Boot a Microsoft Surface directly in to User Mode?

We 开发者_C百科are planning to have an automated nightly restart of the Surface. Is it possible to boot it directly into user mode? I haven't been able to find anywhere to configure the default boot mode.

If not, can it boot into admin mode but then execute a command on startup to kick it into user mode?

After you put it in user mode, reboots should go into user mode automatically
