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 browsing and the search engine, 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 proletterbrowsers are not available in the Windows Store. However, it seems that even if Google were to release an app through the Windows Store, users of the new operating system would 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 app must not compromise user safety or its security or functionality devices, of the system or related systems. Web browser applications must use the appropriate HTML and JavaScript engines provided by the Windows platform,” the Windows Store guidelines 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 cites security reasons for these restrictions, with a company spokesman explaining that Edge operates a sandbox environment and thus protects users from potential malware and exploits. Other browsers should do the exact same thing (have a sandbox environment), so they should be developed from scratch using Microsoft technology.
