Install WinUSB using the [Zadig](http://zadig.akeo.ie/) utility, by selecting Options->List All Devices, select "STM32 BOOTLOADER" and click Install Driver.
Download [dfu-util](http://dfu-util.sourceforge.net/) for Windows (version 0.9 at the time of writing) and unzip.
Execute:
```

To install the firmware execute:
```
dfu-util --alt 0 -D pybv10-2014-05-19-v1.0.1-24-g5cdff5f.dfu
```
Which should show progress bars for the firmware download to the pyboard and complete with:
```

```
After the the program has finished, disconnect the pyboard from USB and remove the jumper between the DFU and the 3.3v ports.
