I bought it then realized how old it was. About 9 years old, but my laptop was older. It works great. Starts up quickly. It will slow down severely if you save stuff to the C drive so you need to save items to the D drive. Then the pages don't load slowly. It is running on Windows 10. I didn't realize Windows 11 is out but will be harder to download to this desktop. I read it is possible. Overall, I am very pleased with this purchase. It has made working from home a whole lot easier, and also just surfing the internet is way easier, then using a smaller screen from my previous laptop. I had to purchase a monitor - it works great with this desktop. Desktop is very quiet.
