Introduction

This article describes a hotfix rollup for Windows 7 Service Pack 1 (SP1)-based and Windows Server 2008 R2 SP1-based computers. This hotfix rollup contains 90 hotfixes that were released after the release of SP1 for Windows 7 and Windows Server 2008 R2. These hotfixes improve the overall performance and system reliability of Windows 7 SP1-based and Windows Server 2008 R2 SP1-based computers. We recommend that you apply this hotfix rollup as part of your regular maintenance routine and build processes for Windows 7 and Windows Server 2008 R2 computers.

Note This hotfix rollup primarily addresses the issues that occur on domain-joined client computers and servers. Therefore, this hotfix rollup is available only from the Microsoft Update Catalog. You can also install this hotfix rollup on computers that are running Windows 7 SP1 in nonenterprise environments. After you install the hotfix rollup, the performance of the computers may be improved.

This hotfix rollup includes the following improvements:
  • Improves the Windows Client Remote File System components. These components include the following:
    • Web-based Distributed Authoring and Versioning (WebDAV)
    • DFSN client
    • Folder Redirection
    • Offline Files and Folders (CSC)
    • SMB client
    • Redirected Drive Buffering Subsystem (RDB)
    • Multiple UNC Provider (MUP)
  • Improves the SMB Service and TCP protocol components. These improvements work together with other improvements to help improve the overall networking performance on Windows 7 SP1-based and Windows Server 2008 R2 SP1-based computers.

    Notes
    • To take full advantage of this improvement for Windows 7 clients that log on to Windows Server 2008 R2 servers, install this rollup update on Windows 7 clients. Additionally, install this rollup update on the Windows Server 2008 R2 servers that clients authenticate and retrieve user profiles, policies and script data from during the startup and logon process. You can update your environment by installing this hotfix rollup on both clients and servers in no particular order.
    • Network improvements can be installed on the client or server. You may not notice any changes in performance until this update is installed on both client and server computers.
  • Improves the processing of Group Policies and Group Policy preferences. The performance of computers is improved after you install this rollup update on Windows 7-based computers that have several Group Policy preferences configured. Additionally, the network load and the domain controller usage may be reduced. We recommend that you install this hotfix rollup on every Windows 7 computer that has Group Policy preferences configured.
  • Improves the Windows Management Instrumentation (WMI) components to reduce the CPU usage and to improve the repository verification performance.
This rollup update contains the latest version of Windows system files that are updated after the SP1 release. The following hotfixes are included in this rollup update:
