Get-ItemProperty is a cmdlet in Windows PowerShell that retrieves the properties of a specified item. This cmdlet is particularly useful for accessing registry keys, file properties, and other system settings in a Windows environment. It allows users to query and manipulate system configurations efficiently.

Examples:

1. Retrieve Registry Key Properties:

   Suppose you want to get the properties of a registry key in Windows. You can use Get-ItemProperty to access the registry and retrieve specific values.

   # Retrieve properties of a registry key
   $registryPath = "HKLM:\Software\Microsoft\Windows\CurrentVersion"
   $properties = Get-ItemProperty -Path $registryPath
   Write-Output $properties

   In this example, the cmdlet retrieves all properties of the specified registry path. You can further filter the output to get specific property values.

2. Access File Properties:

   Get-ItemProperty can also be used to access file properties. For instance, if you want to get the properties of a file located at a specific path, you can do so as follows:

   # Retrieve properties of a file
   $filePath = "C:\Path\To\Your\File.txt"
   $fileProperties = Get-ItemProperty -Path $filePath
   Write-Output $fileProperties

   This command will display properties such as the file's creation time, last access time, and other attributes.

3. Filter Specific Properties:

   You can filter for specific properties by using the Select-Object cmdlet in conjunction with Get-ItemProperty.

   # Retrieve specific properties of a registry key
   $registryPath = "HKLM:\Software\Microsoft\Windows\CurrentVersion"
   $specificProperties = Get-ItemProperty -Path $registryPath | Select-Object -Property ProductId, ProductName
   Write-Output $specificProperties

   This example retrieves only the ProductId and ProductName properties from the specified registry path.

4. Using Get-ItemPropertyValue:

   For scenarios where you need only a single property value, you can use Get-ItemPropertyValue, which is more efficient.

   # Retrieve a single property value from a registry key
   $registryPath = "HKLM:\Software\Microsoft\Windows\CurrentVersion"
   $productId = Get-ItemPropertyValue -Path $registryPath -Name "ProductId"
   Write-Output $productId

   This command directly retrieves the ProductId value from the specified registry path.
