Synaptics may have just given Windows fans something to look forward to with its latest announcement, as it mentions a next-generation operating system from Microsoft with a focus on biometric security and Windows Hello.
The hint actually comes from a larger announcement from the biometric sensor company, who is joining forces with AMD to develop a "new industry benchmark in highly-secure biometric fingerprint authentication". The partnership aims to make use of Synaptics' FS7600 Match-in-Sensor, which is a fingerprint sensor technology that's completely isolated and contained within itself. This means that patterns are stored and matched separately from the rest of the system and the OS, thus adding a new layer of security to the authentication process.
According to the announcement, the technology will also be based on AMD's Ryzen Mobile platforms and a new operating system from Microsoft, which is referenced twice in the first paragraph:
Synaptics Incorporated (...) today announced a joint initiative centered on delivering a new industry benchmark in highly-secure biometric fingerprint authentication for enterprise/commercial and consumer notebook PCs based on next-generation AMD Ryzen™ Mobile platform and Microsoft’s next-generation operating system. The collaboration brings a new level of security for AMD-based laptops by leveraging Synaptics’ unique FS7600 Match-in-Sensor™ fingerprint sensor technology with powerful AMD Ryzen Mobile processors, and Microsoft’s forthcoming biometric security OS including Windows Hello.
While we haven't received any sort of official confirmation from Microsoft so far, we've previously heard of a new, lightweight and modern, version of Windows 10, known as Windows Core OS, which will be modular and adapt to all kinds of devices. Polaris is the codename of the variant which is expected to run on more traditional PCs, such as the notebooks mentioned in the announcement.
As to why Synaptics has gone ahead and teased an unannounced operating system from the Redmond giant, your guess is as good as ours, but Microsoft's partner conference, Inspire, is set to take place from July 15-18, so there could be some sort of connection to that event. If that's the case, we might not be that far from knowing more about Polaris and Windows Core OS.
