Windows 10 build 20246.1

Windows 10 build 20241.1000 is the eighteenth Insider Preview of Iron. A screenshot was shown by a Microsoft employee on 19 October 2020, and the build itself was released two days later to all Insiders on the Dev Channel.

Changes
"Some of these changes are only available to a small group of Insiders, meaning that not everyone will see them right out of the box, and will roll out to the rest of Insiders soon."


 * Theme-aware splash screens were introduced.
 * Japanese Address and Rinna candidate suggestion services from the Japanese IME were removed.
 * Drive Optimizer improvements.
 * Added an "Advanced View" checkbox, which lists all drives, including hidden ones.
 * More details on the "Current status" tab are available when a drive is not available for defragmentation, such as "Partition type not supported" or "File system type not supported" messages.
 * Support for refreshing the drives table using the F5 key has been added.

New OOBE updates
While the new Out of Box Experience, which was first spotted in build 20231, is still a hidden feature in this build, it has been updated, including the following:


 * The background is no longer blank, and it is similar to that seen in Windows 10X.
 * Performance without graphics drivers has been improved. While some animations are still somewhat laggy, the time when switching from one page to another has been reduced by this point.
 * The strange keyboard input bug has been fixed.

Bugs

 * Live preview doesn't work for pinned site tabs on some machines.
 * Some virtualization software have a chance of giving you a BSOD with the error code.
 * There's a chance of randomly encountering a  BSOD.
 * There's a chance of randomly encountering a  BSOD on.
 * In some PCs, the taskbar is obscuring the Power button in the Start menu blocking the access to its options. To workaround this issue, use the options from the User menu (Win+X).
 * Devices running Malwarebytes Web Protection are no longer able to connect to Internet. To workaround this issue, disable the feature from the Malwarebytes dashboard.
 * GPU Compute scenarios, such as using CUDA and DirectML, are not working inside of the Windows Subsystem for Linux.
 * ARM PCs will notice that Windows PowerShell will fail to launch on this build. To workaround this issue, use PowerShell (x86) and PowerShell ISE (x86).
 * The "Advanced View" Drive Optimizer enhancement is still at an early state, and clicking it will do nothing.
