The trailing comma is necessary. It ensures that any settings added by another piece of software or GPO are delimited as necessary. Most errors related to this occur because the installation routines are not configured to place the comma at the end of the string; the key is corrupted because it is not read properly unless it is delimited correctly.


So comma acts as a delimiter.If delimiter is not present key will not be read properly.

So comma will be always used to separate values in all files.

To understand better please see this tutorial.

Well, I'm not sure in this specific instance, but a comma usually means a backup file in my experience.
