Windows 10 build 9845

Windows 10 build 9845 is a Technical Preview build of Windows 10. It was initally shared to the public as an x64 version in the Japanese language on 2 July 2015, followed by x86 versions and other languages on 19 September 2015.

This is the last build to be released to Microsoft partners participating in the Ecosystem Engagement Access Program (EEAP), as indicated by the  branch. All later available 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.

New login screen
A new UWP login screen has been added to this build, but it is disabled by default.

zPC settings
In addition to the usual computer settings "PC settings" there is also a “zPC settings”. It also contains settings such as "OEM " and "Pendingor Deprecated” (literally translates to indefinite and obsolete), and judging by the various words inside, it contains a lot of banter.

Other changes

 * Aero Snap has received a small change.
 * CloudExperienceHost app has been added, but it is hidden.
 * Fixed a bug with pop-up text on the taskbar and in the Start menu.

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.
