Refurbished Laptop arrived is clean, functional (everything works) and has the MS Windows 10 Pro sticker on bottom, it means the seller is Microsoft Certified Retailer. This is the second one I have ordered from this merchant.This old Dell laptop does everything as the brand new ones but for a lot less money. it has features like Ethernet port for direct connection.It does not run Windows 11, I do have Windows 11 on my desktop and I do not like the User Interface and can't tell if it runs faster than Win 10, most important is Windows Pro edition has essential features that are not in Windows Home editons.
