Remoting and Automation

PowerShell Remoting

PSRemoting runs commands on remote machines using WinRM:

Invoke-Command -ComputerName srv01 -ScriptBlock { Get-Service Spooler }
Invoke-Command -ComputerName srv01,srv02 -ScriptBlock { Get-Process -Name winlogon }

Enable it on targets with Enable-PSRemoting -Force from an admin shell.

Run Jobs in Background

Start-Job -ScriptBlock { 1..10 | ForEach-Object { $_ } }
Get-Job
Receive-Job

Jobs keep output and run independently of the console.

Scheduled Tasks

Register-ScheduledTask ties scripts to schedules:

$action = New-ScheduledTaskAction -Execute 'pwsh' -Argument '-File C:scriptsackup.ps1'
Register-ScheduledTask 'Nightly Backup' -Action $action -Trigger New-ScheduledTaskTrigger -Daily -At 2am

Secrets and Safety

• Never embed passwords; use Secret Management or prompts.
• Validate inputs and use -ErrorAction Stop.
• Log outputs and run tasks under service accounts.
• Test scripts in a VM before production.

Key Points

• Invoke-Command runs across machines.
• Start-Job parallelizes long work.
• Register-ScheduledTask automates on a schedule.
• Secrets, logging and tests keep automation safe.
