Hi David, check out Brian’s post below. Search for a file named “DUALOSSWITCHER.EXE” on your hard drive and it should allow you to switch back to Android when you run it.

Wow…that is unfortunate regarding the Android apps. I wish I had known that before I purchased this tablet actually…would have probably steered me away from this product entirely. I mainly bought this tablet as an e-reader for comics since I am switching to digital media for most of my subscriptions. Makes it hard when the comics are coded into the actual reader app so I cant even save them separately on the flash drive. Being mainly a Windows user, the sexiness of the dual OS really wowed me since I don’t have access to the Android marketplace with any of my other devices.Thanks for the info on this…looks like I just purchased a dedicated Hearthstone tablet. I guess I will keep looking for a cheap e-reader that will suite my apparently ridiculous storage requirements 🙂

In Windows 8.1 mode it was simply, you update your default drive locations in Windows OS to point to your SD Card, you can install almost anything there except Windows STore installs, so need to install apps traditional desktop applications, not through Microsoft Store which can only use C Drive. For Android, the option is in the individual app when you go to the application, some give you the option to “move to external device” or SD Card, very few Android apps I find actually support this, and no games however.

Thanks for the information, Brian!

I was able to to get Win 10 upgraded and have the switcher in place and the touch tap working correctly. (1) for the OS switcher, search and locate the DUALOSSWITCHER.EXE file and pin it to your task bar. When you doubleclick, it should work just like it used to. I had located it before doing the upgrade and had copied it to a SD card I had put in the card slot, just to make it easy to find. (2) For the tapping problem, follow instructions here: http://techtablets.com/forum/topic/how-to-update-to-windows-10-on-chuwi-vi8/ .

In particular, follow step 5 to download this file: http://www.mediafire.com/download/jejnn0bnoonv0aw/Vi8_Win10_10240_X86_Drivers_Update_Sorted_By_Junnie_V150806.rar.

And then follow step 14 to do this: The touch driver installed by Win 10 is wrong. So first thing you do, after logging in, is using your mouse, open explorer and navigate to the DriversTouch_PG folder on your USB, right click on SileadTouch.inf and select Install. Now your touch will work properly.

Thanks for the information, Ron! It looks like Windows 10 is not worth the hassle on this tablet. I, too, have been happy with Windows 8.1 on this tablet (I like Windows 8.1 a lot better on a tablet than I do on a desktop computer).

Yes, it will upgrade with the micro sd card. I think I used a 32gig, but I think a 16g will do. It just needs a little extra storage. I had no problems with that part. It worked beautifully, in a timely manner.
The problem I had once upgraded, the touch screen was all messed up. It was about an inch off from where I was tapping, meaning I had to tap/hold about an inch above where I wanted to type/login in and with the built in keyboard. Unless you have a Bluetooth keyboard and mouse. Whether or not it was my fault or something that could have been easily resolved, I couldn’t use it and switch back to W8.1.
Also, I couldn’t figure out how to switch from W10 (once upgraded) to Android. There is no icon to switch OS systems from W10 to Android, mind you I didn’t hunt for it. I just wanted it usable again.
To me, Windows 8.1 is a better for this tablet and because there is very limited information on this. It works great with w8.1 and have no complains as of yet.

I have not. I’ve inserted a Micro SD card, and while Windows detects it and I can browse it in Explorer, the Windows 10 installer does not allow me to select it. I’ll need to keep looking at this.
