As is the custom Microsoft is using the Week End to publish a new build of Windows 10. This 20H1 Build 18985 offers improvements in wireless Bluetooth technology.

Features & improvement

Windows 10 20H1 Build 18985 is available for download for registered users on the Windows Insider Quick Ring. This release brings some new features, improvements and bug fixes. One of the most striking facts concerns Bluetooth technology and more specifically the Bluetooth coupling experience. The giant improves its Swift Pair system introduced by April 2018 Update.

From now on, all the coupling will take place in the notification. It is no longer necessary to go to the settings to complete the process. Redmond removes a notification and adds a new button named “Dismiss”. This new system is available for 50% of users of the fast ring. It supports Surface Ergonomic Keyboard, Surface Precision Mouse, Microsoft Modern Mobile Mouse, Surface Mobile Mouse, Microsoft Arc Mouse, Surface Arc Mouse and Surface Headphones peripherals.

In parallel, changes are made around optional updates. The operating system offers a “refined” experience. Dona Sarkar, Windows Insider Program Manager explains

Once the optional updates are detected, they are listed in a new page located in :

Settings> Update and Security> Windows Update> View Optional Updates.

For drivers, you no longer need to browse Device Manager to find a specific device to update. Windows Update automatically keeps your drivers up-to-date, as before, but in case of problems, one of these optional drivers might help you.

The Snip & Sketch app benefits from extensive editing. Note that all users of the Release Preview ring are now affected by the same version v10.1907. It offers a unique window mode and zoom support.


Microsoft explains that it will no longer be necessary to check for updates in the device manager. These will always be updated automatically if there is a critical fix, but if there is a problem with one of them, this new window will make it easy to see if a new optional driver is available.

Release date of Windows 10 20H1 build 18985 

The build 18985 of Windows 10 20H1 is distributed to the testers members of the program Windows Insider who use the fast channel. The new features presented here may not be activated immediately for everyone since the installation as Microsoft has been in the habit of doing for some time. The stable version of Windows 10 20H1 will only be available in the spring of 2020 and many more new features should be available by this deadline.

Finally Microsoft offers many small improvements here and there and some bug fixes. The release note also announces known and uncorrected issues. All details are available at the end of the article.

Windows 10 build 18985, release note

General changes, improvements, and fixes for PC :

  • We have successfully added a new language pack.
  • We fixed an issue impacting the reliability of Settings when accessing the Network & Internet section.
  • We fixed an issue that could not be used properly for not-admin accounts-the text overlapping, and not being clickable.
  • We fixed an issue resulting in an unexpectedly high temperature for some GPUs.
  • We fixed an issue resulting in Task Manger unexpectedly showing 0% CPU usage in the Performance tab.
  • We fixed an issue where the setting that allows us to access the password (by requiring Windows Hello sign in and hiding the password option from the lock screen). Now the setting will only show for Microsoft account users.
  • We fixed an issue with the Reset this PC cloud download option not calculating the correct amount of space you need to free up if you did not have enough disk space to proceed.
  • We fixed an issue with this option.
  • At this time, we’re removing our known issue of Realtek SD card readers. If you are still encountering issues with any SD card, please take a moment to check for driver updates, and file feedback if it does not resolve it for you.

Known issues :

  • There have been some issues with older versions of PCs to experience crashes. We are working with partners on their software, and most games have released patches to prevent PCs from this issue. To minimize the risk of running into this issue, please make sure you are running the latest version of your operating system. We are also working with anti-cheat and game developers to resolve the issue of insecurity in the future.
  • Some 2D apps (like Feedback Hub, Microsoft Store, 3D Viewer) are incorrectly being treated as part of Windows Mixed Reality. During video capture, these 2D apps are blocking their content from being recorded.
  • When capturing a repro video while filing a bug via Feedback Hub in Windows Mixed Reality, you will not be able to select. If you want to submit a repro video, you will need to wait 5 minutes for recording to time out. If you’d like to file a bug with a repro video, you can close the Feedback to a friend.
  • When viewing Optional drivers in the new section on the Windows Update. If accepted, they will attempt to install and fail to do so. This is a bug related to revised Windows Update detection logic rather than this new UI. The root cause is understood, and will be available in an upcoming build.
