Windows 10 build 9834

Windows 10 build 9834 is a Technical Preview build of Windows 10. Screenshots of this build were originally leaked on September 11, 2014. It was later leaked as an x64 Simplified Chinese version on December 8, 2014, followed by x86 versions and other languages later on. As with other builds in the fbl_partner_eeap branch, it can also boot with the current date without complaining about expired certificates, because it is test-signed, not flight-signed.

Languages
This build was leaked in US English, Japanese, Simplified Chinese, Traditional Chinese, German, and Korean.

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.

On-Screen Keyboard
On touch screen devices, On-Screen Keyboard pops-up only in certain programs. Restarting 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.

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.
