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:

- 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.

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.
