Just a general warning about updating or clean installing Windows 10 Anniversary Edition Update your tablet (or laptop or pc).
Windows 10 anniversary update can have problems updating if you have a second hard drive attached or a sd card inserted in the card reader slot.
In some cases after a clean install or update you can no longer read the sd card or attached second drive (this happened to my sd card on my Jumper Ezpad mini 3).
In some cases, if you have currently installed programs to the sd card (or another drive other than the c:drive) and/or have redirected your personal folders (eg, my documents) to a sd card (or another drive other the c: drive) to save space then the update can fail (this happened to a family member’s PC)
So I recommend that prior to the installing the Anniversary update on your tablet:
1. Make a back up (don’t rely on system restore as I found out the hard way) of important data (and any device drivers).
2. Make sure you don’t have any programs installed or have any personal folders redirected to any other drive than the c: drive.
3. Remove/disconnect any other drives, sd cards etc other than the c: drive.
