Will Windows 10 S be Impervious to Ransomware?

Will Windows 10 S be Impervious to Ransomware?

Microsoft is making some bold claims for their upcoming variant of the Windows 10 operating system, that it is safe from all currently known variants of ransomware. This is largely due to the architecture that limits what software can be launched and how applications are isolated. But will it be enough to keep the next generation of ransomware at bay?  

Microsoft offered evidence by saying that no Windows 10 customer was affected by the notorious WannaCry ransomware that ran rampant back in May and took down a chunk of the European healthcare system.  Windows 10 S is a specifically streamlined configuration for maximizing security and performance, designed for students and teachers. It offers benefits, but comes with some configuration and operating limitations.   

It exclusively leverages the Windows Store for applications and by default the Microsoft Edge browser for more control. Additionally, Windows Defender, Device Guard, and other security features will be included. Only software available from the official Windows Store can run. This limitation ensures that only vetted software is operating on the system, but can greatly inhibit some users as all command-line apps, shells, and consoles are not permitted.  

The S variant is part of the Windows 10 suite and is only available as a pre-load on laptops and tablets. For those who find the application restrictions too limiting, they will be able to upgrade to Windows 10 Pro.

Microsoft has learned much over the past two decades, invested in tremendous security capabilities, and has a lot at stake. I hope they can deliver on their bold claims as ransomware has become a tremendous problem that will not go away easily. There is just too much money for attackers to make. I know for certain, cyber threats will put Windows 10 S to the test and only time will tell if the Microsoft battle plan can keep the malware at bay.

So it's not really a fix for windows at all, it's a feature reduced version that may be more secure. What they need to do is add a feature that has default deny on running all applications until they are verified as ok or completely block if they are bad, than any new variant will not work as it would be "unknown"

Can't see this concept of huge white listed device/system to work.. 1. Users want to be anonymous 2. They're seeking freedom in applications they use. 3. New malware have ability to install with minimal user interaction ie. mouse hovering...

Wonder if Microsoft will ever support ARM Processors. Love to see a Qualcomm based Windows tablet with 625+ 8c 2.0GHz+ 4gb+ ram.

Streamlining downloaded apps to the windows store isn't a terrible idea to ensure security. At the same time, user flexibility might be an issue.
