Playlist issue after Windows 10 Creators update

Been researching on the Boards and I see instructions for installing a firmware update, but not for uninstalling and reinstalling the firmware version I already have.

If I just follow the instructions for installing the firmware - in MTP mode in my case - so drag and drop the extracted clpzV010121.bin file to the root of the Internal Memory folder, will that simply replace the existing firmware, or do I need to perform an ‘uninstall’ first?

If so, any advice on how to do that would be appreciated.

Thanks for the advice and suggestions to date.
