Getting the software unistall DisplayName from registry

We are doing software housekeeping on our Windows 2003 servers in preparation to migrate to higher release
I need to retrieve the installed software from these boxes.

Instead of the if statement below, I would like to use an array as follows. Thank you in advance.
$OmitSoft = @("", "\(KB", "McAfee ", "HP ", "Service Pack", "IBM ", "Internet Explorer", .......,"VMware ")

$UninstallKey = "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall"

    ForEach ($key in $SubKeys) {
        $thisKey = $UninstallKey+"\\"+$key
        $thisSubKey = $reg.OpenSubKey($thisKey)
        $DisplayName = $($thisSubKey.GetValue("DisplayName")).Trim()

        if (-not ($DisplayName -match "\(KB") -and ($DisplayName -ne "") -and ($DisplayName -match "McAfee") -and `
                 ($DisplayName -notmatch "HP ") -and ($DisplayName -notmatch "Internet Explorer")) {
           
            $ObjData = New-Object PsObject -Property  ([ordered]@{
               "ServerName"  = $ComputerName
               "Virtual"     = $Virtual
               "OSName"      = $DisplayName
               "OSVersion"   = $($thisSubKey.GetValue("DisplayVersion"))
               "Description" = $($thisSubKey.GetValue("Publisher"))
            })

            Export-Csv -InputObject $ObjData -NoTypeInformation $CsvFile -Force -Append
        }
    }
