Windows 10 build 9845

Windows 10 build 9845 is a Technical Preview build of Windows 10 (original release). This build was leaked in German, Japanese, Swedish, Simplified Chinese, Traditional Chinese, and Korean. It is very similar to build 9841. It can also boot on the current date without complaining about expired certificates. Initally, only the Japanese language version of this build was uploaded online in the x64 architecture on 2 July 2015. The rest of the languages were uploaded online two months later on 19 September 2015, along with x86 variants.

This is the last build to be released to Microsoft partners participating in the Ecosystem Engagement Access Program (as indicated by the  branch in the watermark). As a result, all later Windows 10 builds up until the RTM (excluding build 9907 (fbl_ie)) have a timebomb hardcoded into the system, which is currently unable to be removed.

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.

Power options
The power options in the start menu and lock screen are not functional in this build. In order to shut down or restart, it has to be done by right-clicking on the Start button or through the Win + X menu. Alternatively, run either of the following commands through a command prompt or the Run dialog:
 * to shut down the system
 * to restart

PC settings
The Settings application does not start in this build.

Improper Metro effect rendering
This build does not properly render Metro effects and will often display visual artifacts.

Explorer.exe error during shutdown
When the system shuts down, a memory access error related to  may occur.

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.

Translation
Certain strings in the German language versions of this build are either not properly translated or retain their English variants.
