Microsoft has issued it's first patch for the Windows 7 beta—a fix that focuses on correcting a flaw that shaves several seconds off edited MP3s.
Up until now, this patch had to be found and installed manually—but if you missed it, a recent Microsoft patch article notes that it may be possible to restore any corrupted MP3 files by right-clicking into "Properties" and clicking "Restore" in the "Previous Versions" tab. Even so, its a good idea to back up all of your MP3 files before doing an upgrade from Vista to Windows 7. [Computerworld]
