Windows 10 build 21337.1000

Windows 10 build 21337 (rs prerelease) is the eleventh Insider Preview build of Cobalt. This build was released on 17 March 2021 to all Windows Insiders on the Dev Channel.

Virtual desktop improvements

 * Virtual desktops can now be rearranged from Task View ( Win + Tab ) by either dragging and dropping in the desired place, using the new option in the right click menu to move it one space, or using the Alt + Shift + Left/Right hotkey.
 * Desktop backgrounds can now be chosen individually for each desktop, much like in early Windows Longhorn builds. To do so, go to Settings → Personalization → Background. There, right click a background from the recent list and choose one of the two available options, which apply it to all desktops (the previous behavior) or to a specific one, respectively.

Settings improvements

 * The "Text captions" section under Ease of Access → Hearing has been renamed to simply "Captions". In addition, customizing caption styles has been improved by presenting a single dropdown menu to select default schemes and migrating all options to create new ones into their own page.
 * The options to show the Windows Ink Workspace, Search, Task View, and touch keyboard buttons in the taskbar have been moved from the right click menu on it to Settings → Personalization → Taskbar.

Inbox apps updates

 * The classic Notepad has been replaced by the Microsoft Store version in this build as an inbox app. With version 10.2102.13.0, it brings a new icon and the ability to receive future changes independently from the operating system. Executables from the classic one, however, have been left under  and   which, like with WordPad, open the new version instead.
 * Windows Terminal, with version 1.6.10571.0, has been added as an inbox app for both upgrades and clean installations. It is a modern terminal application for users of command line tools and shells such as Command Prompt, PowerShell, and Windows Subsystem for Linux (WSL) that includes overall customization and functionality improvements over each independent tool.
 * Power Automate Desktop, with version 1.0.30.0, has also been added, and allows to automate web and desktop applications on your Windows desktop by mimicking the user interface actions like clicks, and keyboard input.

Other

 * A new wallpaper has been included under.
 * The default File Explorer layout has been changed, including now more padding within items, which is intended to bring consistency with XAML experiences and improve usability in touchscreens without having to enable tablet mode first. To return to the previous design, go to Control Panel → Appearance and Personalization → Folder Options → View, select the "Use compact mode" checkbox and apply.
 * A preview of Auto HDR has been added, which improves the gaming experience in HDR-capable PCs by delivering HDR visuals on DirectX 11 and DirectX 12 games. This feature can be enabled from Settings → System → Display → Windows HD Color Settings.
 * The new IME candidate window design introduced in build 21313 has been rolled out to all Windows Insiders on the Dev Channel for the Japanese, Chinese Traditional, and Indic IMEs.
 * Emoji search in the new emoji picker now supports the Amharic, Belarus, Cherokee, Filipino, Faroese, Icelandic, Khmer, Mongolian (Cyrillic script), Burmese, Sindhi, Serbian (Cyrillic script), Serbian (Latin script), Swahili, Thai, Turkmen, Tonga, Uzbek (Latin script), and Cantonese (Traditional) languages.
 * Live previews for pinned Microsoft Edge websites to the taskbar are now rolling out to all Windows Insiders on the Dev Channel.

Bugs

 * The update process to this build has a chance of hanging for extended periods of time.
 * Some devices with version 1.0.0.4 of the Realtek network adapter might experience intermittent losses of network connectivity.
 * On some high-refresh monitors, games will be limited to 60Hz while users with variable-refresh-rate monitors may experience tearing issues.
 * On some devices with an NVMe drive, the system may lock-up for up to 30 seconds. This is caused the stornvme driver issuing a reset to the device if it's plugged in to a RAID port.
 * The option to discard changes in custom caption styles is not working in this build.
