I like MiniTool Partition Wizard:

Delete the partition containing the Windows 10 that you no longer want to keep. Then expand one or both of the partitions next to it to fill the empty space. Or you can create a new drive letter in the empty space if you want. Be sure to click the apply button, nothing actually changes on the hard disk until you click apply.

If you still have an additional Windows 10 showing up on the boot menu that is no longer there you can run:

msconfig

Select the boot tab and you can delete the extra entry there.

I, and most long time members here, prefer to use Macrium Reflect Free for our backup images:
