Windows 7 build 6730

Windows 7 build 6730 is a Milestone 3 build of Windows 7 that was only leaked in WIM format. This build includes Aero theme updates and Internet Explorer 8. It was leaked to BetaArchive on 26 April 2011.

New features

 * The superbar style has been updated and resembles that of the RTM.
 * DWM applies colorization differently, using a "color dodge" effect. This effect was removed from active windows in build 6780.
 * An early version of the Aero Snap feature is implemented. The window is resized instantly to the snap rather than showing an outline before the user releases the window drag.
 * A small bar will appear in Explorer when performing a "typing scroll." This may be accessed when a user types keys after highlighting an item in the main section of an Explorer window.
 * A new boot screen is shown in this build, it is similar to the one found in build 6519 and 6608.
 * The start orb has a slightly different appearance.
 * The start menu has been modified.
 * Internet Explorer has an "emulate IE7" feature and is the earliest version of Internet Explorer with developer tools.
 * User Account Control's dialogs now resemble the ones that are found in the RTM.
 * Windows Activation now behaves like on Windows Vista Service Pack 1; all premium features (including Windows Aero) will remain functional and a dialog warning the user that the copy is not genuine will appear at periodic times, instead of booting into "reduced functionality mode" and an hourly system reboot.
 * Applications such as MSPaint, Internet Explorer and WordPad have been updated heavily.
 * Show desktop plays DWM animations on windows being minimized and doesn't hide the sidebar.

Installation
This build only leaked in WIM format (different format than the ones that are used in WinPE), you can either convert the WIM to VHD and mount it to a virtual machine, or apply the WIM to a partition of a virtual drive:


 * 1) Partition and format a blank virtual hard drive.
 * 2) Mount the drive and use an utility such as GImageX to apply the WIM to the hard drive.
 * 3) Unmount the drive and install normally.

Attempting to install this build normally will result in an error while installing updates, possibly due to incorrect ACL permissions with one of the registry keys in the system hives.

Bugs

 * The "Aero Peek" function of this build is broken. It may not show a window thumbnail and may frequently crash Explorer as well. To prevent crashing, avoid moving the mouse to the taskbar window thumbnail.
 * The breadcrumbs bar is frequently sized incorrectly.
 * DWM is unstable on certain hypervisors and may crash upon certain events.
