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) and build 10176) are flight-signed builds and have a timebomb hardcoded into the system.

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

 * Snap assist 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.

Window thumbnail border color error
