Security updates[edit | edit source]

Some security updates were released for this build between October 2008 and February 2009, for x86 and AMD64 architectures (descriptions for which referred to as Windows 7 Pre-Beta), with file versions ranging up to 6801.4xxx.[2][3]

New features and changes[edit | edit source]

Windows Recovery Environment[edit | edit source]

When booting from the onboard Windows RE partition, Startup Repair now launches instead of the System Recovery Options. Startup Repair needs to be canceled to access the Recovery Options.

Personalization[edit | edit source]

Multiple wallpapers can now be selected as default wallpaper, where they will rotate after a specific interval set by the user.

The Personalization Control Panel applet in its whole has been removed from the Starter SKU.

Windows Mail and Calendar[edit | edit source]

The Windows Mail and Windows Calendar applications turned into non-functional stubs, thus are no longer able to be opened. The other files for them are still present though.

Internet Explorer[edit | edit source]

While the version number has been set down from 8.1 to 8.0, a "Suggested Sites" drop-down has been added to the favorites bar.

Windows Media Player[edit | edit source]

The ability to change the background graphics in the Windows Media Player library has been removed.

Bugs and quirks[edit | edit source]

  • Stability issues can be encountered while moving desktop gadgets.
  • Much like in build 6780 and build 6776, in some configurations it is not possible to upgrade to this build without modifying the installer due an error in which "One or more disk volumes present were formatted in an incompatible way by a newer version of Windows". There is only one way to overcome this error, which is to replace the entire installer file (except install.wim) to a newer build or from build 6936.
    • Upgrading from build 6776 will not encounter the bug.
  • In Getting Started, the text below "Find out what's new in Windows" is missing, which results in displaying placeholder text.
