Windows 8 build 7746

Windows 8 build 7746 is the first available Milestone 1 build of Windows 8 which was uploaded on 3 May 2020, along with screenshots of several other builds. Being very early in development, many areas still include Windows 7 branding and the operating system still uses the version number of 6.1 (much like builds that predate 7875). There are no significant changes from its predecessor, apart from the inclusion of several minor bugs.

New features and changes

 * Unlike build 7700, this build uses the Windows 7 RTM default wallpaper, a change which first occurred in build 7731.
 * The "Send feedback" shortcut returns to the desktop with similar functionality as in Windows 7 build 7000 (albeit with a broken UI) with the inclusion of logging into Product Studio.
 * The preliminary version of Internet Explorer 9 seems to be newer than the one included in build 7700, and does not crash on most websites. However, its rendering capabilities are mostly unchanged.
 * Several kernel exports have been added.

Boot debugging over a network
This build is the earliest available build to support boot debugging over a network. Drivers are included for Realtek RTL8139 and Intel e1000 network cards. As this is an early iteration of network kernel/boot debugging, it does not implement the encryption key system used in the final iteration of KDNET and hence WinDbg with default network debugging settings (which assumes a key) cannot connect to this build's debugging facility.

General
Some included applications do not launch.

Installation
To install this build in VMware, you must set the VM compatibility to 8.x or 9.x or setup will crash with a  bugcheck when attempting to boot the disc image.

Timebomb
Unlike other Windows 8 builds, it contains a broken timebomb and can be installed on the current date.

Personalization
Similar to Windows 7 builds 6936 and 7000, changing themes is not possible if this build is installed on the current date.
