First off, there is the Fast build 17763. Again, this build is fairly minor and doesn’t back any new features. It is instead focused on fixing issues with Bluetooth, OneNote, and Powershell. There are also known issues with this time around, covering Task Manager and Background processes. Here’s what you need to know.

General changes, improvements, and fixes for PC:

• The build watermark at the lower right-hand corner of the desktop is no longer present in this build. This doesn’t mean we’re done…
• We fixed an issue where touching a Flash element in Microsoft Edge with two or more fingers could result in the tab crashing.
• We fixed an issue where thumbnails and icons might not be rendered if there were any video files saved to the desktop.
• We fixed an issue where certain Bluetooth audio devices wouldn’t play sound in apps that also used the microphone.
• We fixed an issue resulting in an unexpectedly increased use of battery recently when using certain apps like OneNote.
• We fixed an issue in PowerShell where it wasn’t displaying characters correctly in Japanese.
• We fixed an issue resulting in display scaling factors not being applied correctly (so the UI was smaller than expected) when viewing a full screen remote desktop window on a monitor set to certain display scalings.

Known Issues:

• Task Manager is not reporting accurate CPU usage.
• Arrows to expand “Background processes” in Task Manager are blinking constantly and weirdly.

Next up, there is the Slow ring Cumulative Update Build 17758.1004. There’s nothing much to note here, as this release includes all the releases from build 17760, which was just pushed out last week. That mainly helps address issues with .NET, PDFs, and other issues in Edge. We recapped those issues right here, so feel free to check it out.

Both these builds dropped right as Microsoft’s monthly Windows Insider webcast is underway. Feel free to give that a watch while your new builds download, and drop us a comment below once you’re running the latest releases to let us know how it is working for you.
