Microsoft’s Latest Windows 10 20H1 Preview Arrives with SwiftKey Intelligence Expansion

Microsoft has rolled out a new Windows 10 20H1 preview (build 18860) to Insiders on the Skip Ahead branch, while the company also explained when Win10 19H2 previews will begin.


Over the last two months, we have been charting 's development of on the branch. Today, the company has rolled out Preview Build 18860 to Windows Insiders brave enough to be using an OS that over a year from being launched.

Interestingly, Microsoft is testing Windows 10 20H1 before it has rolled out previews for Windows 10 19H2. And indeed, before is launched Windows 10 19H1 next month. We have discussed the odd situation in previous 20H1 preview posts, and Microsoft has acknowledged the bizarre testing formula in its Windows blog:

“We will begin releasing 19H2 bits to Insiders later this spring after we get 19H1 nearly finished and ready; once 19H1 is “nearly finished and ready” we'll also use the Release Preview ring for previews of drivers and quality updates on 19H1.”

Before getting into what's new, it is worth noting any features testing in Windows 10 20H1 will not be with end users until around April 2020. That said, Windows 10 Preview Build 18860 furthers intelligent typing on SwiftKey.


Microsoft has been developing typing intelligence on the keyboard app for some time. Now the company says this support will be expanded to 39 new languages:

“Afrikaans (South Africa),  Albanian (Albania),  Arabic (Saudi Arabia),  Armenian (Armenia), Azerbaijani (Azerbaijan), Basque (Spain), Bulgarian (Bulgaria), Catalan (Spain), Croatian (Croatia), Czech (Czech Republic), Danish (Denmark), Dutch (Netherlands), Estonian (Estonia), Finnish (Finland), Galician (Spain), Georgian (Georgia), Greek (Greece), Hausa (Nigeria), Hebrew (Israel), Hindi (India), Hungarian (Hungary), Indonesian (Indonesia), Kazakh (Kazakhstan), Latvian (Latvia), Lithuanian (Lithuania), Macedonian (Macedonia), Malay (Malaysia), Norwegian (Bokmal, Norway), Persian (Iran), Polish (Poland), Romanian (Romania), Serbian (Serbia), Serbian (Serbia), Slovak (Slovakia),  Slovenian (Slovenia), Swedish (Sweden), Turkish (Turkey), Ukrainian (Ukraine), Uzbek (Uzbek)”

For users running Windows 10 and SwiftKey in those languages, this change means typing accuracy and autocorrect suggestions will be improved. Through machine learning tools, the keyboard will surface more accurate predictions when a user starts typing.

As usual, Microsoft has detailed the fixes and known issues in this build:


  • We fixed a Microsoft Edge crash encountered when interacting with combo boxes in PDF forms.
  • We fixed an issue that could result in night light being on after an upgrade, even though all the settings showed that night light should be off.
  • Fixed an issue where using the slider to adjust the night light strength could result in night light getting stuck on.
  • We fixed an issue where night light was skipping the fade transition when it was turned off (manually or scheduled).
  • We fixed an issue resulting in increased battery drain while the screen was on in recent builds.
  • Fixed an issue resulting in the “…” menu contents being clipped for certain apps like Voice Recorder and Alarms and Clock when the app was full screen.
  • We fixed an issue resulting in some Insiders experiencing bugcheck green screens citing a KERNEL_SECURITY_VIOLATION error.
  • We fixed an issue preventing certain VMs from being able to install or update Windows Insider Preview builds. The VM would hang on the black screen with the Windows logo.

Known Issues

  • Launching games that use anti-cheat software may trigger a bugcheck (GSOD).
  • When performing Reset this PC and selecting Keep my files on a device that has Reserved Storage enabled. The user will need to initiate an extra reboot to ensure Reserved Storage is working again properly.
  • Some Realtek SD card readers are not functioning properly. We are investigating the issue.
  • Creative X-Fi sound cards are not functioning properly. We are partnering with Creative to resolve this issue.
