I first came across this code on Jeff Guillet’s blog here, which the source came from Paul Falherty’s blog initially, back in 2009 for Exchange 2007. Mark E. Smith also had code with a slight modification for Exchange 2010 posted here.
Today I decided to merge these to work with Exchange 2007, 2010, and 2013 into one script.
The change was pretty minor, just had to change the registry path used. Exchange 2010 and 2013 use the same registry path to store updates, but 2007 uses a different one.

Thanks Nick, didn’t notice this but I’ve now fixed it so now HTML codes and formatting should be in the script.
I always post a URL link directly to the latest version of the script on my web server, so go there for the best source code.

I know I’m responding to an old post, but for some reason your script takes much longer to run than the script you modified. Jeff’s script takes but 5-10 seconds to run for my environment, but your script takes 1-2 min. Any ideas why? I can’t spot anything that would cause this.

Nevermind, I have figured it out! In line #53 above, there is a typo. You are missing the $ in front of Installed = “”.
This was causing the script to error out multiple times as it iterates through each subkey value being returned. This was being hidden by the error action being silent.

Oops, thanks! Fixed

Hi, Your script has worked well before, but it fails now to recognize Exchange 2010 SP3 RollUp 10, the last RU for Exchange 2010. SP3 RU10 is Version 14.3 Build 248.2.
This seems to be a common problem I’ve been finding when trying to check the version. The EMC does not report it, it still reports the base SP3 build of 123.4. As does powershell command I’ve used before also fails to report it:
[PS] C:\>Get-ExchangeServer | Format-List Name, Edition, AdminDisplayVersion
Name : EX-CH001
Edition : Standard
AdminDisplayVersion : Version 14.3 (Build 123.4)
I found the command “gcm exsetup | fl” provides the correct build # of the Rolup in the file info of EXSetup.exe:
[PS] C:\>gcm exsetup | fl
Name : ExSetup.exe
CommandType : Application
Definition : D:\Exchange\2010\bin\ExSetup.exe
Extension : .exe
Path : D:\Exchange\2010\bin\ExSetup.exe
FileVersionInfo : File: D:\Exchange\2010\bin\ExSetup.exe
InternalName: ExSetup.exe
OriginalFilename: ExSetup.exe
FileVersion: 14.03.0248.002

I also found another script that reports the Rollup 10 as installed at: https://onedrive.live.com/prev?cid=14adc5cf1e0cbccf&id=14ADC5CF1E0CBCCF%21732&v=TextFileEditor
It puts the results in a CSV.
