Hi,

I am using this script to get the list of all softwares installed on a
computer.

New-PSDrive -Name Uninstall -PSProvider Registry -Root
HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

Get-ChildItem -Path Uninstall: | ForEach-Object -Process {
$_.GetValue("DisplayName") } | sort-object DisplayName

While this works fine for a local computer, how would I extend this script
to work on a remote computer and that also in a loop for hundreds of
computers.

Is it possible to connect to a remote computer and then create the drive,
extract the data and then delete the drive and then move on to the next
computer.

Thanks

You could use the .NET provider:

function Get-Apps {
Param([string]$server)
$regKey =
[Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey([Microsoft.Win32.RegistryHive]::LocalMachine,
$Server)
$regKey =
$regKey.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall")
$regKey.GetSubKeyNames()
# $regKey | gm # uncomment for methods\properties you can use.
}

Of course you could pretty up the code a bit and get different information,
but this is basically it.
You could also add begin/process/end to process piped information.

function Get-Apps {
Param([string]$server)
Begin{
function CheckRegKey{
param([string]$srv)
$regKey =
[Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey([Microsoft.Win32.RegistryHive]::LocalMachine,
$Srv)
$regKey =
$regKey.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall")
$regKey.GetSubKeyNames()
# $regKey | gm # uncomment for methods\properties you can use.
}
}
Process{
if($_){
CheckRegKey $_
}
}
End{
if($Server){
CheckRegKey $server
}
}
}


p.s. Sorry for the formatting... Blasted News Readers!!!

Hi Brandon,

Thanks for the reply. Could you please help on how to invoke this function
from a ps1 file. and how would you write all the information to a file for
each server that is passed to the function.

Thanks

Terminator.

You have two options...

1 - You could copy the function to a text file. Name it anything.ps1.
- You can then . source the file (this puts the function in your current
context.):
PS> . \PathtoScript\anything.ps1
When its in your context you can just call the function directly:
PS> Get-Apps ServerName
or
PS> $slist | Get-Apps

2 - Remove the function Get-Apps { and ending }.
- Save the text file as Get-Apps.ps1
PS> PathtoScript\Get-Apps.ps1 ServerName
or
PS> $slist | PathtoScript\Get-Apps.ps1
