These white papers provide information about Binary Delta Compression (BDC) technology and its use in deploying software updates for Microsoft® Windows® XP, Windows Server™ 2003, and Windows 2000 operating systems. BDC is a differential compression technology that reduces the download size of software update packages.

Binary Delta Compression (BDC) technology helps reduce the download size of software update packages for Windows operating systems. BDC works by compressing and downloading only the differences between old files and new files, thereby creating smaller software update packages that require less time and network bandwidth to install. Files downloaded from later versions of Microsoft Windows Update also support the use of the Background Intelligent Transfer Service (BITS), which asynchronously transfers update files, preserves the responsiveness of other network applications, and automatically resumes file transfers after restarts or network disconnects. In addition, update installations that use the latest version of the Microsoft Software Update Services (SUS) client no longer require Microsoft Internet Information Services (IIS) server but can download updates from any server that supports HTTP 1.1, thereby reducing server traffic. Together, BDC and BITS can help streamline the process for downloading critical and security updates.

  • For information about updating Windows 2000 using BDC, see the white paper “Binary Delta Compression″ (BDC_v1.doc).
  • For information about updating Windows XP and Windows Server 2003 using BDC, see the white paper “Using Binary Delta Compression (BDC) Technology to Update Windows XP and Windows Server 2003″ (BDC_v2.doc).

      What is this?

      Microsoft regularly deletes downloads for prior versions of Windows, Office, Visual Studio, SQL Server, and countless other products from their Download Center website. Legacy Update catalogues downloads that have been deleted from Microsoft Download Center since 2012.
