I just saw a post on the Dude where’s my PFE? blog that mentions a new hotfix rollup for for Windows 7 SP1 and W2008 R2 SP1 that:
- Includes lots of patches
- It could, according to the post, shave a minute from the boot time and improve performance for some customers.
- 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.
- 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.
On the the SMB and TCP improvements:
- 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
Two of the hotfixes are not enabled by default:
- KB2581608: Logon scripts take a long time to run in Windows Vista, in Windows Server 2008, in Windows 7 or in Windows Server 2008 R2
- KB2752259: An update that improves the performance of the Printbrm.exe command-line tool in Windows 7 or in Windows Server 2008 R2 is available
According to KB2775511 you can enable them via the registry:
- To enable update KB2581608, configure a REG_DWORD type registry key named RunLogonScriptsNormally under the following path, and set the value to a decimal value of 1:
- To enable update KB2752259, configure a REG_DWORD type registry key named BrmDisableOpc under the following path, and set the value to a decimal value of 1:
You might create a custom GPO template or use a startup script to deploy those settings.
Microsoft’s Michael Griswold has posted an article on how to deploy this rollup using System Center Configuration Manager (SCCM/ConfigMgr).
