I have a 8" Toshiba encore 2GB / 32GB tablet with 128GB MicroSD with 17.4GB free on C: and over 80GB free on MicroSD. Despite all this space I can't update Windows 10 version 10240 to 14393. When I hit update now it says CPU, Memory and Disk Space OK then I click next and it says not enough disk space 
I've tried running disk cleanup but no joy!
I really don't want to do a wipe and re-install if I can help it.
Any ideas?
