One thought on “Script required for to fetch Installed applications on Windows Server”

1. Hello there,
   Please try to use the following code. It performs additional registry check. I’m using it on 2008R2, 2012R2 and have no missing entries.
   On the last line, change the $HOSTNAME to a list of computers or single remote host. (The script is using PSRemoting, so be sure that the remote hosts have PSRemoting enabled).

   $InstSoftBlock = {
   $AllinstallKeys = @()
   $UninstallKeys = Get-ItemProperty “HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*”
   Foreach ($key in $UninstallKeys)
   {
   $InstSoftObject1 = New-Object PSObject
   Add-Member -inputObject $InstSoftObject1 -memberType NoteProperty -name “DISPLAYNAME” -value $key.DisplayName
   Add-Member -inputObject $InstSoftObject1 -memberType NoteProperty -name “DISPLAYVERSION” -value $key.DisplayVersion
   Add-Member -inputObject $InstSoftObject1 -memberType NoteProperty -name “KEY” -value $key.PSChildName
   $AllinstallKeys += $InstSoftObject1
   }
   #Additional registry check
   If ($UninstallKeys2 = Get-ItemProperty “HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*” -ErrorAction SilentlyContinue)
   {
   Foreach ($key2 in $UninstallKeys2)
   {
   $InstSoftObject2 = New-Object PSObject
   Add-Member -inputObject $InstSoftObject2 -memberType NoteProperty -name “DISPLAYNAME” -value $key2.DisplayName
   Add-Member -inputObject $InstSoftObject2 -memberType NoteProperty -name “DISPLAYVERSION” -value $key2.DisplayVersion
   Add-Member -inputObject $InstSoftObject2 -memberType NoteProperty -name “KEY” -value $key2.PSChildName
   $AllinstallKeys += $InstSoftObject2
   }
   }
   $AllinstallKeys
   }
   #Establish remote connection
   $InstSoftObj = Invoke-Command -ComputerName $HOSTNAME -scriptblock $InstSoftBlock
