New features and changes[edit | edit source]

EULA[edit | edit source]

The end-user-license-agreement now references Longhorn instead of Whistler.

User interface[edit | edit source]

Sidebar[edit | edit source]

The taskbar no longer goes through the sidebar, matching the same design present in builds 4001 and earlier.

This build introduces a new "Messenger" tile, which shows the user's online and offline Windows Messenger contacts.

The basket tile now shows 0 items instead of 8. The Tray Icons tile has also been renamed to Classic Tray.

Appearance[edit | edit source]

If a window is maximized, the title bar text is now left-aligned.

Windows Explorer[edit | edit source]

WinFS filters are now grouped, requiring the user to now pick them from a "Pick a" option. Each individual option now allows to stack the contents of the current folder by itself. A "more" option has also been added to "Filter by:", which when clicked, allows the user to choose the details they want to display for the files in the current folder, like "Genre" or "Date Picture Taken".

If there's more than three quick links present, the rest is now grouped into the more option.

The banner found in the Music Library folder is now pink instead of gray.
