Indeed this is expected to be the solution here too. It seems that the Windows 10 "Anniversary Update" (1607) behaves as an OS upgrade (always requiring to uninstall and reinstall Paragon file system drivers) and not as an ordinary OS update (not requiring any action).
If the usual uninstalling procedure (via Windows Control Panel) is no longer possible after the Windows upgrade, please contact the Paragon support team to obtain a specialized uninstall tool for HFS+ for Windows.
