1. Type Control Panel in search menu and open it
2. Choose Clock and Region settings
3. Choose Change date, time, or format settings
4.In Format tab click on Additional settings (Win10).
5. Type a new separator in the List separator box.
6. Click OK twice.

I some countries it will be necessary to put "." as decimal symbol and "," as Digit grouping symbol to make the list separator work properly.
