Windows 10 build 9834

Windows 10 build 9834 is a Technical Preview build of Windows 10. Screenshots of this build were originally leaked on 11 September 2014. It was later leaked as an x64 Simplified Chinese version on 8 December 2014, followed by x86 versions and other languages later on.

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.

Languages
This build is available in the US English, Japanese, Simplified Chinese, Traditional Chinese, German and Korean languages.

Display drivers
Installing Nvidia drivers on the x64 version of this build breaks DWM resulting in a black screen. A similar bug has also been discovered when installing Intel HD graphics drivers. AMD drivers appear to be unaffected. Older Nvidia devices and drivers (pre-2012) are able to function with DWM disabled.

Timebomb
Unlike other Windows 10 builds, it contains a broken timebomb and can be installed on the current date.

explorer.exe error during shutdown
When you shut down, you may get an error with.

On-screen keyboard
On touch screen devices, on-screen keyboard pops-up only in certain programs. Restarting Windows Explorer can fix this bug.

Remote Desktop Connection
The Remote Desktop Connection client is buggy in this build and is prone to crashing at random intervals.

Window thumbnail color error
Window thumbnails on the taskbar do not change color, but the user can change it after the computer restarts.

Windowed Metro
Occasionally DWM may fail to correctly skin the title bars of windowed Metro apps such as settings. This results in the title bar appearing with the Windows basic theme rather than the Aero theme. Quitting and restarting the affected app will clear the issue.

Persistent Aero Snap sizing
When using Aero Snap to snap a window to the left or right side of a user's monitor, the window will remain at the snapped size even when it is brought out of that snap.
