Hello,This Dell OptiPlex 7010 was to come with Windows 10 installed. It has Windows 8.A speed test and operating test was run on my computer for a position which I applied for with a companyfor a good paying job.My numbers were not in compliance by standards, and I did not get this position I was told because my operating system was outdated.I had to pay to get Windows 10 installed, and my location shows Columbus, OH not LA, CA.
