If you have the regular 10240 build of Windows 10 that launched on July 29, you might be getting an automatic download soon. Microsoft has released a new cumulative update for Windows 10 users, with the support name KB3097617.
At the moment, there's no word on what's contained in this update, but it's likely that it has a number of bug fixes and security improvements. Microsoft has also released a new version of its Windows Malicious Software Removal Tool for all of its currently supported versions of the OS. Finally, there's a security update for the Flash Player that's embedded in the Internet Explorer browser for Windows 10 as well.
Thanks to Sayan for the tip!
