Getting Started / Install / Download

Method 1 - PowerShell Gallery

This is the recommended method, because it always gets the public release that has been tested, it's easy to remember, and supports all parameters.

Open PowerShell as Administrator and type

Install-Script Get-SystemInfo -Force

Follow the prompts to complete the installation (you can tap A to accept all prompts or Y to select them individually.

Note: -Force is optional but recommended, as it will force the script to update if it is outdated. If you do not use -Force, it will not overwrite the script if outdated.

Usage

Get-SystemInfo

The script is published on PowerShell Gallery under Get-SystemInfo.

---

Method 2 - One Line Command (Runs Immediately)

The URL asheroto.com/Get-SystemInfo always redirects to the latest code-signed release of the script.

If you just need to run the basic script without any parameters, you can use the following one-line command:

Option A: asheroto.com short URL

irm asheroto.com/Get-SystemInfo | iex

Option B: direct release URL

Alternatively, you can of course use the latest code-signed release URL directly:

irm https://github.com/asheroto/Get-SystemInfo/releases/latest/download/Get-SystemInfo.ps1 | iex

---

Method 3 - Download Locally and Run

As a more conventional approach, download the latest Get-SystemInfo.ps1 from Releases, then run the script as follows:

.\Get-SystemInfo.ps1

Tip

If for some reason your PowerShell window closes at the end of the script and you don't want it to, or don't want your other scripts to be interrupted, you can wrap the command in a powershell "COMMAND HERE". For example, powershell "irm asheroto.com/Get-SystemInfo | iex".

Parameters

No parameters are required to run the script, but there are some optional parameters to use if needed.

Parameter	Description
-CheckForUpdate	Checks if there is an update available for the script.
-UpdateSelf	Updates the script to the latest version.
-Version	Displays the version of the script.
-Help	Displays the full help information for the script.
-Silent	Suppresses output when the script is run, useful for dot-sourcing.

Usage

You can use the script in two ways:

1. Run the Script Directly
   If you’ve installed the script from the PowerShell Gallery, you can simply run the Get-SystemInfo command:

Get-SystemInfo

This will display all system diagnostics, including hardware details, OS version, disk usage, and more, directly to the console.

If you’re using the script file itself, execute it directly:

.\Get-SystemInfo.ps1

2. Call the Get-SystemInfo Function

To work with the diagnostics programmatically, retrieve them as an object. If installed via the PowerShell Gallery, you can call the function directly:

$info = Get-SystemInfo -Silent

Alternatively, if you have the script file, dot-source it to access the Get-SystemInfo function:

. .\Get-SystemInfo.ps1 -Silent

$info = Get-SystemInfo

This method allows access to specific sections of the diagnostics and integration into other scripts. See the next section for details.

Using the Get-SystemInfo Object

When invoked programmatically, the script returns all diagnostic information as a structured object, allowing for seamless access and manipulation. Specific sections of the diagnostics can be retrieved by accessing the corresponding properties of the object.
