This was purchased to replace my Windows XP machine which had failed. I had considered repairing my old PC and buying a copy of Windows 8 but the purchase of the Dell was much better value for money. It is a high quality robust computer with Windows 8 installed and a genuine Microsoft Windows 8 DVD. Be aware that the DVD drive is not a writer but it was very easy to swap with the DVD writer out of my old PC. I inadvertently damaged the memory by adding the incompatible memory from my old PC. I returned the Dell to MicroDream who diagnosed, repaired and returned the machine with no charge within 2 working days. You can ask MicroDream to add more memory before delivery for a very reasonable cost.
