Same thing happens to me.
Code: Select all
[10.192.168.147]: PS C:\Users\Administrator\Documents> shutdown /s /t 0
System will shutdown in 0 seconds...
[10.192.168.147]: PS C:\Users\Administrator\Documents>
Boots right back up. I'm sure they'll fix it in the next release or so. In the mean time I wouldn't really worry that much about corrupting anything. If anything does end up breaking you can just re-image the SD card. Not very many settings/customizations to lose compared to a traditional PC.
