Function Get-LatestOSBuild { <# .SYNOPSIS Gets windows patch release information (Version, Build, Availability date, Preview, Out-of-band, Servicing option, KB article, KB URL and Catalog URL) for Windows client and server versions. Useful for scripting and automation purposes. Supports Windows 10 and Windows Server 2016 onwards. .DESCRIPTION Patch information retrieved from the release health portal (https://docs.microsoft.com/en-gb/windows/release-health/release-information) and outputted in a usable format. This source is updated regularly by Microsoft AFTER new patches are released. This means at times this info may not always be in sync with Windows Update. .PARAMETER OSName This parameter is optional. OS name you want to check. Default value is Win10. Accepted values: Windows Client OS Names - Win10, Win11. Windows Server OS Names - Server2016, Server2019, Server2022, Server Semi-annual = ServerSAC. .PARAMETER OSVersion This parameter is mandatory. OS version number you want to check. Accepted values: Windows Client OS Versions: CB/CBB/SAC (Semi-Annual Channel) - 1507, 1511, 1607, 1703, 1709, 1803, 1809, 1903, 1909, 2004, 20H2, 21H2, 21H2. LTSB/LTSC (Long-Term Servicing Build/Channel) - 2015 = 1507, 2016 = 1607, 2019 = 1809, 2021 = 21H2. Window Server OS Versions: SAC (Semi-Annual Channel) - 1709, 1803, 1809, 1903, 1909, 2004, 20H2. LTSB/LTSC (Long-Term Servicing Build/Channel) - Server 2016 = 1607, Server 2019 = 1809, Server 2022 = 21H2. .PARAMETER LatestReleases This parameter is optional. Returns last x releases (where x is the number of releases you want to display). Default value is 1. .PARAMETER BuildOnly This parameter is optional. Returns only the full build number/s of the OS Version. .PARAMETER ExcludePreview This parameter is optional. Excludes preview releases. .PARAMETER ExcludeOutOfBand This parameter is optional. Excludes out-of-band releases. .EXAMPLE Get-CurrentOSBuild Show the currently installed OS Build release number. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 21H1 Show all information on the latest available OS Build for Windows 10 Version 21H1 in list format. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 21H1 -LatestReleases 2 Show all information on the latest 2 releases of OS Builds for Windows 10 Version 21H1 in list format. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 21H1 -ExcludePreview -LatestReleases 2 Show all information on the latest 2 releases (excluding preview) of OS Builds for Windows 10 Version 21H1 in list format. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 21H1 -ExcludeOutOfBand -LatestReleases 2 Show all information on the latest 2 releases (excluding out-of-band) of OS Builds for Windows 10 Version 21H1 in list format. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 21H1 -BuildOnly Show only the latest available OS Build for Windows 10 Version 21H1 in list format. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 21H1 | ConvertTo-Json Show all information on the latest available OS Build for Windows 10 Version 21H1 in json format. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 21H1 | ConvertTo-Json | Out-File .\Get-LatestOSBuild.json Save the json format to a file on the latest available OS Build for Windows 10 Version 21H1. .NOTES Forked from 'Get-Windows10ReleaseInformation.ps1' created by Fredrik Wall. https://github.com/FredrikWall/PowerShell/blob/master/Windows/Get-Windows10ReleaseInformation.ps1 Uses code adapted from 'Get-CurrentPatchInfo.ps1' created by Trevor Jones. https://gist.githubusercontent.com/SMSAgentSoftware/79fb091a4b7806378fc0daa826dbfb47/raw/0f6b52cddf82b2aa836a813cf6bc910a52a48c9f/Get-CurrentPatchInfo.ps1 #> Param( [CmdletBinding()] [Parameter(Mandatory = $true)] [String]$OSVersion, [Parameter(Mandatory = $false)] [String]$LatestReleases = 1, [Parameter(Mandatory = $false)] [ValidateSet('Win10','Win11','Server2016','Server2019','Server2022','ServerSAC')] [String]$OSName = "Win10", [Parameter(Mandatory = $false)] [Switch]$BuildOnly, [Parameter(Mandatory = $false)] [Switch]$ExcludePreview, [Parameter(Mandatory = $false)] [Switch]$ExcludeOutOfBand ) # Disable progress bar to speed up Invoke-WebRequest calls $ProgressPreference = 'SilentlyContinue' # Define variables for OSName If (($OSName) -eq "Win11") { $OSBase = "Windows 11" $URL = "https://docs.microsoft.com/en-us/windows/release-health/windows11-release-information" $TableNumber = 1 } ElseIf (($OSName) -eq "Win10" -or ($OSName) -eq "Server2016" -or ($OSName) -eq "Server2019" -or ($OSName) -eq "ServerSAC") { $OSBase = "Windows 10" $URL = "https://docs.microsoft.com/en-us/windows/release-health/release-information" $TableNumber = 2 } ElseIf (($OSName) -eq "Server2022") { $URL = "https://support.microsoft.com/en-us/help/5005454" } Else { Throw "Unsupported Operating System.
