Windows 10 build 9785

Windows 10 build 9785 is a pre-Technical Preview build of Windows 10, was uploaded to BetaArchive on 19 February 2019. This build was originally released to Microsoft partners participating in the Ecosystem Engagement Access Program (EEAP), as indicated by the  branch.

Due to its earliness, this build is identified as Windows 8.1 branding in many areas and still has kernel version 6.3.

Taskbar
The context menu appearance for pinned or running applications on the taskbar now changes color according to the user's color preferences. However, the auto-colorization functionality for the context menu does not work.

Notification Center
A new Notification Center has been introduced, although it is not functional yet and is disabled by default.

Settings
The option to enable Battery Saver has been added to Settings.

Timebomb
Like other Windows 10 builds found in the  branch, this build contains a non-functional timebomb and as a result can be installed on the current date.

File Explorer
File Explorer may crash if the taskbar context menu is brought up with the right-click button. The icon positions on the desktop and in File Explorer are not saved when updating. In addition to this, they will not properly display in Windows Flip.

Window thumbnail border color
If window auto-colorization is enabled, the window thumbnail borders on the taskbar do not change color even after the wallpaper changes. This issue can be remedied by manually changing the window color through the Control Panel.

Safe Mode
Trying to boot into Safe Mode (whether via msconfig or Recovery Options) results in a black screen.
