I bought three of these computers and two of them were delivered without an operating system. That is the message you get, there isn't a product key. The little paper you get on the top of the laptop says that if you have issues to contact Acer directly before calling amazon but i wouldn't waste your time. They told me that i could wait a week so they can verify my purchase although i had given them the serial number off of the laptop or i could call amazon and get a replacement. After getting off of the phone with Acer I called amazon, that wasn't that much better. I did get a replacement however I was charged another $377 or something for a new laptop until i returned the other one. the third laptop was purchased on her account, this is where the second laptop without an operating system came from. Before my wife's laptop arrived it wasn't shipped out until about 4 days after purchasing it. she called before they shipped it out and asked why she hadn't gotten an email about it shipping and they said they had a lot of orders which is believable. about a day or two later she got an email stating it shipped but we never received it so about a week went by and she called again. they told her that it had gotten lost in the mail and they were shipping a new one. Five days later a here it is, a laptop without an operating system. So of course the wife calls for the third time and they said that they will arrange that UPS comes out and picks up the package BUT they can not ship her a new one because they are coming from a different vendor now? I'm assuming its because when we purchased them they were $364 and now they are $385 so amazon doesn't want to eat the extra cost. This is the third order amazon has messed up for us in 2 months so we are just going to start paying a little extra at local businesses.As for the laptop, I think it's a good laptop for anyone that needs a better than budget laptop for a budget price. If you leave all the programs on it like microsoft edge instead of google chrome it runs great. it can multi function well. its a little sluggish if you are used to fast computers at work or something then you use this for home browsing, you will definitely notice the difference. I would tell someone that this is a good product if you don't run into the same issues i did. It's just not worth my time to have to call them and ship items back since the 3rd laptop is the second one I am sending back and not even getting a replacement.
