One stop shop for avoiding the confusing maze of Microsoft support links to get all the required hot fixes and updates to install Exchange 2010 SP1.

I typically download all the updates and divide them into 3 different ZIP files. 2008-R1.zip for all Server 2008 R1 hot fixes. 2008-R2.zip for all Server 2008 R2 hot fixes. Shared.zip for all the updates that are shared on both platforms. Very handy to keep on a USB thumb drive.

The only updates in the list that are not a deployment blocker by the Exchange 2010 SP1 setup program are the Server 2008 R2 WMI memory leak hot fixes - KB 977357 and 981314. If you monitor your Exchange servers with System Center Operations Manager or anything that repeatedly polls the WMI Win32_Service class, this hot fix is recommended.

From time to time, Microsoft updates the hot fixes. You can see that a few of the hot fixes are already on v2.

The upcoming service packs for Windows and .NET Framework will reduce the importance of these updates and will render the collection obsolete.

Exchange 2010 SP1 has been released to the public here.

Assuming you are installing on a server that has all the Exchange roles enabled, these are the hot fixes you need before you can complete installation:

Updates needed for Server 2008 R2:

KB 977020 - .NET Framework 2.0 hotfix
KB 979099 - AD RMS hotfix
KB 979744 - .NET Framework 2.0 hotfix
KB 979917 - ASP.NET 2.0 hotfix
KB 2282949 - UCMA hotfix - August 2010 - 3.5.6907.210
KB 982867 - .NET Framework 3.5 SP1 hotfix
KB 983440 - ASP.NET 2.0 hotfix rollup
Office 2010 Filter Pack

You might wonder why I am pointing out what technology the hot fix is related to. The reason is, the updates are not made by the Exchange team, and cannot be included in the SP1 download binaries.

I will be providing a list of Server 2008 R1 updates required for Exchange 2010 SP1. Since it is based on the older OS, there are more updates needed than the list above.

If you have trouble finding download links for the above, you can always request them with Hotfixr.

Update: Looks like Technet has the full list now for all operating systems.
