i bought my compaq mini 110c from craigslist and the os is windows 7 ultimate. it has 1gb ram and i'm thinking of upgrading it to 2gb ram. do you think i need to downgrade to home premium or professional of keep the Ultimate?Can i upgrade compaq mini 110c to windows ultimate?You can stay at Ultimate. I wouldn't downgrade because Ultimate has all the features of the other windows 7 versions (except enterprise which is only available to enterprises).Can i upgrade compaq mini 110c to windows ultimate?You should keep the ultimate version. It is much better than the other two by what you can do with hardware and software applications. If your computer runs ultimate fine then there isn't any reason to change.
