Hi there,
We have a similar issue we have a 1010b Windows 10 tablet and the user has forgotten the local windows password, not a live account. We have tried to get access to the command prompt, and reset but both require you to log on with an admin account, so we then turned to try to boot from USB optical and USB memory stick, both of which failed when the tablet said that was not a boot option, and we could only choose windows boot manager or EFI shell. Any ideas ??
I have contacted Linx and they have said all they can do is get a USB flash drive (probably at a cost) out to us in around two weeks after I email in!!!!
