Windows 10 build 18267

Windows 10 build 18267 is the tenth Insider Preview build of Windows 10 May 2019 Update. This build was released to Windows Insiders in the Fast Ring on 24 October 2018.

General

 * You can now use the the Telex input method for typing the Vietnamese language, as well as a number-key based keyboard for inputting said language (it has to be downloaded first, as it does not come bundled with the operating system). To install these input methods, open the Settings app, then navigate to the Time and language section, once there, click on the "+" icon, type in Vietnamese in the search box, and install it by clicking on the next button. After that is done, click on the Vietnamese selection, and then click on the options button, which takes you to the options of that language, from there select the "+" button labeled "Add a keyboard", and if present, enable either of the two keyboards: Vietnamese Telex keyboard or Vietnamese Number key-based keyboard. When that task is done, select the input indicator icon on the system tray (or press Win+Space ) and select either of the two new input methods.
 * You can now access more symbols, special characters and accented letters directly from the touch keyboard. It can be accessed by changing to the numbers & symbols view (&123) and by selecting a new omega (Ω) icon.
 * Added a new feature that allows Windows to search all of the user's folders and drives, instead of limiting search to their documents, pictures, videos, and desktop by default. To enable it, navigate to the Cortana section, and then go to the "Searching Windows" page. Once there, turn on the "Enhanced" slider located under the "Find my files" section to start the one-time indexing process. Folders can be added to a exclusion list if you don't want the system to search the contents of that folder.

Accessibility improvements

 * Drastically improved the support for Narrator with Google Chrome. It now supports using the up and down arrows while in scan mode, navigating using the Tab key, continuous reading commands, as well as navigating by headings and links.
 * BRLTTY version 5.6 is now included, which adds USB support for Inceptor and Orbit 20 displays. The BrailleNote Touch is now recognized when using a USB. Baum displays can now use B9 and B10 interchangeably. The Liblouis binaries and tables have been updated to version 3.7.0.
 * The UI Automation framework now supports translating IAccessible2 information from Chrome, which supports IAccessible2 rather than UI Automation. This enables clients that use UI Automation to receive the IAccessible2 information through the UI Automation client interfaces.

Bugs

 * You cannot create more than two virtual desktops, because after creating one, the + button on the "New desktop" selection disappears.
 * Sometimes the update status can cycle between Getting Things Ready, Downloading, and Installing. It is often accompanied by error 0x8024200d, which is caused by a failed express package download.
 * Changing the Task Manager settings will revert them to the default the next time it is opened.
 * If there's a large amount of OTF fonts present, or OTF fonts that support the extended East Asian character set, some text across the system may be unexpectedly missing. Opening the  folder should resolve this glitch.
