I've ordered a few of these, great budget machines for low volume use. These shipped with Windows 10 Home, but advertised with Windows 10 Pro, which I need to join to a domain. The seller contacted me and provided me with Windows 10 Pro license keys which got me going, but I'd make sure first thing to check to make sure you got the correct Windows version before you start to configure these and install software... The Windows 10 Pro keys they gave me required me to reinstall from scratch.
