I'm working on a script that cleanup old user account and some data from computers. I would like to run the script on 5 computers at one time from the attached list of PCs. Is it possible? If so, how can it be done?

 [CmdletBinding()] Param( [Parameter(Mandatory=$true)] [string]$host_path = 'Host path' ) $computer = Get-Content "$host_path" foreach ($computer in $computer){ Invoke-Command -ComputerName $computer -ScriptBlock { Get-WMIObject -class Win32_UserProfile | Where {(!$_.Special) -and ($_.ConvertToDateTime($_.LastUseTime) -lt (Get-Date).AddDays(-30))}| Remove-WmiObject } Invoke-Command -ComputerName $computer -ScriptBlock { Remove-Item -Path C:\Windows\ccmcache\* -Confirm:$false -Force -Recurse -Debug } Invoke-Command -ComputerName $computer -ScriptBlock { Remove-Item -Path C:\ProgramData\1E\NomadBranch\* -Confirm:$false -Force -Recurse -Debug } }

You can pass multiple computer names to Invoke-Command at once to achieve this:

[CmdletBinding()] Param( [Parameter(Mandatory=$true)] [string]$host_path = 'Host path' ) $computerNames = Get-Content $host_path Invoke-Command -ComputerName $computerNames -ScriptBlock { Get-WMIObject -class Win32_UserProfile | Where {(!$_.Special) -and ($_.ConvertToDateTime($_.LastUseTime) -lt (Get-Date).AddDays(-30))}| Remove-WmiObject Remove-Item -Path C:\Windows\ccmcache\* -Confirm:$false -Force -Recurse -Debug Remove-Item -Path C:\ProgramData\1E\NomadBranch\* -Confirm:$false -Force -Recurse -Debug }

If you want to "chunk" the list of computer names into batches on N machines at a time, you can do it like this:

$computerNames = Get-Content $host_path $batchSize = 5 while($computerNames.Count -gt 0){ # Pull the first N names from the list $nextBatch = @($computerNames |Select -First $batchSize) # Then overwrite the list with any elements _after_ the first N names $computerNames = @($computerNames |Select -Skip $batchSize) Write-Host "Executing remote command against $($nextBatch.Count) computers: [$($nextBatch.ForEach({"'$_'"}) -join ', ')]" # Invoke remoting command against the batch of computer names Invoke-Command -ComputerName $nextBatch -ScriptBlock { Get-WMIObject -class Win32_UserProfile | Where {(!$_.Special) -and ($_.ConvertToDateTime($_.LastUseTime) -lt (Get-Date).AddDays(-30))}| Remove-WmiObject Remove-Item -Path C:\Windows\ccmcache\* -Confirm:$false -Force -Recurse -Debug Remove-Item -Path C:\ProgramData\1E\NomadBranch\* -Confirm:$false -Force -Recurse -Debug } }

Hi, What if I want to do it but for 5 computers taken from the list at one time then wait and make it for another 5 computers?
@pawelek4318 Just pull 5 computers at a time from the initial array. I've updated the answer with an example
It works like expected, thank you very much for the help :D

If you are using PowerShell 7.x, you can do the following.

[CmdletBinding()] Param( [Parameter(Mandatory=$true)] [string]$host_path = 'Host path' ) # The default value for ThrottleLimit is 5, but I put it here to show syntax. # Throttle is the number of concurrent runspaces to use. (ex: do 5 objects at a time) Get-Content $host_path | Foreach-Object -ThrottleLimit 5 -Parallel -ScriptBlock { Invoke-Command -ComputerName $_ -ScriptBlock { Get-WMIObject -class Win32_UserProfile | Where-Object {(!$_.Special) -and ($_.ConvertToDateTime($_.LastUseTime) -lt (Get-Date).AddDays(-30))}| Remove-WmiObject Remove-Item -Path C:\Windows\ccmcache\* -Confirm:$false -Force -Recurse -Debug Remove-Item -Path C:\ProgramData\1E\NomadBranch\* -Confirm:$false -Force -Recurse -Debug } }

This will run X loops at a time, X being your -ThrottleLimit value, which defaults to 5.

Again, this is only available in PowerShell 7, and not backwards compatible with Windows PowerShell.
