The E6400 was an awesome laptop that I still own today, other than the dead battery the computer runs amazing still. You put a SSD in one of these laptops and you will love the performance. Mine originally came with Windows Vista, I later did upgrade to Windows 7. No drivers were released for Windows 10 but it does run Windows 10 most drivers should be builtin to Windows 10.
