Windows 10 Insider Preview Build 18975 (20H1) released

Microsoft has published the Windows 10 Insider Preview Build 18975 (from the development branch 20H1) for Windows Insiders in the Fast Ring. This build should lead to another function update in spring 2020.

The announcement with details about new features/changes and bugs can be found in the Windows Blog. One of the new features in this build is that the Cortana window can now be moved. Virtual desktops can also be renamed. Here is the list of changes and fixes:

• Microsoft has fixed an issue resulting in the "Bluetooth and Other Devices" and "Printers and Scanners" not rendering correctly in the last two flights.

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.

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.
