Automation and Task Scheduling
Schedule scripts, manage remote computers, and automate repetitive admin tasks.
What You'll Learn
- Creating and managing scheduled tasks from PowerShell
- PowerShell Remoting (Invoke-Command, Enter-PSSession)
- CIM/WMI queries for system information
- Real-world automation scripts for daily tasks
Task Scheduling
Windows Task Scheduler can be fully controlled from PowerShell — no GUI needed. You define three things: what to run (Action), when to run (Trigger), and how to run (Settings).
# Create a nightly backup task
$action = New-ScheduledTaskAction -Execute 'pwsh.exe' `
-Argument '-File C:\Scripts\backup.ps1'
$trigger = New-ScheduledTaskTrigger -Daily -At '2:00AM'
Register-ScheduledTask -TaskName 'NightlyBackup' `
-Action $action -Trigger $trigger -User 'SYSTEM'🎯 Real-World Analogy: Think of Task Scheduler as a reliable assistant who wakes up at the exact time you specify and runs your to-do list without supervision.
⚠️ Common Mistake
Scheduled tasks run in a non-interactive session — there's no console to see output. Always log results to a file: | Out-File C:\Logs\backup.log -Append. Also set -StartWhenAvailable so missed runs execute when the machine wakes up.
Scheduled Tasks
Create and manage scheduled tasks from PowerShell.
// PowerShell Automation — simulated in JavaScript
console.log("=== Scheduled Tasks ===");
console.log();
console.log("Create scheduled tasks directly from PowerShell:");
console.log();
console.log("$action = New-ScheduledTaskAction \\");
console.log(" -Execute 'pwsh.exe' \\");
console.log(" -Argument '-File C:\\Scripts\\backup.ps1'");
console.log();
console.log("$trigger = New-ScheduledTaskTrigger \\");
console.log(" -Daily -At '2:00AM'");
console.log();
console.log("$settings = New-Sc
...Remoting & System Queries
PowerShell Remoting lets you run commands on remote machines as if you were sitting at them. Enable it with Enable-PSRemoting on the target, then use Invoke-Command:
# Run on one machine
Invoke-Command -ComputerName Server01 -ScriptBlock {
Get-Service | Where Status -eq Running | Measure
}
# Run on multiple machines simultaneously
Invoke-Command -ComputerName Server01,Server02,Server03 {
Get-CimInstance Win32_OperatingSystem | Select Caption, FreePhysicalMemory
}CIM (Common Information Model) replaces the older WMI interface. Use Get-CimInstance to query hardware, OS, disk, network, and software information:
# Disk space report
Get-CimInstance Win32_LogicalDisk | Select DeviceID,
@{N='FreeGB'; E={[math]::Round($_.FreeSpace/1GB, 2)}},
@{N='TotalGB'; E={[math]::Round($_.Size/1GB, 2)}}Remoting & CIM
Remote management and system information queries.
// Remote Management & CIM — simulated in JavaScript
console.log("=== PowerShell Remoting ===");
console.log();
console.log("Run commands on remote computers:");
console.log();
console.log(" # Enable remoting (run as Admin on target)");
console.log(" PS> Enable-PSRemoting -Force");
console.log();
console.log(" # Run command on remote machine");
console.log(" PS> Invoke-Command -ComputerName Server01 -ScriptBlock {");
console.log(" Get-Service | Where Status -eq Running");
console.log("
...💡 Pro Tip
Combine PowerShell Remoting + Scheduled Tasks for enterprise automation: create a script that runs Invoke-Command on all your servers, then schedule it daily. You can manage an entire data centre from one machine.
📋 Quick Reference
| Cmdlet | Purpose |
|---|---|
| Register-ScheduledTask | Create a scheduled task |
| Invoke-Command | Run commands on remote machines |
| Enter-PSSession | Interactive remote session |
| Get-CimInstance | Query system hardware/software |
| Send-MailMessage | Send email alerts |
| Start-Job | Run script in background |
