Time has come for Microsoft to release their first patch for the Windows 7 public beta.

This update is saving your MP3 files from a very annoying bug that trims seconds of any track that’s been edited. If you didn’t back up your library, there’s a big chance that your afflicted files will be saved after installing this patch.

Together with this new update, Microsoft also released a new update for Windows 2000, XP, Vista, and Server 2003 / 2008 fixing a few vulnerabilities in the SMB (Server Message Block) protocol.

According to Christopher Budd, chief of Microsoft Security Response Team beta users will only get their fix only when the next public release because now this is a moderate risk for the new Windows.
