Windows 10 build 20241.1000

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, which were first spotted as a hidden feature in build 20226, are now enabled by default.
 * 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 20231.1000, 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.

Installation bug
"In the guide below, '#' signifies the drive where the mounted ISO is located in setup, while '%' indicates an index in install.wim that is listed by the dism /Get-WimInfo command, while 'X' is the drive (usually 'C') that the operating system is being installed to, and '?' is the volume that contains the majority of the disk space."
 * The ISO files of this build that are stored on the BetaArchive FTP server have a bug that makes it impossible to start setup normally. To bypass it, you must follow the instructions below.
 * Create a VM in VMware as you normally would, but use UEFI instead of BIOS.
 * Start the setup using an ISO of a different build. Proceed normally until you arrive to the drive partition page. Once you're on that page, click on the New button, then click on Apply, then click on OK on the message that appears. After setup creates the partition, insert the affected ISO and then restart the VM.
 * Once you are back on 20241, press SHIFT + F10 to open up Command Prompt.
 * Type in . When   opens, type in   to list the volumes. Assign a drive letter to the volume whose file system is marked as "RAW". This can be done by typing in   ("?" being the number of the volume that usually contains the majority of disk space), then typing in.
 * After assigning a drive letter, check the drive letter assignment by entering in.
 * Exit.
 * After exiting, format the drive by typing in  , then apply the installation image by using DISM.  It is recommended to check the list of SKUs that you want by typing in.
 * Start the installation by using
 * After DISM finishes copying the files, use  to create the boot records on the drive that it was installed on.
 * Restart the VM after all the aforementioned steps are done, and if done correctly, it will proceed like a normal install.

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. It is working properly as of build 20270.
