Examining and installing a pre-release Windows 7 build (7048?) reveals that there are multiple third-party software companies offering up free trial versions of Windows 7 sounds known as'sound schemes'. These sound scheme trial versions are almost identical to the full Windows 7 sounds, except the user interface, and they lack the 'Live' functionality (i.e., they cannot be replaced or dynamically altered by the user, which is what Windows 7 users expect in Vista sounds).
The current format of the Sound Schemes sounds is in FLAC format. Many of the sound schemes are identical both to each other and the full sound, even though the sound scheme was created in a very different build of Windows (the old Vista). These sound schemes contain the same types of background sounds as the full sound, including instrumental music, environmental impacts, an interactive environment, and both types of sounds. Some of the sound schemes contain additional sounds such as dramatic impacts, work-related sounds (including typing on a keyboard), and many others. The typical sound scheme is almost identical to Windows Vista -only in a different skin and context. While current sound schemes resemble Vista sounds more than Longhorn sounds, they can be easily downloaded and installed on current Windows, not used with a pre-release Windows 7 build.
Somewhere over the past 24 hours or so, an upsurge in the popularity of Windows 7 and Internet Explorer 8 seems to have caused some browsers to render the surface browser elements with the Aero interface and others without. The problem seems to have been fixed, but apparently not everyone has had trouble seeing the concept of the new user interface, and as a result many browsers have not updated their document. Another problem is that IE 8 is no longer available (or was not) for download as of this post, and changing the theme settings does nothing. That is, while the new GUI elements are present, nothing will change the appearance of your web browser. d2c66b5586
