Windows 7 build 6730

Windows 7 build 6730 is a Milestone 3 build of Windows 7. It was originally uploaded to BetaArchive on 26 April 2011 and is currently only available as a WIM file.

New features

 * The superbar style has been updated to resemble that of the RTM.
 * Desktop Window Manager 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 now thicker borders and it is smaller.
 * 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 of Windows is not genuine will appear at periodic times, instead of booting into "reduced functionality mode" and an hourly system reboot.
 * Applications such as Paint, Internet Explorer and WordPad have been updated heavily.
 * Show desktop plays DWM animations on windows being minimized and doesn't hide the sidebar.
 * There is now an option in the taskbar properties dialog to configure the superbar (when enabled) to use smaller, "classic" sized buttons and icons. It is called "Use narrow taskbar" instead of "Use small taskbar buttons" as the RTM.
 * The Aero theme have been changed to a kind of hybrid between Vista and 7 style with Vista's glass texture instead of the 7 one seen in build 6608 and the white right and bottom borders like in builds 6568 and 6608.

OEM login screen wallpapers
This is the first available build of Windows 7 that has the ability to change the login screen wallpaper, which was especially made for OEMs. If making a custom login wallpaper yourself, the method is the exact same as that of the RTM release.

OOBE
The Out-of-box experience recieve slight changes. Most notably, at the end, the OOBE now automatically exits and redirects the user to the login.

Installation
This build is only available 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  or   parameters 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.

Desktop Window Manager
The "Aero Peek" function of this build is buggy. 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.

DWM is unstable on certain hypervisors and may crash upon certain events.

Breadcrumbs bar
The breadcrumbs bar is frequently sized incorrectly.

Tahoma
The Windows Basic and Aero themes use the Tahoma font in most places rather than Segoe UI. This quirk was later fixed in build 6780.
