Announcing Windows 10 Insider Preview Build 18975



Hello Windows Insiders, today were releasing Windows 10 Insider Preview Build 18975 (20H1) to Windows Insiders in the Fast ring.  

NOTE: If you have Centennial Office installed from the Microsoft Store, you won’t be offered this build.

IMPORTANT: As is normal with pre-release builds, these builds may contain bugs that might be painful for some. If you take this flight, you won’t be able to switch Slow or Release Preview rings without doing a clean-install on your PC.  

 If you want a complete look at what build is in which Insider ring, head over to Flight Hub. You can also check out the rest of our documentation here including a complete list of new features and updates that have gone out as part of Insider flights for the current development cycle.  

Not seeing any of the features in this build? Check your Windows Insider Settings to make sure you’re on the Fast ring. Submit feedback here to let us know if things weren’t working the way you expected. 

What’s new in Build 18975

Introducing the ability to move the Cortana window

With the new conversational Cortana experience, we understand that you wanna keep the chat going sometimes, and the default position of the window isn’t always where you’d prefer to have it docked if you’re going to have a longer back and forth. That’s why we’re starting to roll out the option to be able to move the window (by dragging the title bar area), to anywhere you’d like on the screen–just like you can with other windows. You can also resize the window if you’d like. Currently, this change is rolled out to 50% of Insiders with the new Cortana experience, and we’ll continue the rollout as we validate the quality of the experience.

Demoing the ability to make Cortana's window smaller, as well as move it around.

General changes, improvements, and fixes for PC

  • We fixed an issue resulting in the “Bluetooth and Other Devices” and “Printers and Scanners” not rendering correctly in the last two flights.
  • We fixed an issue resulting in search crashing on launch for Insiders using certain display languages, including Polish.
  • We fixed an issue resulting in some Insiders receiving error 0xC0000142 when attempting to upgrade to recent builds.
  • We fixed a recent issue resulting in some Insiders finding that various File Explorer settings were unexpectedly modified, and in some cases couldn’t be corrected. This impacted File Explorer’s navigation pane visibility, the option for the navigation pane to automatically show all folders, and showing the drive letters. Please note that while this fix will stop it from happening, if you were impacted, you will need to take steps to return these settings in File Explorer to be their desired state.
  • We fixed an issue resulting in the minimize, maximize, and close title bar buttons not working for certain apps.
  • For those who would prefer not to see the post upgrade setup page, we’ve added a new option to turn it off under Notification Settings. Note, it will only be visible for users eligible for seeing this setup page.
  • We fixed an issue where the text candidate list, when typing in Korean using the touch keyboard, was in reverse order.
  • We updated the Chinese Pinyin IME toolbar to now be light when using light theme.
  • We fixed an issue that could result in the Chinese Pinyin IME not responding the first time you tried to select a text candidate in certain types of text fields.
  • We fixed an issue that could result in the mouse cursor becoming transparent and not visible when HDR was enabled.
  • We fixed an issue where if MS Paint was open in the background, using the arrow keys would result in the mouse cursor changing position despite MS Paint not being in focus.
  • We fixed an issue when using your PC in Arabic or Hebrew, where when maximizing win32 apps you could see the title bar flip for a second to show the close button on the right instead of on the left.
  • We fixed an issue impacting Action Center reliability in the previous flight.
  • We’ve made some adjustments to help address potential out of memory issues over Remote Desktop that could result in you being unexpectedly logged out of your remote session.
  • We fixed an issue resulting in not being able to setup Windows Hello during OOBE.
  • We’ve updated our upgrade logic so that going forward, your preferred scheduled defragmentation settings will be preserved on upgrade. Thanks to those who shared feedback about this.
  • We’ve made some improvements to help address out of memory issues resulting in users potentially getting logged out of remote desktop sessions.
  • We fixed an issue impacting Your Phone reliability in recent flights that resulted in seemingly random crashes during use.
  • We fixed an issue where, when taking a screenshot using the pen after rotating your device, the screenshot might not be in the expected orientation.
  • We fixed an issue when taking a snip that could result in your screenshot being unexpectedly blacked out.
  • We have removed the option to change Magnifier UI to a magnifying glass and be in the viewport. We would be interested to hear if this option was useful to you and why.
  • Magnifier reading now supports reading in more places.
  • Several issues have been resolved that caused the Magnifier UI not to scale or resize correctly when users adjusted the Make text bigger or the Make everything bigger settings.
  • We resolved an issue where users could not use some Magnifier hotkeys after sign-in until Magnifier was restarted.
  • We resolved an issue where Magnifier Docked and Lens mode would turn into Full Screen mode when User Account Controls were active.
  • We resolved an issue in Notepad where the text cursor would display, but the text cursor indicator would not.
  • We resolved an issue in Notepad where the text cursor indicator prevented users from double-clicking to select text.
  • We resolved an issue where the text cursor indicator preview in Ease of Access settings was not usable when Dark Mode is enabled.
  • We resolved an issue where the text cursor indicator was randomly filling in with black.
  • We fixed an issue with Narrator stopping early when reading certain dialogs.
  • Based on user feedback, we enhanced Narrator’s reading experience when arrowing through messages in Outlook. When the importance column is read the “importance” header is always spoken before the high or low. If a message has been flagged that column’s information will be spoken immediately after the importance column instead of at the end.
  • We fixed a bug where Narrator did not play the error sound in certain scenarios.
  • We raised the volume of Narrator’s link and scroll sounds.
  • We fixed a bug when the Narrator page summary was not working in the Chrome browser.
  • We fixed a bug where assistive technology (e.g. Narrator, Magnifier, NVDA) were starting after sign-in when only the before sign-in setting was set.
  • Narrator is now presenting “flash messages” on a configured braille display as expected for reading the window title and when presenting suggested content.
  • Narrator is now presenting cell contents on a configured braille display as expected when navigating a table.

Known issues

  • The Reset this PC cloud download option is not currently calculating the correct amount of space you need to free up if you do not have enough disk space to proceed. To work around this until the fix is available, free up an extra 5GB beyond what is prompted.
  • The Reset this PC cloud download option is not currently working when specific optional features are installed. The process will begin, but an error will occur and roll back the changes. To work around this issue, remove the optional features before trying the cloud download option. We’ll let you know once this issue has been resolved. The optional features are: EMS and SAC Toolset for Windows 10, IrDA infrared, Print Management Console, RAS Connection Manager Administration Kit (CMAK), RIP Listener, all RSAT tools, Simple Network Management Protocol (SNMP), Windows Fax and Scan, Windows Storage Management, Wireless Display, and WI SNMP Provider.
  • There has been an issue with older versions of anti-cheat software used with games where after updating to the latest 19H1 Insider Preview builds may cause PCs to experience crashes. We are working with partners on getting their software updated with a fix, and most games have released patches to prevent PCs from experiencing this issue. To minimize the chance of running into this issue, please make sure you are running the latest version of your games before attempting to update the operating system. We are also working with anti-cheat and game developers to resolve similar issues that may arise with the 20H1 Insider Preview builds and will work to minimize the likelihood of these issues in the future.
  • Some Realtek SD card readers are not functioning properly. We are investigating the issue.
  • Some Insiders may experience a deadlock in netprofmsvc.dll on Builds 18967+. This can result in the upgrade to the build freezing at 98%, or if you’re on the build already you may find that various aspects of the system unexpectedly freeze and become unresponsive. We appreciate your patience as we work on a fix.
  • We are looking into an issue where, after updating to this build, adding a new Language Pack reports successful installation but is not installed.
  • There is an issue with this build where certain Local Experience Packs (LXPs) may revert to English. We are working on a fix.
  • Certain 2D apps (like Feedback Hub, Microsoft Store, 3D Viewer) are incorrectly being treated as having protected content within Windows Mixed Reality. During video capture, these 2D apps block their content from being recorded.
  • When capturing a repro video while filing a bug via Feedback Hub in Windows Mixed Reality, you won’t be able to select Stop video, due to the protected content issue noted above. If you want to submit a repro video, you will need to wait 5 minutes for the recording to time out. If you’d like to file the bug without a repro video, you can close the Feedback Hub window to end the recording and resume filing your bug when you reopen the app in Feedback > Drafts.

Save the Date: The 20H1 Bug Bash is coming!

We’re planning to run this bug bash from September 25th to Oct 2nd –we’ll have more details to share closer to the date.
