Windows 10 build 9785

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

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

Timebomb
Like other builds found in the  branch, this build uses a test-signed certificate and as a result can be installed on the current date. However, installing this build on the current date disables the ability to change the desktop wallpaper in the Control Panel.

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

File Explorer

 * The "This PC" folder may incorrectly report the amount available space on a drive.
 * File Explorer may crash if you open the browser's jump lists in the taskbar and start menu.
 * 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.

Control Panel
The System Properties page may incorrectly report the total amount of installed and usable RAM found on the machine.

Windows Anytime Upgrade
If you upgrade to the Professional with Windows Media Center SKU, Media Center will not work.

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