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

Instead of updating my previous post which covers only Exchange 2007, I decided to create a new post which covers both versions.

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?

# Store header in variable
$headerLine =
@"

Server Name,Rollup Update Description,Installed Date,ExSetup File Version
"@

# Write header to file
$headerLine | Out-File .\results.csv -Encoding ASCII -Append

function getRU()
{
# Set server to connect to
	$Server = "$_".ToUpper()


# Check if server is running Exchange 2007 or Exchange 2010

	$ExchVer = (Get-ExchangeServer $Server | ForEach {$_.AdminDisplayVersion.Major})

# Set appropriate base path to read Registry
# Exit function if server is not running Exchange 2007 or Exchange 2010
	if ($ExchVer -eq "8" -or $ExchVer -eq "14")
		{
			switch ($ExchVer)
			{
			 "14"	{
			 			$REG_KEY = "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Installer\\UserData\\S-1-5-18\\Products\\AE1D439464EB1B8488741FFA028E291C\\Patches"
						$Reg_ExSetup = "SOFTWARE\\Microsoft\\ExchangeServer\\v14\\Setup"

						$Reg_ExSetup = "SOFTWARE\\Microsoft\\Exchange\\Setup"
			 		}
			}
		}
	else
		{return}

	$instDate = [array] ($regkey | %{$reg.OpenSubKey($_).getvalue($VALUE2)})

# Loop Through array variables and output to a file
	$countmembers = 0

	if ($regkey -ne $null)

		$countmembers++

	else
	{
		$server+",No Rollup Updates are installed,,"+$exsetupver | Out-File .\results.csv -Encoding ASCII -Append
	}
}

# Get Exchange 2007 servers and write Rollup Updates to results file
$Servers = (Get-ExchangeServer | Where-Object {($_.AdminDisplayVersion -match "8" -OR $_.AdminDisplayVersion -match "14") -AND $_.ServerRole -ne "ProvisionedServer" -and $_.ServerRole -ne "Edge"} | ForEach {$_.Name})
$Servers | ForEach {getRU}
