The features describe this as having the Windows10 OS installed. But mine has windows 11 right out of the box, and i am unable to roll it back to 10.Windows 11 is an atrocious, dangerous pile of buggy garbage, and it has destroyed my previous laptop that this is replacing. I am very disgusted by this, as this laptop has already crashed within 30 minutes of use out of box.Plus. I can not get through to amazon customer service, only that useless, meaningless AI.Be very careful with this purchase.
