Useful for scripting and automation purposes. Supports Windows 10 and Windows Server 2016 onwards. .DESCRIPTION Patch information retrieved from Microsoft Release Health / Update History (Server 2022) pages and outputted in a usable format. These sources are 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, 22H2. 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 full build number/s only. .PARAMETER ExcludePreview This parameter is optional. Excludes preview release/s. .PARAMETER ExcludeOutOfBand This parameter is optional. Excludes out-of-band release/s. .PARAMETER PreviewOnly This parameter is optional. Returns preview release/s only. .PARAMETER OutOfBandOnly This parameter is optional. Returns out-of-band/s only. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 22H2 Show all information on the latest available OS build for Windows 10 Version 22H2 in list format. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 22H2 -LatestReleases 2 Show all information on the latest 2 releases of OS builds for Windows 10 Version 22H2 in list format. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 22H2 -ExcludePreview -LatestReleases 2 Show all information on the latest 2 releases excluding preview of OS builds for Windows 10 Version 22H2 in list format. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 22H2 -ExcludeOutOfBand -LatestReleases 2 Show all information on the latest 2 releases excluding out-of-band of OS builds for Windows 10 Version 22H2 in list format. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 22H2 -PreviewOnly -LatestReleases 2 Show all information on the latest 2 preview releases of OS builds for Windows 10 Version 22H2 in list format. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 22H2 -OutOfBandOnly -LatestReleases 2 Show all information on the latest 2 out-of-band releases of OS builds for Windows 10 Version 22H2 in list format. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 22H2 -BuildOnly Show only the latest available OS build for Windows 10 Version 22H2 in list format. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 22H2 -PreviewOnly -BuildOnly Show only the latest available preview OS build for Windows 10 Version 22H2 in list format. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 22H2 -OutOfBandOnly -BuildOnly Show only the latest available out-of-band OS build for for Windows 10 Version 22H2 in list format. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 22H2 | ConvertTo-Json Show all information on the latest available OS build for Windows 10 Version 22H2 in json format. .EXAMPLE Get-LatestOSBuild -OSName Win10 -OSVersion 22H2 | ConvertTo-Json | Out-File .\Get-LatestOSBuild.json Save the json format to a file on the latest available OS build for Windows 10 Version 22H2. .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, [Parameter(Mandatory = $false)] [Switch]$PreviewOnly, [Parameter(Mandatory = $false)] [Switch]$OutOfBandOnly ) # 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") { $URL = "https://support.microsoft.com/en-us/help/5005454" } Else { Throw "Get-LatestOSBuild: Unsupported Operating System" } # Enforce OSVersion for LTSC Server OSName to prevent incorrect OSVersion input If ($OSName -eq "Server2016") { $OSVersion = "1607" } ElseIf ($OSName -eq "Server2019") { $OSVersion = "1809" } ElseIf ($OSName -eq "Server2022") { $OSVersion = "21H2" } # Function used for to convert raw array from support URL to a parsed array (currently used only for Server 2022) Function Convert-ParsedArray { Param($Array) $ArrayList = New-Object System.Collections.ArrayList ForEach ($item in $Array) { [Void]$ArrayList.Add([PSCustomObject]@{ Update = $item.outerHTML.Split('>')[1].Replace('</a','').Replace('—',' -
