The formatting of the MicroSDXC shouldn't be the problem as it's only for storage, any download of Win10 should go onto the C: drive but I was given a choice of the D: drive during the install for storing temporary files, just about 16GB worth. The MicroSDXC drive could be FAT32 but Windows will balk at that do to it's own limitations of FAT32. I once used a 64GB USB Thumb drive for the suggested recovery drive but Win10 would only format 32GB of it as FAT32 and left the rest of the drive unusable in Disk Management, had to use a different method away from Windows to recover the whole capacity.
Make sure your tablet is plugged in. If WIndows thinks your battery is low it may abort the installation.
I tried as you suggested formatting sdxc card to exfat and upgrading. That also failed. Further I removed that card and retried upgrading. That also failed to upgrade. Every time goes to upgrade stage of 87% or 91% and then gives a message that reboot will happen. Then it reboots to windows8.1.
I would check and make sure you do not have any missing or corrupt system files. To do that open a command prompt as administrator and type this command "sfc /scannow" without the quotes, then press enter. Hopefully everything checks out ok, but if not, replace the missing or corrupt files.
