@your_girl_ziy In theory, you could "upgrade" to the regular version of Windows 10 and download Origin. However, computers that come with Windows 10 S mode installed are almost universally under the minimum requirements to run Sims 4. Plus, among other things, they generally have very small hard drives, so there might not even be enough room to install the game, let alone play it.
If you post your budget and country, I can list some laptops that would run Sims 4 and let you know more or less how well they would handle the game. But they're probably going to be more expensive than a typical HP Stream.
