Features[edit | edit source]

The following features and changes introduced previously have been gradually rolled out:

The ability to show the search box on the taskbar set to auto-hide (initially implemented in build 22635.3500 and can be activated manually by enabling the 49287050 velocity staging key)
New shortcut Narrator key+Ctrl+X to copy what Narrator last spoke to clipboard (initially implemented in build 22635.4371)
New functionality in Narrator that reads contents of a mail in the new Outlook app automatically (initially implemented in build 22635.4371)
Update to the "Show location of pointer when I press the Ctrl key" option under the Mouse Control Panel applet so that the circles displayed are now DPI-aware, and aren't really small on high DPI monitors (initially implemented in build 26120.2200)

The following features and changes introduced previously have also been ported to this build, albeit being disabled by default:
