Built-in disc burning software in Windows 10

If you single click an ISO file using File Explorer "Disk Image Tools/Manage" shows up in the ribbon (much like MS office 2007 and later). If you click on "Manage" two options should appear below. Selecting "Burn" will give you the tool that you are looking for.

You should also be able to right click the file and select "Burn disc image" in the menu.

If you have a program like VCD associated with ISO files the options above will not show up.

Supplementary trick: to restore the tab showing up in the ribbon, you do not need to un-install anything: just reassociate .ISO with Explorer (right-click on any .ISO, Open with... submenu, select File Explorer and check the Always use... box; you can do the same thing with the Associate control panel).

For others, who don't have the "Manage" tab in Explorer, use "Open With" -> "Other application" -> select "c:\windows\system32\isoburn.exe"
