Last year I bought a new Inspiron 3668 with SupportAssist on it, which works fine, to replace my old HP with Windows 10 on it which blew up beyond recovery. I don't have a lot of Apps installed on it and just will use it occasionally, particularly when traveling.
I activated it with Microsoft with the Windows Refurbished activation number from the sticker on it. Earlier this year I purchased a Latitude E6410 from an authorized Windows refurbisher.
