I'm very very pleased with this refurb computer.  It's fast with Core 2 Duo and it doesn't cost much more than a Win7 Pro license (disk).  I'm not a gamer pushing the FPS limits but for any business application it has more than enough CPU power and works great.  I'm not interested in upgrading to Win10 so I don't have personal experience with Win10 hardware compatibility of this model.I bought mine on Amazon and the seller was "Metro Business Systems" - they gave me outstanding email support.
