Save-MSCatalogUpdate

Use the Save-MSCatalogUpdate command to download update files from the Microsoft Update Catalog. Download updates specified by an object returned from Get-MSCatalogUpdate:

$update = Get-MSCatalogUpdate -Search "Cumulative Update for Windows 11 Version 24H2" -ExcludeFramework
Save-MSCatalogUpdate -update $update -Destination ".\"

Save-MSCatalogOutput

The Save-MSCatalogOutput function allows you to save the output from the Get-MSCatalogUpdate command to an Excel file. This is particularly useful for maintaining a record of updates retrieved from the Microsoft Update Catalog.

Before using the Save-MSCatalogOutput function, ensure that you have the ImportExcel module installed. You can install it using the following command:

Install-Module -Name ImportExcel

By default, the worksheet name in the Excel file will be named "Updates". However, you can customize the worksheet name by specifying the -WorksheetName parameter.

Save-MSCatalogOutput -Update $update -WorksheetName "08_2024_Updates" -Destination "C:\Temp\2024_Updates.xlsx"

HtmlAgilityPack

MSCatalogLTS uses the HtmlAgilityPack library for HTML parsing to ensure cross-platform compatibility. This avoids reliance on the Windows-only ParsedHtml property of the Invoke-WebRequest CmdLet.
