I don't use Windows but this is how it works on a Mac. You have to point Windows Explorer to the Kobo, not your computer file system.

- Plug the Kobo into your computer via USB.
- When the Kobo pops up the message "Computer Detected" click "Connect"
- Wait a minute, and then find "KOBOeReader" in the devices list or network list, or whatever it is called in Windows. It's the same place a thumbdrive (flash drive) would show up when plugged in.
- Click on "KOBOeReader".
- Make sure "Show Invisible Files" is on (however Windows labels it).
- Navigate to the directory .kobo (note the leading dot before kobo)
- That should show you a subdirectory that includes Kobo.
- Click on Kobo. Thats where you will find the file "Kobo eReader.conf".
- Edit the configuration file using a simple text editor, not MS Word or any other word processor type program. It must be a pure text editor with no formatting, and save files with Linux line endings.

Edit to add: make sure you eject the Kobo from Windows Explorer before unplugging the USB cable. Wait for the Kobo display to change to confirm it has been ejected.

Edit again: Sorry, ignore the part about editing "Kobo eReader.conf" - that was for a different reason. Follow the instructions the others have given.
