Change value in registry on multiple servers using credentials - powershell

Question

Looking to enable reg key on multiple remote machines.
Attempt 1:
$Servers = Get-Content "C:\PowerShell\TestServers.txt"
$Path = "HKLM:\SYSTEM\CurrentControlSet\Services\"
$Property = "*REG_WORD NAME*"
$Value = "1"
Foreach ($Server in $Servers)
{
Set-ItemProperty -Path $Path -Name $Property -Value $Value
}
Error: Set-ItemProperty : Requested registry access is not allowed.
NOTE: checked effective access, the account being used has FULLControl over the specific hive
Attempt 2:
Created a function, added the get-credential cmdlet
function Set-RemoteRegistryValue {
param (
$ComputerName,
$Path,
$Name,
$Value,
[ValidateNotNull()]
[System.Management.Automation.PSCredential]
[System.Management.Automation.Credential()]
$Credential = [System.Management.Automation.PSCredential]::Empty
)
$null = Invoke-Command -ComputerName $ComputerName -ScriptBlock {
Set-ItemProperty -Path $using:Path -Name $using:Name -Value $using:Value
} -Credential $Credential
}
I am now able to call the function and set the reg key value as desired, but only one machine at a time:
$remoteKeyParams = #{
ComputerName ='name'
Path = "HKLM:\SYSTEM\CurrentControlSet\Services\"
Name = "*keyname*"
Value = "1"
}
Set-RemoteRegistryValue #remoteKeyParams -Credential (Get-Credential)
I have tried putting multiple machines in as a string, and a text file:
[string]$ComputerName = "name","name","name"
ComputerName = c:\temp\testservers.txt
Am I doing something very wrong here?

Confirm you have one server per line and then this is how you should write it.
$Servers = Get-Content "C:\PowerShell\TestServers.txt"
$Path = "HKLM:\SYSTEM\CurrentControlSet\Services\"
$Property = "*REG_WORD NAME*"
$Value = "1"
Invoke-Command -ComputerName $servers -ScriptBlock {
Set-ItemProperty -Path $using:Path -Name $using:Name -Value $using:Value
} -Credential $Credential
When you pass all the server names to Invoke-Command it will run them all asynchronously (up to 32 by default on 5.1)
