Windows 10 build 9860

Windows 10 build 9860 is a Technical Preview release of the Windows 10 version 1507 development branch. The main addition in this build is a new Windows Phone-style notification area, now known as the Action Center. Otherwise, it is quite similar to 9841.

The buildtag was initially found through the ThresholdInternal build update mechanism on 2014-10-10. The build was released to those signed up to the Windows Insider Program on 2014-10-21 and can be downloaded via the Preview Builds build update mechanism in build 9841.

Installation
Turn off all network adapters even if you set the BIOS date for the machine, otherwise after the hardware setup it will automatically adjust to the current time via online time syncing and thus activate the timebomb, resulting in a BSOD and the bootloader being broken.
