Google Chrome and Windows 10 S: The new Windows 10 S operating system revealed by Microsoft is limited to running apps only from the Windows Store, and the company confirmed that users will not be able to change the default program tourand the machine searchs, which means it will only work with Edge and Bing.
This will of course be a big problem for friends of other browsers (Firefox, Chrome etc) because the other browsers are not available in the Windows Store. Nevertheless, it seems that even if Google released an application through the Windows Store, users of the new operating system will still not be able to use it. 
A publication in ZDNet reports the special requirements for browser-only Windows Store applications that a version of Google Chrome could not comply with.
“Your application must not compromise user safety or the security or functionality of the device, system or related systems. Web browser applications must use the appropriate HTML and JavaScript engines provided by the platform of Windows," the Windows Store instructions state.
Microsoft offers developers a set of tools codenamed Project Islandwood that enable the transfer of Win32 software to UWP (Universal Windows Platform) applications.
In theory, if Google wanted to release the desktop version of Chrome in the Windows Store, it would have to use Project Islandwood's tools, but according to the requirements above, the search company would need to develop the browser from scratch using rendering engine and Microsoft's JavaScript interpreters.
Microsoft lists the security reasons for these restrictions, with aface of the company to explain that Edge operates in a sandbox environment and thus protects users from potential malware and exploits. Other browsers will have to do exactly the same (have a sandbox environment), and for that they will have to be developed from scratch using Microsoft technology.
