I purchased this from Best Buy and used it for a few business trips, and then stored it away. It comes with a cover, Microsoft OEM stylus pen, and the keyboard.
It has never been used without the cover. Everything works great and I have reset the machine so whoever purchases it will be able to set it up how your prefer.
The only thing I did notice was some very light stains (coffee?) on the keyboard. It is hard to notice and even harder to get a picture of it and obviously doesn't hinder the function.
**This model can be upgraded to Windows 11 as per this Microsoft Support notice**
