Yesterday, Microsoft released Windows 10 for PCs Insider Preview build 16353 to Insiders in the Fast ring that chose the Skip Ahead option. That doesn't mean that regular Fast ring Insiders are done getting new builds though, as 16281 was released today.
We're getting closer and closer to an RTM, as the firm announced this morning that the Fall Creators Update will arrive to the public on October 17, and that also means that there are no new features. Instead, Microsoft is focusing on fixes and improvements at this point.
Here's what got fixed and improved in build 16281:
We fixed an issue resulting in Train Simulator 2017 failing to launch on recent flights.
We fixed an issue resulting in not being able to tab into an open PDF in Microsoft Edge after interacting with the any of the Microsoft Edge window elements using mouse.
We fixed an issue where the Windows Defender Security Center app icon was missing in taskbar when the app was open, as well in Start’s all apps list. You will also notice that the icon is now un-plated in the taskbar.
We’ve made some adjustments to address an issue resulting in sudden and brief CPU spikes where you couldn’t move your mouse. If you’ve encountered this, please try it in this new build and let us know if your experience has improved.
We fixed an issue where minimized app windows on mixed-DPI monitor setups might end up drawing offscreen after your PC resumed from sleep.
We fixed an issue where if you changed your display language preference to something other than the machine’s default then any app which did not take an update while also getting the updated language resource package from the Store would end up continuing to display its tile in Start in that default language rather than the new language displayed within the app and other system UI.
There were no known issues listed in the changelog, but that doesn't mean that there aren't any. Microsoft's Brandon LeBlanc said last week that the company won't be listing them anymore, as it finalizes the Fall Creators Update.
It seems likely that an RTM build will arrive later on this month, and once it's official, we'll see it in the Release Preview ring of the Insider Program.
