Some of the hotfixes would have been rolled up in a Windows update or service pack. Given that the Exchange team released SP1 earlier than what was planned and announced earlier, it did not align with some of the work with the Windows platform. As a result, some hotfixes are available from MSDN/Connect, and some require that you request them online using the links in the corresponding KBs. All these updates may become available on the Download Center, and also through Windows Update.
These hotfixes have been tested extensively as part of Exchange 2010 SP1 deployments within Microsoft and by our TAP customers. They are fully supported by Microsoft.
The TechNet article Exchange 2010 Prerequisites is updated with the hotfixes and install the prerequisites required for your server version (the hotfixes are linked to in the above table).
You can use the Install the Windows Server 2008 SP2 operating system prerequisites on a Windows 2008 R2 server. Only you have to run the following powershell command: Import-Module ServerManager
Installed Exchange 2010 SP1 on a Windows 2008 R2 Server with problems. I feels that the MMC is faster. Tomorrow upgrading a DAG/NLB cluster to Exchange 2010 SP1.
