Today Microsoft released Windows 10 Insider Preview Build 18975 (20H1) to Windows Insiders in the Fast ring.  

What’s new in Build 18975

Introducing the ability to move the Cortana window

With the new conversational Cortana experience, Microsoft understands that you want to 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 Microsoft is 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 Microsoft will continue the rollout as Microsoft validates the quality of the experience.

General changes, improvements, and fixes for PC

• Microsoft fixed an issue resulting in the “Bluetooth and Other Devices” and “Printers and Scanners” not rendering correctly in the last two flights.
• Microsoft fixed an issue resulting in search crashing on launch for Insiders using certain display languages, including Polish.

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.
• Microsoft 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, Microsoft has 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.
• Microsoft fixed an issue where the text candidate list, when typing in Korean using the touch keyboard, was in reverse order.
• Microsoft updated the Chinese Pinyin IME toolbar to now be light when using light theme.
• Microsoft 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.

• Microsoft 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.

• Microsoft fixed an issue impacting Action Center reliability in the previous flight.

• Microsoft fixed an issue with Narrator stopping early when reading certain dialogs.
• Based on user feedback, Microsoft 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.
• Microsoft fixed a bug where Narrator did not play the error sound in certain scenarios.
• Microsoft raised the volume of Narrator’s link and scroll sounds.

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. Microsoft will 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. Microsoft is 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. Microsoft is 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. Microsoft is 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. Microsoft appreciates your patience as Microsoft work on a fix.
• Microsoft is 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. Microsoft is 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.
