the only issue was that a temporary windows 8.1 OS was installed when no OS was ordered, I understand they are making a effort to make it easier to users when they turn on their new pc right out of the box. but windows 8 itself makes it difficult for people who prefer to install windows 7 or XP themselves since the hard drive format and security are set up differently. windows 8 makes every effort to prevent users to "downgrade" their OS. so you have to get on with the tech support to walk you through resetting your system's BIOS settings in order to be able to install anything other than windows 8 in your computer.
The computer is excellent.
