I picked up a couple WinBook TW700’s from MicroCenter back around Christmas time and after seeing some good stability results running Windows 10 preview on my Surface Pro 3 I thought the tablet would be a good device for the OS, too. I decided to do a clean install completely formatting the “hard” disk so I could get back the recovery partition space. The install is pretty much like on any other computer, but there are some driver issues that you need to be aware of so I wanted to post the steps here. This was with the current technical preview release build 10041 so any future builds may be slightly different and, hopefully, an improved experience with driver updates.
First of all, if you ever want the option to rollback to your Windows 8.1 install, you’ll need to create a recovery USB drive. Plenty of info on how to do that on the Internets so I won’t try to cover it here. For what it’s worth, I didn’t bother. 😉 Once you’re comfortable on that front, hit up the Windows Insider site to download the latest Windows 10 build. You’ll need a USB stick at least 4 GB to use for the tablet install so procure one if you don’t already have one. Format the USB to FAT32, mount the Windows 10 ISO on your computer and copy all of the contents of the ISO to your empty USB stick.
Now head over to your tablet. Since drivers aren’t available for many of the devices on the 700, the easiest way I found to get them updated post-Win 10 install is to copy the existing. Navigate to c:windowsSystem32DriverStoreFileRepository and copy the entire FileRepository folder to another USB stick and keep it handy. Now get a USB hub plugged into your tablet so you can have at least three devices plugged in at once. You’ll need to attach a USB keyboard, USB mouse and your USB drive with the Windows 10 installation files. Once that’s all hooked up, restart the tablet. When it’s starting up, hit F12 to get into the boot menu so you can choose to boot from the USB. From here on out it’s a basic Windows install so have fun with that and come back when complete, formatting your drives during the process if you so wish.
Now you should have a nice clean Windows 10 install and noticed that pretty much nothing works, except the USB mouse and keyboard :). Remove the Windows 10 USB and plug in the USB with the drivers. Launch Device Manager and you’ll see many yellow exclamation points. For each one you see, right click to update the driver and choose the option to search a local folder for drivers and select your USB. This will take some time and new ones will pop up after updating others, so just be patient and keep going until all the exclamation points are gone. Once Device Manager is clean, restart the tablet. After it comes back up, you’re up and running and all devices, including the touch screen, should be working. Lastly, run Windows Update to grab any updates there and restart if prompted. Unplug the USB hub and have fun tabletting on Windows 10!
