Exchange Server 2010 Service Pack 1 requires a number of hotfixes to be installed. These are listed in Exchange 2010 Prerequisites in Exchange 2010 documentation and in the Exchange 2010 SP1 FAQ and Known Issues post on the Exchange team blog.
While preparing a server for SP1, I erroneously kept trying to install the hotfixes on the Hyper-V host sytem, which has Windows 2008 R2 (instead of the VM running Windows Server 2008 SP2). Obviously, none of the hotfixes I downloaded for Windows 2008 SP2 would apply, and the hotfix installer kept informing me about the same.

To get a list of hotfixes installed on your system, you can use the Get-Hotfix cmdlet available in Windows PowerShell v2. If you simply use the Get-Hotfix cmdlet without any parameters, it retrieves a list of all hotfixes. The default output includes the following properties:
- Source (server)
- Description (Hotfix | Update | Security Update | Service Pack)
- HotFixID (for example, KB973136)
- InstalledBy (user)
- InstalledOn (date/time installed)
You can also use the Id parameter to specify one or more hotfixes:
Get-Hotfix -Id kb979744
To determine whether the hotfixes required for Exchange 2010 SP1 (on Windows 2008 SP2) are installed on a server, use the following command:
Get-Hotfix kb973136,kb977592,kb977624,kb979099,kb979744,kb982867,kb979917
On the first run, I found only two of the required hotfixes were installed:
Source Description HotFixID InstalledBy InstalledOn
—— ———– ——– ———– ———–
EX2 Hotfix KB977624 E14LABS\Administr… 8/27/2010 10:29:01 AM
EX2 Update KB979099 E14LABS\Administr… 8/27/2010 10:29:01 AM
After I installed the missing hotfixes, I ran the cmdlet again. The result:
Source Description HotFixID InstalledBy InstalledOn
—— ———– ——– ———– ———–
EX2 Hotfix KB973136 E14LABS\Administr… 9/19/2010 12:27:04 AM
EX2 Hotfix KB977592 E14LABS\Administr… 9/19/2010 12:29:06 AM

EX2 Hotfix KB979744 E14LABS\Administr… 9/19/2010 12:30:34 AM
EX2 Hotfix KB979917 E14LABS\Administr… 9/19/2010 12:37:11 AM
EX2 Hotfix KB982867 E14LABS\Administr… 9/19/2010 12:35:45 AM
High on my wishlist: the -DownloadAndInstallMissingHotfixes switch for this cmdlet!

I love your wishlist request. That would be too simple and too much like Debian Linux for it to EVER be done by Microsoft. I can not believe how much time I’ve wasted trying to get Microsoft server software installed.
Thanks for the tip.
Aaron, I can’t believe how much time I’ve wasted trying to get Linux servers installed too, not to mention MS stuff. Missing libraries, dependencies on newer versions of libraries that aren’t installed, conflicts with versions for things like eAccelerator, JPEG support, PHP, etc. And don’t even get me started on differences in installations of packaged apps vs their source install versions (ClamAV, I’m looking specifically at you).
But I guess in a perfect world we’d never have to learn anything about this stuff and merely type or click *install*.
