Windows 10 build 9785

Windows 10 build 9785 is a pre-Technical Preview build of Windows 10. This build was leaked on 19 February 2019. It is very similar to build 9780, which also features a start menu but does not feature windowed Metro applications. Due to its earliness, the build subsequently refers to itself as its predecessor.

This build was released to Microsoft partners participating in the Ecosystem Engagement Access Program (as indicated by the  branch in the watermark). As such, this build can boot on the current date without certificate expiration errors.

Taskbar context menu
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 non-functional version of the Notification Center is present in this build, and is disabled by default.

Settings
Battery Saver is a new feature.

Explorer
New animations are present.

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 taskbar crash
File Explorer may crash if the taskbar context menu is brought up with the right-click button.

Desktop
The positions of desktop icons are not saved upon restart. In addition to this, they will not properly display in Flip 3D.

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.

Incorrect disk space values
The "This PC" folder may incorrectly report available space found in a drive.

Incorrect RAM values in System Properties
The System Properties page may incorrectly report the total amount of installed and usable RAM found on the machine.

Safe Mode
Attempting to boot this build into Safe Mode will result in a black screen.
