Microsoft's latest Windows 10 Fall Creators Update is now officially available for all compatible devices, the company has announced. "I'm happy to announce the Fall Creators Update (version 1709) is fully available for all compatible devices running Windows 10 worldwide. Full availability is the final phase of our rollout process," John Cable, Director of Programme Management, Windows Servicing and Delivery, wrote in a blog post late on Thursday. Microsoft started rolling out the Windows 10 Fall Creators Update on October 17 last year and the company claims that it is the fastest Windows 10 release to reach 100 million devices. The Windows 10 Fall Creators Update is also ready to be deployed by IT administrators in several organisations worldwide. "We're pleased to announce that the Fall Creators Update was the fastest Windows 10 release to reach 100mn devices, all while achieving higher customer satisfaction ratings compared to prior updates," Cable added. Highlighting the need to protect devices and the information in them, Microsoft took note of the recent "Meltdown" and "Spectre" CPU vulnerabilities. The new update brings security updates to curb these vulnerabilities, however, Microsoft recommends that the users should also install firmware updates from their respective PC manufacturer to ensure complete safety. "We build the latest security technology deep into the Windows OS to provide defence-in-depth features that prevent evolving malware and other vulnerabilities from impacting your device," Cable noted. The company spends over $1 billion every year on cyber safety and security-related research and development. While announcing the update, Terry Myerson, Microsoft's Executive Vice President for Windows and Devices, had said that the free update will also include a new photo app and many tweaks to the overall design and usability of Windows 10.
