A PowerShell cmdlet that scrapes available Cumulative Updates from for various Windows operating systems.

This script parses various Microsoft-managed Atom feeds, filters on the actual Cumulative Updates, and returns a list based on parameters you may or may not want to use.

Get-WindowsUpdateFeed.ps1 -osVersion "Windows10"

This will return every Cumulative Update for Windows 10 ever published across all builds (at least as much as Microsoft is revealing through Atom).

Get-WindowsUpdateFeed.ps1 -osVersion "Windows10" -osBuild "18363"

This will return all Cumulative Updates for Windows 10, build 18363 (at least as much as Microsoft is revealing through Atom).

Get-WindowsUpdateFeed.ps1 -osVersion "Windows10" -osBuild "1904"

This will return all Cumulative Updates for Windows 10, builds 19041, 19042, and 19043. The filter is doing a .Contains(), so if you leave off a digit at the end, it will find any string that matches the beginning pattern.

Get-WindowsUpdateFeed.ps1 -osVersion "Windows10" -hoursSinceUpdatePublished 240

This will return all Cumulative Updates for Windows 10 that have been published in the last 10 days (240 hours).
