Out of the box, it seemed to work fine. After I updated windows, I tried to install our ERP software. After it didn't work the first time, I tried to uninstall it. That failed. I tried to install .net update. That failed. Looking at the event log, it seemed like anything to do with the the windows installer failed. Once I realized that this thing didn't come with a Win key or documentation, I decided to send it back. I'm going to try an Intel NUC next.
