What a bunch of unhelpful and ignorant replies!
It is always a pleasure to see a competent and knowledgeable answer. Especially if it is expressed as politely and carried by good manners.
I can not say if this also applies to the Wouxon radios. For the Baofeng you don't need a Win 8 driver, quite the contrary you would have to use an older one. Prolific 220.127.116.11 is the recommended driver from Baofeng and is now included on their software CD. It may be similar for the Wouxon at least if you'd use the Chirp software.
This is only incidental to the USB to serial chip used in these interface cables. It has nothing to do with the programming software since the software, whether manufacturer supplied or Chirp, only thinks it is talking to a serial COM port. Any serial to USB cable would work if it has the correct electrical connections to the Wouxon or Baofeng radios. Unfortunately, the commonly available cables for these radios use the Prolific or Prolific clone chip, and the driver for this chip is not yet updated for Windows 8.
You could make you own cable out of USB to serial converter that is known to work on Windows 8 (this is what I have done) and it will then work with any of the programming software out there. I use Chirp. If you are not willing to do this, you will have to wait until the available programming cables have their drivers updated. It is a simple fix to the driver signing requirements, but the manufacturers don't seem to be in any hurry to update the drivers.
Here's a schematic of a simple homemade programming cable for use with a serial port. http://www.kh-gps.de/888_10.jpg
If your computer with Windows 8 already (by some miracle) has a serial port, you are ready to go. Otherwise, get a USB to serial converter cable that is known to work with Windows 8 and connect the above homemade cable to it. Select the COM port in the programming software and go to town programming your Wouxon or Baofeng on Windows 8.
