Microsoft is releasing a new version of Windows called Windows 10 S.
If you want to be able to run CNCSimulator and thousands of other programs (like all Adobe products) do not buy a computer with this operating system. It is a limited version of Windows that just allow you to run software from the Microsoft app store. A computer with Windows 10 S is more like a Chromebook than a real computer. Microsoft is trying to force everyone to use their app store so they can take a share from every sale just like Apple do. It is bad news for the consumers as well as for all independent software creators.
Please have a look at this video by Jerry. He has been an employee at Microsoft for 15 years so he knows what he is talking about.
