I have successfully rooted my MSI Windpad Enjoy 10. I will write up a HOWTO for all you Windpad 7" users soon, however all the Enjoy 10 users can benefit from my rooted firmware. Note: all 3rd party apps (except for google apps) are removed except the keyboard (as I found this to be easier to use than the stock android keyboard). English languages only.
Update.img file here:
You will need 7zip to extract this file. Simply copy the update.img to your msi windpad and when you disconnect your device from your computer it will start the firmware update.
NO SPECIAL DRIVER NEEDED.
