Method 2B - Disable KFX support in Kindle for PC/Mac The batch file must always be used to launch Kindle for PC before downloading books. If Kindle for PC is started without using KFX_begone4 it will revert to allowing KFX. If that happens remove the book and download it again. If a book downloads while the batch file is in progress it may be delivered in KFX format. After that any books downloaded using Kindle for PC will be in the older Kindle formats. The batch file may take several seconds to terminate. (Thanks to DNSB.) When launched this batch file will start Kindle for PC and then apply a registry change to disable KFX format.
