in currently playing (or in "Now playing" list) updating the meta data for the file is not possible. Close WMP and re-open it directly (wmplayer.exe) and see if you change the tag in the Library view. Alternately, you may try a 3rd party utility like MP3Tag.
