The use of PowerShell scripting has become integral to modern system administration, enabling automation, management, and troubleshooting of operating systems. This paper demonstrates comprehensive knowledge of PowerShell scripts by developing ten practical scripts that support essential OS functions. Each script is crafted with at least five commands or lines of code, accompanied by detailed explanations of each command’s purpose and operation. Moreover, the scripts are designed to be directly useful in managing and maintaining Windows operating environments, emphasizing automation, security, and efficiency.

Introduction

PowerShell is a powerful scripting language and shell framework developed by Microsoft, particularly suited for automating Windows OS tasks. With its extensive command set, known as cmdlets, and ability to handle complex scripting, PowerShell enables system administrators to streamline operations and improve system reliability. This paper presents ten scripts that illustrate this potential, each targeting specific administrative tasks, such as user management, system monitoring, file handling, and security configuration.

PowerShell Scripts Supporting Operating System Functions

1. User Account Creation Script

This script automates the creation of a new user account, assigning appropriate permissions and home directories.

# Create a new local user account

$username = "NewUser"


$password = Read-Host -AsSecureString "Enter password"


New-LocalUser -Name $username -Password $password -FullName "New User Account" -Description "Created via PowerShell"


Add user to Administrators group


Add-LocalGroupMember -Group "Administrators" -Member $username

Explanation: The script sets a username, prompts for a secure password, creates a new user, and includes the user in the Administrators group, facilitating administrative access.

2. System Update Check

This script checks for installed Windows updates and outputs the list.

# List installed Windows Updates

Get-HotFix | Select-Object HotFixID, InstalledOn, Description

Explanation: It retrieves installed hotfixes, helping administrators verify update status and system security compliance.

3. Disk Space Monitoring

This script reports disk space usage for all drives.

# Check disk space for all drives

Get-PSDrive -PSProvider 'FileSystem' | Select-Object Name, Used, Free, @{Name="PercentFree";Expression={[math]::Round($_.Free / ($_.Used + $_.Free) * 100, 2)}}

Explanation: It provides a quick overview of disk utilization, crucial for maintaining system performance.

4. Service Status Management

This script checks the status of a specific service and restarts it if stopped.

# Manage Windows service

$serviceName = "Spooler"


$service = Get-Service -Name $serviceName


if ($service.Status -eq 'Stopped') {


Start-Service -Name $serviceName


Write-Output "$serviceName service was stopped and has been started."


} else {


Write-Output "$serviceName service is running."


}

Explanation: Automates monitoring and recovery of vital services, minimizing downtime.

5. File Backup Script

This script copies specified files to a backup directory.

# Backup files

$sourcePath = "C:\ImportantFiles"


$backupPath = "D:\Backup\ImportantFilesBackup"


Copy-Item -Path $sourcePath\* -Destination $backupPath -Recurse

Explanation: Ensures data safety through routine backups, essential for disaster recovery plans.

6. CPU Usage Monitoring

This script monitors CPU usage and sends an alert if usage exceeds threshold.

# Monitor CPU usage

$cpuUsage = Get-Counter '\Processor(_Total)\% Processor Time'


if ($cpuUsage.CounterSamples.CookedValue -gt 80) {


Write-Output "High CPU usage detected: $($cpuUsage.CounterSamples.CookedValue)%"


}

Explanation: Allows proactive response to resource bottlenecks, preventing potential system overloads.

7. User Logon Tracking

This script retrieves recent user logon events from event logs.

# Get recent user logins

Get-WinEvent -LogName Security -FilterXPath "*[System[(EventID=4624)]]" -MaxEvents 10 | Select-Object TimeCreated, Message

Explanation: Facilitates security auditing by tracking user login activity.

8. Service Configuration Script

This script sets a specific service to start automatically on boot.

# Configure service startup type

$serviceName = "WinDefend"


Set-Service -Name $serviceName -StartupType Automatic

Explanation: Ensures critical services are running after reboots, maintaining security and stability.

9. System Uptime Check

This script reports how long the system has been running since last reboot.

# Check system uptime

$uptimeSeconds = (Get-CimInstance Win32_OperatingSystem).LastBootUpTime


$uptime = (Get-Date) - $uptimeSeconds


Write-Output "System Uptime: $($uptime.Days) days, $($uptime.Hours) hours, $($uptime.Minutes) minutes"

Explanation: Useful for maintenance scheduling and understanding system stability.

10. User Account Disabling

This script disables a specified user account for security purposes.

# Disable user account

Disable-LocalUser -Name "OldUser"

Explanation: Helps in managing user access, especially for users who no longer need system permissions.

Conclusion

The above scripts demonstrate a working knowledge of PowerShell, showcasing its ability to automate and support critical OS functions. Practical applications include user management, system monitoring, service control, and security maintenance. When combined, these scripts significantly enhance operational efficiency and security posture in Windows systems.
