Hotfix Rollup for Windows 7 SP1 and Windows 2008 R2 SP1

On March 13, 2013 Microsoft released KB 2775511. They refer to this as “an enterprise hotfix rollup” for Windows 7 SP1 and Windows 2008 R2 SP1. This rollup contains 90 hotfixes that have been issues since the release of SP1 for Windows 7/Windows 2008 R2.

The chatter on this release is that a lot of work went into this rollup, and that you definitely want to be looking at this for your customers and your own systems. Microsoft says that this hotfix rollup improves the overall performance and system reliability of Windows 7/Windows 2008 R2 SP1 systems.

One small example: I installed it on my own Windows 7 workstation and saw a dramatic improvement in boot time.

Now, for whatever reason, you will NOT find this hotfix rollup on Microsoft Update (MU) or Windows Update (WU) or on WSUS. That’s correct – you will NOT find it there. Instead, you will find it on the Microsoft Update Catalog download site. I know … I’m with you on this one as I didn’t know about this site myself.

But lets stop gabbing and get to downloading and installing the rollup!

  1. You can read the details about this rollup here: KB 2775511 
  2. Or go straight to the Microsoft Update Catalog site
  3. In the Search box, enter 2775511 and click Search
  4. The list of available files are displayed. There are separate versions of this hotfix rollup for Windows 7/x86, Windows 7/x64, Windows 2008 R2 x64, and Windows 2008 R2 Itanium.
  5. Click on the Add button for those versions you want.

  7. For each version, a folder is created with two files in it — a .exe file and a .msu file.
    Double click on the appropriate .msu file to install the hotfix.
  8. Install and reboot your system. That’s it!

Now, for those who like to do performance measurement, there’s a tool called XPerf you may want to take a look at. There’s a nice blog post on using XPerf to measure Slow Boot Slow Logon (SBSL) scenarios
