Whats the market for Windows 10 S? As in, why would anyone offer the locked-down version instead of the full OS? What cases exist where this is the only thing allowed?
Windows 10 S market would be mostly Elementary and High Schools, and non-creative content workplaces like offices, libraries, data entry and banks which may not want their PC users to install third-party non-approved programs off the internet, or from a USB drive which may contain viruses, spyware, and malware, or waste the users' time when they should be working.
But, creative content workplaces like web designers, 3D animators, and video editor departments will most likely find Windows 10 S overly restrictive because the software which they need to use may not be in the Windows App Store, so they can't run it. Web designers usually need to use multiple web browsers like Firefox, and Chrome to test out their web design, or to see if a video or 3D web app they publish on their website works well in Chrome and Firefox.
Some less tech savvy parents may also feel more comfortable letting their younger kids use a Windows 10 S computer because their young kids can't install games like first person shooters, and fighting games from websites.
Windows 10 S also has features like Bitlocker, Windows Store for Business, Mobile Device Management (MDM), etc which are also found in Windows 10 Pro, but not found in cheaper versions of Windows 10 like Windows 10 Home.
Windows 10 S is also more lightweight because it is designed to work well on
cheaper $200-300 laptops which typically have an Intel Celeron N3450 processor, 4GB of RAM, and 64GB of flash memory storage. I think 10 S is more lightweight because Windows 10 S is mainly designed to run Windows Store Apps, MS Office, and other Windows 10 S approved apps which don't use a lot of system resources in most cases.
Windows 10 S is a business operating system, and have many features which Home users would rarely use. Windows 10 S license is free compared to Windows 10 Pro and Home which are not free. If the Windows 10 S computer will be used for mainly MS Office, other Approved Windows 10 S Programs like Microsoft Edge and Visual Studios, and Windows Store Apps companies and schools can save money by using Windows 10 S computers instead of 10 Pro computers which will cost more because Windows 10 Pro license is free, and need faster hard ware like a faster CPU and more RAM to run smoothly.
I think not many regular electronic stores will sell many Windows 10 S computers since most regular users will most likely buy a Windows 10 Home laptop or desktop computer which they can affordably buy for $300-400 and up, or a $100 Windows 10 Home tablet which they can turn into a laptop by plugging in a USB keyboard and mouse. Home users also want to continue to use their software which they bought from a non-Windows Store software store or downloaded for free from a download website like download.com and SourceForge, and play their many PC games which they bought from Steam, Gog, Humble Bundle, and other online game software stores.
