The updated emoji picker and touch keyboard from build 20206 were enabled only on upgraded installations.
== Bugs ==
* New applications will fail to install and instead return with a Windows Installer service error on x86 versions of this build.
* Attempting to perform a Reset this PC operation using the Keep My Files option will fail with the error “There was a problem resetting your PC. No changes were made”.
* The update process to this build has a chance of hanging for extended periods of time.
* Live preview doesn't work for pinned site tabs on some machines, a gray window is seen instead of the intended content.
* There's a chance of randomly encountering a BSOD with the error code KMODE_EXCEPTION when using certain virtualization technologies.
* Selecting an IME candidate or hardware keyboard text prediction candidate may insert the candidate adjacent to the one selected.
* On 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 ().
* There's a chance of randomly encountering a APC_INDEX_MISMATCH BSOD.
* GPU Compute scenarios, such as using CUDA and DirectML, are not working inside of the Windows Subsystem for Linux.
* Windows PowerShell does not work on the ARM64 versions of this build. To use the app, open up “Windows PowerShell (x86)” or “Windows PowerShell ISE (x86)”, which is located on the Start menu instead.
=== Installation ===
* Some UUP-converted ISOs of this build have a bug that causes setup to encounter an error when attempting to start setup normally. This includes the copies stored on the BetaArchive FTP server. To bypass it, follow the instructions below.
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.
**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 20236, press to open up Command Prompt.
** Type in diskpart. When diskpart opens, type in list vol 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 select volume ? ("?" being the number of the volume that usually contains the majority of disk space), then typing in assign.
**After assigning a drive letter, check the drive letter assignment by entering in list volume.
**Exit diskpart.
**After exiting diskpart, format the drive by typing in format x: /fs:NTFS, then apply the installation image by using DISM. It is recommended to check the list of SKUs that you want by typing in dism /get-wiminfo /wimfile:#:\sources\install.wim.
**Start the installation by using dism /apply-image /imagefile:#:\sources.install.wim /index:% /applydir:X:\
**After DISM finishes copying the files, use bcdboot X:\Windows 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.
== Updates ==
