How do I check Update Rollup version on Exchange 20xx Server?

Posted by in Exchange 2007, Exchange 2010, Exchange Management Shell, Exchange Server, PowerShell

UPDATED: Feb 26, 2014, updated script to accommodate Exchange 2013

Now that Update Rollup for Exchange Server 2010 is available, I have updated my previous script to check for Update Rollup versions on both Exchange Server 2007 and Exchange Server 2010. No need to have two versions of script. Just download this one!

Here’s what has changed between versions:

  • Product GUID has changed to AE1D439464EB1B8488741FFA028E291C (Exchange 2010) from 461C2B4266EDEF444B864AD6D9E5B613 (Exchange 2007).
  • Exchange writes installation information to HKLM\SOFTWARE\Microsoft\ExchangeServer\v14\Setup instead of “HKLM\SOFTWARE\Microsoft\Exchange\Setup”

The script below will do the work for you so you don’t need to remember what I just said above. Isn’t that what script is for?
