A:AnswerChrome books use Chrome OS. Completely different from windows 10. It utilizes apps like a moblie phone would to do things. I would hight recommend youtube comparison videos before you purchase it. It took me a bit of time to get use to
A:AnswerI would guess no. Chromebooks are not known for being upgradable and the RAM is soldered onto the mobo. I believe the storage on this device is NVME so IT might be upgradable, but I highly doubt the RAM will be.
