Windows 10 build 18912

Windows 10 build 18912 is the fifteenth Insider Preview build of Windows 10 May 2020 Update. This build was released to Windows Insiders in the Fast Ring on 5 June 2019. This build was originally released with the Home, Pro, Enterprise and Education SKUs only, and thus the Cloud SKU of this build was not present. However, a copy of the Cloud SKU containing this build in Simplified Chinese was uploaded to the Internet Archive on 4 October 2022. Prior to it being uploaded, it was present in a torrent from the Chinese software preservation group 老光盘交流群 from 13 June 2019.

New changes

 * Some improvements were made to the "click me" function of Narrator. These include Narrator now telling the user the title of a page that the app is linked to, to do this, press ⇩ CapsLk and Narrator will take the URL of the hyperlink that the user is on and send it to an online service that provides the page title to Narrator. It can be turned off via the Narrator settings.
 * Bugfixes and general improvements listed in the official announcement.
 * Some Windows Insiders at the time of this build's release had an altered version of Windows Ink Workspace. It had a smaller appearance and contained a direct link to the Microsoft Whiteboard app.
