PowerShell Script to Generate System Report Easily

Use the PowerShell script Get-ComputerInfo | Select-Object CsName, OsName, OsVersion, CsProcessors, CsTotalPhysicalMemory | Format-List to generate a simple system report showing computer name, OS, CPU, and memory details.

Examples

InputRun script on Windows 10 PC

OutputCsName : DESKTOP-12345 OsName : Microsoft Windows 10 Pro OsVersion : 10.0.19044 CsProcessors : {Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz} CsTotalPhysicalMemory : 17179869184

InputRun script on Windows Server 2019

OutputCsName : SERVER01 OsName : Microsoft Windows Server 2019 Standard OsVersion : 10.0.17763 CsProcessors : {Intel(R) Xeon(R) CPU E5-2676 v3 @ 2.40GHz} CsTotalPhysicalMemory : 34359738368

InputRun script on Windows 11 laptop

OutputCsName : LAPTOP-67890 OsName : Microsoft Windows 11 Pro OsVersion : 10.0.22000 CsProcessors : {AMD Ryzen 7 5800U} CsTotalPhysicalMemory : 17179869184

How to Think About It

To create a system report, gather key system information like computer name, operating system details, processor info, and memory size. Use PowerShell cmdlets to fetch this data and format it for easy reading.

Algorithm

1

Get system information using built-in PowerShell cmdlets.

2

Select relevant properties such as computer name, OS name, OS version, processor details, and total physical memory.

3

Format the selected information into a readable list.

4

Output the formatted system report to the console.

Code

powershell

Get-ComputerInfo | Select-Object CsName, OsName, OsVersion, CsProcessors, CsTotalPhysicalMemory | Format-List

Output

CsName : DESKTOP-12345
OsName : Microsoft Windows 10 Pro
OsVersion : 10.0.19044
CsProcessors : {Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz}
CsTotalPhysicalMemory : 17179869184

Dry Run

Let's trace running the script on a Windows 10 PC named DESKTOP-12345.

1

Get system info

Get-ComputerInfo returns all system properties including CsName=DESKTOP-12345, OsName=Microsoft Windows 10 Pro, OsVersion=10.0.19044, CsProcessors={Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz}, CsTotalPhysicalMemory=17179869184

2

Select properties

Select-Object picks CsName, OsName, OsVersion, CsProcessors, CsTotalPhysicalMemory from the full info

3

Format output

Format-List displays the selected properties in a readable list format

Step	Action	Value
1	Get-ComputerInfo	CsName=DESKTOP-12345, OsName=Microsoft Windows 10 Pro, OsVersion=10.0.19044, CsProcessors=Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz, Memory=17179869184
2	Select-Object	CsName, OsName, OsVersion, CsProcessors, CsTotalPhysicalMemory
3	Format-List	Formatted list output

Why This Works

Step 1: Gather system data

The Get-ComputerInfo cmdlet collects detailed system information from the computer.

Step 2: Choose relevant details

Using Select-Object, we pick only the important properties to keep the report clear and focused.

Step 3: Format for readability

Format-List arranges the output vertically so each property is easy to read.

Alternative Approaches

Using WMI objects

powershell

Get-WmiObject -Class Win32_OperatingSystem | Select-Object CSName, Caption, Version, BuildNumber

This method uses older WMI cmdlets but provides OS details; less comprehensive than Get-ComputerInfo.

Exporting report to a text file

powershell

Get-ComputerInfo | Select CsName, OsName, OsVersion, CsProcessors, CsTotalPhysicalMemory | Format-List | Out-File system_report.txt

Saves the report to a file for sharing or later review.

Using CIM cmdlets

powershell

Get-CimInstance -ClassName Win32_ComputerSystem | Select-Object Name, Manufacturer, Model, TotalPhysicalMemory

CIM cmdlets are newer and faster than WMI, good for hardware info.

Complexity: O(1) time, O(1) space

Time Complexity

The script runs in constant time because it queries fixed system properties once without loops.

Space Complexity

Uses constant space to hold system info objects; no large data structures are created.

Which Approach is Fastest?

Using Get-ComputerInfo is fast and comprehensive; CIM cmdlets are also efficient for hardware info.

Approach	Time	Space	Best For
Get-ComputerInfo	O(1)	O(1)	Full system info, easy to use
Get-WmiObject	O(1)	O(1)	Legacy systems, OS details
Get-CimInstance	O(1)	O(1)	Hardware info, modern cmdlets
