Slow Boot Slow Login (SBSL) Hotfix Rollup for Windows 7 and Server 2008 R2 Available Today!



AskPFEPlat is in the process of a transformation to the new Core Infrastructure and Security TechCommunity, and will be moving by the end of March 2019 to our new home at (hosted at Please bear with us while we are still under construction!

We will continue bringing you the same great content, from the same great contributors, on our new platform. Until then, you can access our new content on either as you do today, or at our new site Please feel free to update your bookmarks accordingly!

Why are we doing this? Simple really; we are looking to expand our team internally in order to provide you even more great content, as well as take on a more proactive role in the future with our readers (more to come on that later)! Since our team encompasses many more roles than Premier Field Engineers these days, we felt it was also time we reflected that initial expansion.

If you have never visited the TechCommunity site, it can be found at On the TechCommunity site, you will find numerous technical communities across many topics, which include discussion areas, along with blog content.

NOTE: In addition to the AskPFEPlat-to-Core Infrastructure and Security transformation, Premier Field Engineers from all technology areas will be working together to expand the TechCommunity site even further, joining together in the technology agnostic Premier Field Engineering TechCommunity (along with Core Infrastructure and Security), which can be found at!

As always, thank you for continuing to read the Core Infrastructure and Security (AskPFEPlat) blog, and we look forward to providing you more great content well into the future!


Hey y’all, Mark here with some great news. 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.

Few things I want to point out. First, this applies to both Windows 7 SP1 clients and Server 2008 R2 SP1 as seen here. This is how you can take full advantage of the networking updates.

“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.”

Second, use Xperf to baseline before and after the update is applied. We’ve been talking about Xperf forever here. Use this as an opportunity to really be the hero. Show the improvement that can affect EVERYONE in the enterprise daily. Multiply that by how many work days there are and that is a nice thing to hang your hat on. Not a bad day at the office.

Post in the comments how much time you saved. We love to hear before and after stories.

Finally, as the article states, “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.” That does include putting this in your test lab first right? Right? Right!?

Thanks to all the PFEs, CTS and Devs that help collaborate to make this happen. Specifically the Dude Jeff Stokes, BenChrist, and A. Conner for driving this bus.

Update 3/13/13- We received a few questions as to why 2775511 resides exclusively on the Windows Catalog vs WSUS. Windows Catalog distribution allows administrators to distribute the rollup in either WSUS or System Center throughout the enterprise. This allows for increased coverage by companies that are normally refrained from downloading adhoc hotfixes. 


 Update 3/14/13- Fellow SCCM PFE Michael Griswold has a blog post about importing this into SCCM. If you are having issues take a look at
