The next major Windows 10 update is scheduled for a Spring 2019 release and some clues in a recently released Windows 10 19H1 SDK suggest this version will add support for WiFi WPA3. This new security standard enables easier linking with smart devices that do not have a screen, protection against brute force attacks, and forward secrecy, meaning attackers who retrieve a WiFi network's password will not be able to decrypt traffic recorded before discovery of the key.
WPA3 is the enterprise version, while WPA3 SAE is the consumer version with Simultaneous Authentication of Equals (SAE) , replacing Pre-shared Key (PSK) in WPA2-Personal.
WPA3 is interoperable with WPA2, so the support is likely only needed for sites which takes security very seriously. Those facilities will likely have to wait till early 2019 for the feature to become available to all Windows 10 users.
