A:Answer If it doesn't SAY Pro, it's a version of Home, either S Mode or not. Professional version of Windows is only on computers aimed at the professional (=enterprise=business) and some gaming machines, since the chief difference is that Pro provides increased security and privacy. If you want to upgrade, it is a simple and reasonably quick procedure, usually at a price point of $100, although I have occasionally seen sales (usually coupled with the purchase of another product, such as Windows 365) as low as $25.
