Removing TempDB data files from SQL Server

I had a situation where a SQL Server 2016 install did not install correctly. The install completed but when I tried to move the tempdb datafiles over to a separate LUN, it created new files, leaving the old ones in place and active, so I ended up with 16 active tempdb datafiles. Here is how I removed the old 8 datafiles still on the D: drive
