I'm using powershell to try and run an installation script remotely on multiple servers, but have become a bit stuck.
Below is what I have so far. Computers.txt contains a list of all the servers I want to run the installation on. These all sit on the same domain. I then map a drive to browse to the share where the script is, and then run the installation script.
$computers = Get-Content -Path c:\temp\Computers.txt
New-PSDrive –Name “S” –PSProvider FileSystem –Root “\\dc1-app01\apps” –Persist
Start-Process -FilePath S:\createfile.bat
I expect I am missing quite a bit in order for this to work? The bat file itself is pretty complex so at the moment I do not want to change this to powershell.
The PC I am running from is also a trusted host on these servers.
Appreciate your input, I'm a powershell newbie
Thanks
I think you're missing the loop that runs through the list (array) of servers:
$VerbosePreference = 'Continue'
$Computers = Get-Content -Path c:\temp\Computers.txt
Foreach ($C in $Computers) {
Write-Verbose "Start batch file as a job on $C"
Invoke-Command -ComputerName $C -ScriptBlock {
New-PSDrive –Name 'S' –PSProvider FileSystem –Root '\\dc1-app01\apps' –Persist
Start-Process -FilePath S:\createfile.bat -Wait
} -AsJob
}
Write-Verbose 'Waiting for all jobs to finish'
Wait-Job
Write-Verbose 'Showing job results:'
Get-Job | Receive-Job
I've also made it a job, so you can run it on multiple servers at the same time.
To even more simplify things, you don't have to map a drive just try this in the ScriptBlock of Invoke-Command:
& '\\dc1-app01\apps\createfile.bat'

The tl;dr: I'm puzzled as to why my script isn't returning back to the deployment machine. Does anyone have an idea why?
I was provided an EXE and a couple arguments to install some software. I'm using PowerShell's Start-Process to run it. The deployment machine is Win Server 2012 domain controller, logged in and being run as domain admin. The test machines are two Windows 10 Pro domained machines. All three have PS 5.1.
Being a silent install, there is no user interaction required. If I run the exact command locally, via RDP, or in a pssession, with just c:\Software.exe /silent /arg2removed, it installs and returns as expected.
The script runs fine up to a point. Nothing happens after Start-Process inside Invoke-Command 's -ScriptBlock. In a separate PowerShell window, I can use Enter-PSSession for each of the two client machines, and Get-Service and Get-Process both show the software's service and background processes, respectively. I can Ctrl+c on the deployment machine and get back to a prompt. No errors are reported at any time.
Here's the Start-Process chunk. I've read the help and it doesn't sound like I'm missing anything that would allow the ScriptBlock to finish. If I prepend Start-Process with Write-Host (like we all do), it echoes the command that would run and I get back to a command prompt on the deployment machine.

-FilePath "C:\${using:SrcExe}" `
-ArgumentList "/SILENT", "/arg2removed" `
-WorkingDirectory C:\ `
-Wait `
-Verbose `
-ErrorAction SilentlyContinue `

Here's most of the script. The only items before Invoke-Command are where I set up $ComputersToInstallOn, enter the credentials (yes I'm sure they're correct), and supply the path to the EXE.

EDIT: Added some requested info.
I'm using the following script to import a .reg file to remote computers. What I need to happen is the following:
Connect to the remote computer and kill a running process if it's running.
Copy a .reg key file from a Network Share location to the remote computer.
Import the copied .reg key to the remote computer's registry.'
Delete the copied .reg key file from the remote computer.
Start the process that was killed at the beginning.
Now I'm relatively new to PowerShell scripting and the script I have is part cannibalized from scripts I've found searching the internet and my PowerShell Cookbook.
What happens when I run the script is that it'll connect to the remote computer and kill the process, but then the script gets hung up, and doesn't do steps 2-5. It's not throwing out any errors either. What am I missing or doing wrong?
Thanks in advance!

I have read the Q/A already available and found no answer for my (maybe too simple?) case.
I have a PS function which:
1) put a local .bat file into a remote machine (target)
2) calls the remote .bat (through invoke-command) passing it a parameter
3) wait for the successful completion of the remote .bat
4) delete the .bat from the target machine
My problem is that everything runs perfectly but...the parameter is not displayed!
The code of the PS script is:
function Run-BatchFile ($computer,$dbn, [string]$batLocation)
{
$sessions = New-PSSession -ComputerName $computer -Credential elsmith
Copy-Item -Path $batLocation -Destination "\\$computer\C$\temp" #copy the file locally on the machine where it will be executed
$batfilename = Split-Path -Path $batLocation -Leaf
Invoke-Command -Session $sessions -ScriptBlock {param($batfilename) & cmd.exe /c "C:\Temp\$batfilename $dbn" } -ArgumentList $batfilename -AsJob
-ArgumentList $batfilename -AsJob
Get-job | Wait-Job
Remove-Item -Path "\\$computer\C$\Temp\$batfilename" -Force
Remove-PSSession -Session $sessions
}
Run-BatchFile SERVERNAME JOHN "C:\Temp\test_remote_called.bat"
The code of the invoked script is just:
set DB=%1
echo Test of %DB% was successful >> c:\temp\output.txt
exit /B
The output is:
Test of was successful
I'm sure there must be a trivial way to solve this problem: am I doing a gross mistake? Am I missing anything?
I'm using the following script to run test.reg on multiple remote systems:
$computers = Get-Content computers.txt
Invoke-Command -ComputerName $computers -ScriptBlock {
regedit /i /s "\\SERVER\C$\RegistryFiles\test.reg"
}
The script doesn't error, but the registry entry doesn't import on any of the systems.
I know test.reg file is a valid registry file because I copied it over, ran it manually, and the registry key imports. I also made sure PowerShell Remoting is enabled on the remote computers.
Any ideas why the registry key isn't importing?
I found the best way not to mess with issues related to server authentication and cut down on complexity just to pass Reg file as parameter to function.
$regFile = #"
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters]
"MaxUserPort"=dword:00005000
"TcpTimedWaitDelay"=dword:0000001e
"#
Invoke-Command -ComputerName computerName -ScriptBlock {param($regFile) $regFile | out-file $env:temp\a.reg;
reg.exe import $env:temp\a.reg } -ArgumentList $regFile
I posted on some PowerShell forums and finally got this working.
I had to 1) move the $newfile variable inside the loop and 2) comment out the $ in the path stored in the $newfile variable.
For reference, the final script looks like this if anyone wants to use it:
$servers = Get-Content servers.txt
$HostedRegFile = "C:\Scripts\RegistryFiles\test.reg"
foreach ($server in $servers)
{
$newfile = "\\$server\c`$\Downloads\RegistryFiles\test.reg"
New-Item -ErrorAction SilentlyContinue -ItemType directory -Path \\$server\C$\Downloads\RegistryFiles
Copy-Item $HostedRegFile -Destination $newfile
Invoke-Command -ComputerName $server -ScriptBlock {
Start-Process -filepath "C:\windows\regedit.exe" -argumentlist "/s C:\Downloads\RegistryFiles\test.reg"
}
}
I am developing a powershell script file which shall execute some disk cleanup without user intervention. The user shall not be able to configure anything.
When I run cleanmgr.exe /d c: sageset:1 a popup window appears to select files/folders to be cleaned(cleanup options).
This will create a registry entry containing the settings with the cleanup options and after this, you can run cleanmgr.exe /sagerun:1 which will actually execute the cleanup.
Is there a way to specify the cleanup options directly with powerhell/command line(without the need to manually select things to be deleted)?
The following Powershell script automates CleanMgr.exe. In this case, it removes temporary files and runs the Update Cleanup extension to purge superseded Service Pack Backup files (Windows 10 now does this automatically via a scheduled task). To automate other extensions, create a "StateFlags0001" property in the corresponding Registry key, as done in the New-ItemProperty lines. You will find the Registry key names in the "VolumeCaches" branch.
As far as being silent, this script attempts to start CleanMgr.exe in a hidden window. However, at some point CleanMgr spawns new processes which are visible and must be waited on separately.
Write-Host 'Clearing CleanMgr.exe automation settings.'
Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches\*' -Name StateFlags0001 -ErrorAction SilentlyContinue | Remove-ItemProperty -Name StateFlags0001 -ErrorAction SilentlyContinue
Write-Host 'Enabling Update Cleanup. This is done automatically in Windows 10 via a scheduled task.'
New-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches\Update Cleanup' -Name StateFlags0001 -Value 2 -PropertyType DWord
Write-Host 'Enabling Temporary Files Cleanup.'
New-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches\Temporary Files' -Name StateFlags0001 -Value 2 -PropertyType DWord
Write-Host 'Starting CleanMgr.exe...'
Start-Process -FilePath CleanMgr.exe -ArgumentList '/sagerun:1' -WindowStyle Hidden -Wait
Write-Host 'Waiting for CleanMgr and DismHost processes. Second wait neccesary as CleanMgr.exe spins off separate processes.'
Get-Process -Name cleanmgr,dismhost -ErrorAction SilentlyContinue | Wait-Process
$UpdateCleanupSuccessful = $false
if (Test-Path $env:SystemRoot\Logs\CBS\DeepClean.log) {
$UpdateCleanupSuccessful = Select-String -Path $env:SystemRoot\Logs\CBS\DeepClean.log -Pattern 'Total size of superseded packages:' -Quiet
}
if ($UpdateCleanupSuccessful) {
Write-Host 'Rebooting to complete CleanMgr.exe Update Cleanup....'
SHUTDOWN.EXE /r /f /t 0 /c 'Rebooting to complete CleanMgr.exe Update Cleanup....'
}
The PowerShell logic provided below is dynamic and ready for use or automation with the sageset options all being selected and no user interaction being required. This was inspired by multiple answers and comments from this post.
Note: I've adjusted for my needs and used successfully without any issues on multiple remote and local Windows 10 systems in particular.

Automate process of Disk Cleanup cleanmgr.exe without user intervention
Creating a Disk Cleanup Handler
You can use cleanmgr /verylowdisk to silently automate all the cleanup steps.
The only solution I found is to manually set the registry values like this:
...
#Set StateFlags0012 setting for each item in Windows 8.1 disk cleanup utility
if (-not (get-itemproperty -path 'HKLM:\Software\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches\Active Setup Temp Folders' -name StateFlags0012 -ErrorAction SilentlyContinue)) {
set-itemproperty -path 'HKLM:\Software\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches\Active Setup Temp Folders' -name StateFlags0012 -type DWORD -Value 2
set-itemproperty -path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches\BranchCache' -name StateFlags0012 -type DWORD -Value 2
set-itemproperty -path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches\Downloaded Program Files' -name StateFlags0012 -type DWORD -Value 2
...
see full example
I ran into the same issue. Researching the possible ways, I have found the following:
http://stealthpuppy.com/cleaning-up-and-reducing-the-size-of-your-master-image/
It shows how to create the sageset registry settings via cmd. You can then use the sagerun:# cmd. I have not tried it via script yet, but have validated that it works...
This script will get all the Volume Caches from the Registry, enable them to be cleaned and run the CLEANMGR.EXE for all caches.
$VolumeCachesRegDir = "hklm:\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches"
$CacheDirItemNames = Get-ItemProperty "$VolumeCachesRegDir\*" | select -ExpandProperty PSChildName
$CacheDirItemNames |
%{
$exists = Get-ItemProperty -Path "$VolumeCachesRegDir\$_" -Name "StateFlags6553" -ErrorAction SilentlyContinue
If (($exists -ne $null) -and ($exists.Length -ne 0))
{
Set-ItemProperty -Path "$VolumeCachesRegDir\$_" -Name StateFlags6553 -Value 2
}
else
{
New-ItemProperty -Path "$VolumeCachesRegDir\$_" -Name StateFlags6553 -Value 0 -PropertyType DWord
}
}

Running CleanMgr.exe in a powershell script or by itself seems to work fine as long as you run it locally with an account that has local admin rights. But try running it remotely via any remote management tool or remote scripting command (Invoke-Command) and it does not run. You might see the process running on the remote system but it doesn't seem to cleanup anything and the process never ends. I would be interested if anyone has been able to get cleanmgr.exe to run remotely without any user interaction. E.G. ConfigMgr Right Click Tools, ConfigMgr App or PKG, Task Scheduler.
