This refurbished desktop runs great! It was purchased to replace my old desktop (similar model) which was fried by a lightening strike.  I just need something to run a few business applications and general simple household software.  I especially appreciate the fact that it comes simply with Windows 7 Pro and Explorer - no junk added on.  I was easily able to load all of my software that I need for daily use, and set it up just like my old one. I am planning on updating with Windows 10, but haven't done so,as of this review. Hopefully that will run just as smoothly.  I will be purchasing another from this seller for my son, who is a student.
