Computer looked to be in good physical condition.  During initial set-up, Windows Defender warned me of  virus on computer rated "Severe".  There were over 30 incidences of the virus (which replicates itself on different files).  I didn't finish set-up and returned the computer the following morning.  Very disappointed. I don't know if it worked otherwise. Unlikely to ever use supplier, and now quite suspicious of "Certified Microsoft Refurbisher"
