Microsoft declares that the newest version of Windows 10, the Fall Creator’s Update, is the most secure version of the operating system yet released.
The Security measures add protection against ransomware mentioned by John Cable, Microsoft’s director of program management, Windows servicing, and delivery. This is being controlled by a new version of the company’s famed Windows Defender called Windows Exploit Guard which is designed to stop remote code execution.
Windows Defender Antivirus has new safeguards added to protect against most commonly used variants like Locky, Cerber, and Spora along with WannaCry and Petya. The last two types of malware targeted Microsoft products through the EternalBlue exploit.
The Update is being rolled out in phases with most Windows users having it download in the background and then be prompted to install the software. Others may have manually updated their machine.
As Microsoft explains that “This feature protects your files from tampering, in real-time, by locking folders so that ransomware and other unauthorized apps can’t access them. It’s like putting your crown jewels in a safe whose key only you hold.”
By default, common folders where user data is stored like the (documents, pictures, and Video folders) are protected by the controlled folders you want to be defended against malware.
Note that you will need to upgrade to the Creators Update to get this feature, and not everyone will have been offered it yet.
Microsoft added, “[This] and other security technologies [introduced in the Fall Creators Update] protect against persistent ransomware campaigns like Cerber, Locky, and Spora, as well as global outbreaks like WannaCry, and Petya”.
Microsoft has also mentioned that it had tested the update with more Windows 10 devices in advance this time around, which is theoretically mean a smoother(and perhaps) rollout.
That said, “we have already seen some issues, although that’s not uncommon with an upgrade of this size and scope (if you’ve encountered any gremlins, we’ve got another guide on how to fix common problems with the Fall Creators Update)”.
The download size of the update is also smaller to the tune of 25%, Microsoft notes, because of the use of ‘differential downloads’ (at least if you grab the upgrade via Windows Update).
