This is a very good computer, I ordered it for a customer. It works well and it's very fast. The original computer listed windows 10 pro with a cd/DVD Drive. The machine I received was a newer version with Windows 11 pro and no cd/DVD. I gave my customer an external cd/DVD Drive and he was satisfied with it. I lost a little money on the deal because I had to supply the external drive. However, my customer really likes the new computer.
