I've pieced together this script that queries multiple remote clients and returns installed software names and versions. However, it seems to miss a few programs and I don't know why. Is there a problem with registry entry it queries. Here is my code:
Invoke-Command -cn SERVER2012, SERVER2012A -ScriptBlock {
Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* |
select DisplayName, DisplayVersion | Format-Table –AutoSize
} | Out-File (join-path ([environment]::GetFolderPath('Desktop')) "GetData.txt")
Don't use the Format-Table cmdlet if you want to use the result later, so it should work without it:
Invoke-Command -cn SERVER2012, SERVER2012A -ScriptBlock {
Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* |
Select-Object DisplayName, DisplayVersion
} | Out-File (join-path ([environment]::GetFolderPath('Desktop')) "GetData.txt")

i got a client who wants to find all of the companys installed programs i wrote a script but i dont want the script show me the same same programs for each comuter every time,i want to see overall installations
$computers = get-adcomputers -filter *
foreach($computer in $computers){
Get-ItemProperty
HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\* |
Select-Object DisplayName, DisplayVersion, Publisher, InstallDate | Format-
Table –AutoSize}
I did not test this, but you can try
$computers = (Get-ADComputer -Filter *).DNSHostName # or use .Name or .CN
$software = Invoke-Command -ComputerName $computers {
Get-ItemProperty -Path 'HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*'
}
$software | Select-Object DisplayName, DisplayVersion, Publisher, InstallDate -Unique |
Format-Table -AutoSize
P.S.1 You need to have admin permissions on all computers to do this
P.S.2 Don't forget there is also HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
Apparently you are running into problems where computers are off-line.
To overcome that, you need to add a loop so you can test if a machine is reachable or not.
$computers = (Get-ADComputer -Filter *).Name # or use .CN
# loop through the collection and (if reachable) get the software list
$result = foreach ($computer in $computers) {
# test if the computer is online
if (Test-Connection -ComputerName $computer -Count 1 -Quiet) {
# output the properties you need to get collected in variable $result
Invoke-Command -ComputerName $computer {
Get-ItemProperty -Path 'HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*'
} | Select-Object DisplayName, DisplayVersion, Publisher, InstallDate
}
else {
Write-Warning "Computer $computer is off-line"
}
}
$software = $result | Select-Object * -Unique
# output to console
$software | Format-Table -AutoSize
# output to CSV file
$software | Export-Csv -Path 'D:\Software.csv' -NoTypeInformation
Good morning,
I have the following script and it works just fine, but instead of hard coding 100 servers I want it to read the servers from a .txt file. Here is my code any help would be great:
[string[]]$servers = 'Server1,Server2,Server3' -split ','
$credential = Get-Credential
Invoke-Command -ComputerName $servers -Credential $credential -ScriptBlock {
Get-ItemProperty 'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*' | Select-Object DisplayName, DisplayVersion, Publisher, InstallDate
} | Format-Table PSComputerName, DisplayName, DisplayVersion, Publisher, InstallDate | Format-Table –AutoSize | Out-File C:\Temp\SoftwareListByServer.txt
$servers = get-content servers.txt
Where servers.txt contains (only) a list of servers one per line.
So I've been over at
https://blogs.technet.microsoft.com/heyscriptingguy/2013/11/15/use-powershell-to-find-installed-software/
trying to use this to get a list of installed programs on a remote machine. I already started the WinRM remotely via PS, and am using the command
Invoke-Command -cn MC-PKS-MCARDH-L -ScriptBlock {
Get-ItemProperty HKLM:\Software\Wow6432Node\* |
select PSPath, PSParentPath, PSChildName
}
The primary use of this is to get the Adobe versions of programs on the client's PC, but for some reason this doesn't return many of the folders. It just returns HP, ESRI, Malwarebytes, and a few others:
PSPath : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\Software\Wow6432Node\ESRI
PSParentPath : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\Software\Wow6432Node
PSChildName : ESRI
PSComputerName : mc-pks-mcardh-l
RunspaceId : 76050648-eec5-4e90-960d-872264a894d4
PSShowComputerName : True
Any reason this is? I tried using the one from the page I linked:
HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*
but Adobe Reader doesn't even show up on that list.
I'm an AD Admin on the domain so why is it not showing all the folders? I'm looking via regedit now on the test machin and theres a folder called Adobe.
I'd recommend using, or at least trying, WMI:
Get-WmiObject -Class Win32_Product | Select-Object -Property Name, Vendor, Version | Format-Table;
You can also specify -ComputerName to query a remote machine.
To list all properties for dev. purposes, try:
Get-WmiObject -Class Win32_Product | Format-List -Property *;
Good luck!
--- ALTERNATIVELY, please try:
[String] $strKey = '';
[String] $strSubKey = '';
[PSCustomObject] $objData = $null;
#( 'HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall', 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall' ) | Foreach-Object {
$strKey = $_;
Get-ChildItem -Path $strKey | Select-Object -ExpandProperty PSChildName | Foreach-Object {
$strSubKey = $_;
$objData = Get-ItemProperty -LiteralPath (Join-Path -Path $strKey -ChildPath $strSubKey) | Select-Object -Property DisplayName, DisplayVersion;
if ( $objData.DisplayName -ne $null ) {
Write-Output -InputObject $objData;
} #if
} #Foreach-Object
} #Foreach-Object
Overall my goal is to get the VNC version for a list of remote computers along with the uninstall GUID so I can remotely uninstall VNC Viewer from certain computers. I have used the Get-WmiObject -Class Win32_Product but that is extremely slow.
I have the following script but in the results it includes the name of the select-object parameter.
$computers = Get-Content -Path "C:\Computers.txt"
$Results = #()
ForEach ($Computer in $Computers) {
$Results += New-Object PSObject -Property #{
"ComputerName" = $Computer
"Name" = Invoke-Command -ComputerName $Computer -ScriptBlock { Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* } `
| Where-Object -FilterScript {$_.DisplayName -like "VNC V*"} | select-object DisplayName
"DisplayVersion" = Invoke-Command -ComputerName $Computer -ScriptBlock { Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* } `
| Where-Object -FilterScript {$_.DisplayName -like "VNC V*"} | select-object DisplayVersion
"ModifyPath" = Invoke-Command -ComputerName $Computer -ScriptBlock { Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* } `
| Where-Object -FilterScript {$_.DisplayName -like "VNC V*"} | select-object ModifyPath
"Vendor" = Invoke-Command -ComputerName $Computer -ScriptBlock { Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* } `
| Where-Object -FilterScript {$_.DisplayName -like "VNC V*"} | select-object Publisher
}
}
$Results | Select-Object ComputerName,Name,DisplayVersion,ModifyPath,Vendor | Sort-Object ComputerName | Export-Csv C:\VNC.csv -notype ;
My results look like this:
ComputerName : ComputerName
Name : #{DisplayName=VNC Viewer 5.2.3}
DisplayVersion : #{DisplayVersion=5.2.3}
ModifyPath : #{ModifyPath=MsiExec.exe /I{18B1E36F-0DA3-4FDA-BC57-DD815B0DF3B2}}
Vendor : #{Publisher=RealVNC Ltd}
I would want it to look like this:
ComputerName : ComputerName
Name : VNC Viewer 5.2.3
DisplayVersion : 5.2.3
ModifyPath : MsiExec.exe /I{18B1E36F-0DA3-4FDA-BC57-DD815B0DF3B2}
Vendor : RealVNC Ltd
Is this possible or am I going about this script entirely wrong? I haven't figured out a way to run this Invoke-Command for multiple parameters and still output the results in individual columns any other way.
This script works but takes forever for 100's of computers:
if (Test-Path C:\VNCInstalled.csv) {Remove-Item C:\VNCInstalled.csv}
if (Test-Path C:\Computers.txt) {Remove-Item C:\Computers.txt}
$DirSearcher = New-Object System.DirectoryServices.DirectorySearcher([adsi]'')
$DirSearcher.Filter = '(&(objectClass=Computer)(!(cn=*esx*)) (!(cn=*slng*)) (!(cn=*dcen*)) )'
$DirSearcher.FindAll().GetEnumerator() | sort-object { $_.Properties.name } `
| ForEach-Object { $_.Properties.name }`
| Out-File -FilePath C:\Computers.txt
Get-Content -Path c:\Computers.txt `
| ForEach-Object {Get-WmiObject -Class Win32_Product -ComputerName $_} `
| Where-Object -FilterScript {$_.Name -like "VNC V*"} `
| select-object #{Name="ComputerName";Expression={$_.PSComputerName}},
Name,
#{Name="InstallLocation";Expression={$_.PackageCache}},
Vendor,
Version,
#{Name="GUID";Expression={$_.IdentifyingNumber}} `
| Sort-Object ComputerName `
| Export-CSV -path c:\VNCInstalled.csv -notype
Change all of your Select-Object commands to Select-Object
-ExpandProperty PropertyName, to discard the property name / column header.
This is the answer I gave three years ago and I think it was really a poor answer. Let me do a better job now.
Why your current code is slow
Your current code enumerates all machines from AD and puts them in a file called Computers.txt. Simple, and you do it fine.
Next up, your code performs this operation:
Get-Content -Path c:\Computers.txt |
ForEach-Object {Get-WmiObject -Class Win32_Product -ComputerName $_} `
| Where-Object -FilterScript {$_.Name -like "VNC V*"} [...]
This can be summarized as 'For each computer, request the full Win32_product table, and then after that, filter down to apps named VNC.' This is HUGELY performance impacting and for a few reasons.
Even on a fast modern computer, querying Win32_Product will take 30 seconds or more, because it returns every application installed. (on a new VM for me it took more than a minute with just a handful of apps installed!)
Querying Win32_Product also has this fun quirk which makes it take even longer, quoted from MSDN Documentation on the Win32_Product Class
Warning Win32_Product is not query optimized. Queries such as "select * from Win32_Product where (name like 'Sniffer%')" require WMI to use the MSI provider to enumerate all of the installed products and then parse the full list sequentially to handle the “where” clause. This process also initiates a consistency check of packages installed, verifying and repairing the install. With an account with only user privileges, as the user account may not have access to quite a few locations, may cause delay in application launch and an event 11708 stating an installation failure. For more information, see KB Article 794524.
So to summarize, querying Win32_Product is slow, AND it also triggers a consistency chceck on every app, AND we also have this query written to retrieve every single app before filtering. These add up to a process which probably takes ~3 minutes per pc, and will operate serially (one after the other) and take forever.
How to fix it
Software info can be retrieved reliably in two places:
If you have SCCM/ConfigMgr installed on your devices, it adds the Win32_AddRemoveProgram WMI Class you can query, which is a super fast version of Win32_Product
If not, we can always retrieve info from the registry.
Here's a short snippet to get applications like VLC installed on a computer (I don't have VNC like you, so I'm making due)
Get-ItemProperty HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\* | Where-object DisplayName -like "VLC*" |Select-Object DisplayName, DisplayVersion, Publisher, InstallDate,UninstallString
DisplayName : VLC media player
DisplayVersion : 3.0.8
Publisher : VideoLAN
InstallDate :
UninstallString : "C:\Program Files (x86)\VideoLAN\VLC\uninstall.exe"
This operation is much faster, only 400 MS or so. Sadly we cannot get much faster using the registry as it has a very weird PowerShell provider that doesn't implement the -Filter parameter, so we do have to retrieve all programs and then filter to our desired choice.
Updating your script to use this function instead
I took the liberty of rewriting your script to use this approach, and restructured it a bit for better readability.
$results = New-object System.Collections.ArrayList
$computers = Get-Content -Path c:\Computers.txt
foreach ($computer in $computers){
#get VNC entries from remote computers registry
$VNCKeys = Invoke-Command -ComputerName $computer -ScriptBlock {
Get-ItemProperty HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\* |
Where-object DisplayName -like "VNC V*" |
Select-Object DisplayName, DisplayVersion, Publisher, UninstallString, #{Name=‘ComputerName‘;Expression={$computer}}
}#end of remote command
if ($VNCKeys -ne $null){
forEach($VNCKey in $VNCKeys){
[void]$results.Add($VNCKey)
}
}
}
$results | Sort-Object ComputerName | Export-CSV -path c:\VNCInstalled.csv -NoTypeInformation
I am trying to run this simple script to get the services and the accounts that are running them. My problem is that the data looks correct in the report but the server name does not change in the report. Here is the code.
$servers = get-content C:\temp\servers.txt
foreach ($server in $servers)
{
Get-WmiObject win32_service | Select-Object -Property SystemName, DisplayName, startname | format-list -GroupBy startname | Out-File c:\temp\results.txt
}
This will work.
$servers = get-content C:\temp\servers.txt
foreach ($server in $servers)
{
Get-WmiObject win32_service -Computername $server | Select-Object -Property SystemName, DisplayName, startname | format-list -GroupBy startname | Out-File -append c:\temp\results.txt
}
You can also use the following but note SystemName is not a property of Win32_Service. To troubleshoot this, try using Get-Service | Select -first 1 | Get-Member will display the available attributes (sorry if this is the wrong term) with the important one being MachineName thus replace SystemName for MachineName and you'll get the desired results. Look up Hey Scripting Guy articles for further information. For example, this page
gc .\Servers.txt | foreach {get-service -ComputerName $_ | `
Select-Object -Property MachineName, DisplayName, startname | `
format-list -GroupBy startname | Out-File -append c:\temp\results.txt}
Note, I'm using the backtick ` to make the command readable, paste into the Powershell ISE to save/run the script or just paste the lines into the console and press enter twice to run the multi-line script.
