Feature request from blizzardengle, posted on GitHub Nov 22, 2016
The dashboard on Magento 2.0+ chooses to display Guest in place of the customers actual name on the Last Orders grid when the customer checkouts without being logged-in.
The Last Orders grid should show who actually placed the order (Billing Name) instead of guest regardless of the fact that they were logged in or not.
Look at the OP's screenshot. Look at the Last Orders grid on the left and it will say Guest and not the customers actual name
This issue was raised before but got closed because of formatting and lack of updates, see: #6995

@blizzardengle thank you for cooperation!
Current state corresponds our internal requirements to dashboard, so we don't treat this issue as a bug. Your request was added to a story for dashboard improvement(MAGETWO-11358), but it's not guaranteed to be implemented this way. Please submit this improvement to the new Magento 2 Feature Requests and Improvements forum (see details here).
Agreed. This would make way more sense to show the billing first / last name than "Guest"
