Windows 7 build 6519 is the official Milestone 1 build of Windows 7, which was uploaded to BetaArchive on 10 June 2008.[1] Checked/Debug components from this build were discovered on the Microsoft Symbol Server on 18 June 2022.

New features and changes[edit | edit source]

Hardware support[edit | edit source]

  • This build introduces a feature internally known as “drift correction”, which resolves issues related to CPU clock circuit timing that can potentially prevent services from starting up correctly.
  • The Starter SKU will now recognize more than 1GB of memory.

Boot screen[edit | edit source]

The boot screen itself has been updated to a Vista-style aurora. It also now utilizes BGFX, which was introduced in this build. It allows the boot screen to be displayed in 1024x768 resolution and 32-bit color depth (true color).

However, the older bootvid.dll is still available and still draws the Windows Vista boot screen. It can be forced by executing:

bcdedit /set graphicsmodedisabled yes

Installation and Setup[edit | edit source]

  • As of 2023, this is the earliest build of Windows to include the Deployment Image Servicing and Management tool, commonly known as DISM.
  • Setup no longer disables an upgrade, but it will show the reason in the Compatibility Report after this option has been selected. At this point, the user is not able to go back to the previous page and it only can exit setup. This only affects setup started from Windows.
  • This is the earliest known build to create a "System Reserved" partition, which is used to store the Windows Boot Manager, its boot configuration data (BCD) file, and Windows Recovery Environment. In this build, it is 500MB compared to the 100MB of later builds (and is something that persists up to the latest Windows 10 and Windows 11 builds).
  • The second stage of setup has been completely overhauled, as it only displays a cursor animation and the message that the computer is being set up. This was something that did not ship with the final build and did not come back until Windows 8.
  • The System Assessment now runs before the OOBE starts, and it hides itself under the aforementioned message. This is very similar to what is seen in Windows Vista build 5456.
  • OOBE now has a page for setting up a HomeGroup. This is the earliest available build to have this feature.
  • The EULA now identifies the operating system as "Windows 7" instead of "Windows Vista".

User interface[edit | edit source]

  • Extended the Windows 7 references into more areas of the operating system like the login screen and the About Windows applet.
  • On the watermark, "Windows (R) Code Name "Windows 7"" has been replaced with "Windows (R) 7".
  • The notification area has been updated on both the regular Taskbar and the Superbar, allowing the user to hide notification icons by dragging them to a separate pop-up window.
  • A pin button has been added next to frequent programs in the Start menu.
  • The Start search UI has been made wider.
  • The "Display" option has been added to the desktop context menu.
  • The "How to Share Feedback" program located as a link on the desktop has been revamped and renamed to "Feedback Button" including a new Longhorn-like icon.
  • This build introduced Aero transparency effects even if the window is maximized.
  • The permanent watermark on the Starter SKU was removed.

Winver[edit | edit source]

  • The banner design in the About Windows applet has been overhauled in this build to look more modern, replacing the old banner design that had been in use since Windows 2000.
  • This is the earliest available build to remove the information of the system's RAM on the About Windows applet, which had been present since Windows 1.0.

Windows Explorer[edit | edit source]

  • Windows Explorer can now show previous searches.
  • The search box can now be resized.
  • The User folder has received a new icon.

Applications[edit | edit source]

  • Windows Sidebar has been removed, which allows for gadgets to be placed freely on the desktop. However, the process of the gadgets is still named sidebar.exe and the entry in the Start menu is still named Sidebar.
  • Many of the Windows 7 Calculator features were already included with this build, such as:
    • History
    • The unit converter
    • Statistics and programmer calculator modes
    • Larger equations box
  • An early version of Windows Media Player 12 is included.
  • The home page of Windows Media Center has been updated to use larger title fonts.
  • The ruler has been added to Paint, which can be toggled from the "View" menu.
  • There is a new On-Screen Keyboard hidden in this build, to open it run osk2.exe.
  • Windows Easy Transfer has been greatly overhauled, as it transformed to an Aero wizard. Most notably, a covering wallpaper is no longer in use.
  • Windows PowerShell has been updated to version 2.0.50727.1432. However, the Start menu folder is still named "Windows PowerShell 1.0".
  • "XPS Viewer EP" and "TS Workspace" have been added.

Control Panel[edit | edit source]

  • The main gradient on the left pane has been changed from the green one used in Vista to a bluish one with a different aurora style. Some applets, however, such as Backup and Restore, Windows Update, or Performance Information and Tools, still use the older design.
  • The User Accounts category has been renamed to "User Accounts and Family Safety".
  • Device Center has been added, which would become Devices and Printers in the RTM. Despite the breadcrumbs bar indicating that it is under the Hardware and Sound category when launched from the app's search, the link to it hasn't been added yet, and All Control Panel Items is needed to locate it. Due to its earliness, many devices have blank icons and their properties can't be accessed. In addition, the "Add Loosely Coupled Device" and "Bluetooth Radio" links in the toolbar don't work.
  • Recovery Center has been added, which would be bundled into Action Center in later builds. As with Device Center, it is not present under any category yet and All Control Panel Items is needed to launch it. It contains basic options for device recovery, such as using System Restore or resetting the PC to factory defaults or through a Complete PC Backup.
  • Windows Sensors, which has the same functionality as the Windows SideShow applet from Vista, has been added.
  • Display Settings have been moved to their own "Display" page under Appearance and Personalization, rather than being under the applet in Personalization. When the page is first launched, it provides default scaling options, while screen resolution and custom scaling types still use the previous dialogs.
  • Windows Firewall has been integrated into the Control Panel, rather than being a separate applet. However, Firewall settings are still handled through the legacy dialog.

Hidden features[edit | edit source]

To enable three following features, open the Registry editor, go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced, create a DWORD value called EnableCHS, and set its value to 1.

Superbar[edit | edit source]

This build adds the ability to pin programs to the Superbar.

  • Additionally, labels can be removed from window buttons on Superbar by going to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced, creating a DWORD value called TaskbarAlwaysGlom, and setting its value to 1.

Aero Peek[edit | edit source]

This build introduces Aero Peek, which can be activated by holding down the ⊞ Win+Space keys.

Aero Shake[edit | edit source]

An Aero Shake has been introduced in this build. It minimizes inactive windows by shaking an active one.

Libraries[edit | edit source]

To enable this feature, open the Registry editor, go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced, create a DWORD value called M1FNO, and set its value to 1.

More libraries are now added by default and use new icons. Another library still can be created from navigation pane and setup now does its job properly.

Desktop Background Slideshow[edit | edit source]

This build introduces Desktop Background Slideshow, but it is hidden by default. To enable it, open the Registry editor, go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced, create a DWORD value called EnableDBS, and set its value to 1.

Bugs and quirks[edit | edit source]

Installation[edit | edit source]

  • When installing this build on modern hardware with USB, you must disable USB 3.0 (xHCI) in the BIOS, even if RTM Windows Vista installs fine with it enabled and the drive plugged into the 2.0 ports, as the installer will show an error message that Windows cannot read files.
  • On lower resolutions, the Restarting your computer string gets cut off and reads Restarting your.
  • When setup is about to restart, the text for the 10 second countdown overlaps.

General[edit | edit source]

There is a small graphical quirk with the "Run as Administrator" shield (next to application icons) that appears dithered.

Start orb[edit | edit source]

The Start orb appears after the startup sound plays.

Loading screen[edit | edit source]

The loading screen after setup completes might be stuck loading.
