Good performance I am happy with the Purchase, I contacted HP and they told me that if i send them the Amazon invoice they will be updating the warranty to 2 years from the date of Purchase. It came with Windows Home but I have upgraded to Windows Professional. I will be using it for work and not gaming. It has both the ram slots in use hope one of the slot was empty then i would be able to upgrade easily. so far no issues, looks good and is fast.
