A massive Slow Boot Slow Login (SBSL) hotfix rollup for enterprises that includes 90 post Windows 7/2008 R2 hotfixes is available for download. The hotfixes focus on performance (Hooray!) and stability (Hooray again!). There are improvements to the DFSN client, Folder Redirection, Offline Files and Folders, WMI, and SMB client to name a few. There also improvements to Group Policy which gets blamed for pretty much everything when I'm doing a WDRAP. You can read the full list of improvements here.

"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."

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.

This is a collection of the various updates we kept (we being PFEs who do WDRAP in particular) and Yong Rhee published for us, like blogs.technet.com/b/yongrhee/archive/2012/02/19/list-of-performance-hotfixes-post-sp1-for-windows-7-sp1.aspx.

This is now a Rollup for Enterprises. It is not in Windows Update, but is in the Catalog here:

There are a couple caveats around roaming profiles and some other issues, regkeys and so forth, so test it. But most customers should see a minute or more reduced from boot, and a more peppy system, as a result. (Source)

[mrbios]

EDIT: oh and just to really make it feel like it's rubbing it in.....the KB Article ID is the same as one of my IDs here at work! WHAT THE ****!

[timbo343]

Would anyone be able to put the files somewhere please, having trouble downloading them.

[Arthur]

having trouble downloading them.

I must admit, I had probs importing the updates into WSUS. I tried an hour later and it worked correctly. It could be Microsoft's servers are being hammered by Edugeekers tut tut

[timbo343]

I just couldnt download them, they kept failing.

Working now :S

[Boon72]

would this work for a 2008 server & W7 environment?

[Arthur]

would this work for a 2008 server & W7 environment?

Only 2008 R2 and Windows 7.

This needs to be a 'sticky'.

I note that unlike most Update Rollups and before them Service Packs, almost all the included component updates move machines over to the LDR branch. I think MS has scared people in the past with dire warning about 'only apply if affected by the issue' and this is the first formal step I have seen that indicates the new world order of patch early patch often.

Update Rollups are the future.

Does anyone know what the caveats around roaming profiles are? The source linked above has been edited and no longer mentions it, and I can't see owt in the kb article either.

However: exciting

[psydii]

Roaming Profiles don't work well with wired 802.1x if you transition between machine and user authentication.
Roaming Profile may not work properly with 802.1x network
