Let's break this PowerShell script into logical parts and explain what it does:

Code Explanation:

1. Display | Where-Object { $_.InstanceId -like 'PCI\VEN_8086*' }

   • Display: Assumes this might be an object or command listing devices (e.g., output from Get-CimInstance Win32_PnPEntity or similar).
   • Where-Object { $_.InstanceId -like 'PCI\VEN_8086*' }: Filters the objects to only include those whose InstanceId property matches the wildcard pattern 'PCI\VEN_8086*'.
     • This pattern specifically looks for devices with a Vendor ID of 8086 (Intel Corporation), typically identifying Intel hardware.

2. Select-Object -Expand InstanceId

   • Takes the filtered output and extracts only the InstanceId property values from the objects. The -Expand parameter ensures that the output is an array of plain strings (not objects).

3. $path = Join-Path $share "$env:COMPUTERNAME.txt"

   • Constructs a file path string:
     • $share: A variable assumed to contain a base directory path (e.g., a network share or folder location).
     • "$env:COMPUTERNAME.txt": The current computer's name (retrieved from the $env:COMPUTERNAME environment variable) is used as the file name, with a .txt extension.
     • Join-Path: Combines the $share path and the filename into a single valid path.

4. $ids | Set-Content -Path $path -Encoding ASCII

   • Writes the filtered results ($ids), presumably containing the InstanceId values, to the file specified by $path.
     • Set-Content: Writes the output as text.
     • -Encoding ASCII: Ensures the content is written in ASCII encoding.

Summary:

This script identifies devices with an Intel Vendor ID (8086) by filtering their InstanceId values. It then writes these values into a file named <COMPUTERNAME>.txt in a specified shared directory.
