Function Get-WindowsVersion { <# .SYNOPSIS Get Windows version information .DESCRIPTION This is a PowerShell version of the winver.exe utility. This commands uses PowerShell remoting to query the registry on a remote machine to retrieve Windows version information.The parameters are the same as in Invoke-Command. .PARAMETER Computername Specifies the computers on which the command runs. The default is the local computer. When you use the ComputerName parameter, Windows PowerShell creates a temporary connection that is used only to run the specified command and is then closed. If you need a persistent connection, use the Session parameter. Type the NETBIOS name, IP address, or fully qualified domain name of one or more computers in a comma-separated list. To specify the local computer, type the computer name, localhost, or a dot (.). To use an IP address in the value of ComputerName , the command must include the Credential parameter. Also, the computer must be configured for HTTPS transport or the IP address of the remote computer must be included in the WinRM TrustedHosts list on the local computer. For instructions for adding a computer name to the TrustedHosts list, see "How to Add a Computer to the Trusted Host List" in about_Remote_Troubleshooting. On Windows Vista and later versions of the Windows operating system, to include the local computer in the value of ComputerName , you must open Windows PowerShell by using the Run as administrator option. .PARAMETER Credential Specifies a user account that has permission to perform this action. The default is the current user. Type a user name, such as User01 or Domain01\User01. Or, enter a PSCredential object, such as one generated by the Get-Credential cmdlet. If you type a user name, this cmdlet prompts you for a password. .PARAMETER UseSSL Indicates that this cmdlet uses the Secure Sockets Layer (SSL) protocol to establish a connection to the remote computer. By default, SSL is not used. WS-Management encrypts all Windows PowerShell content transmitted over the network. The UseSSL parameter is an additional protection that sends the data across an HTTPS, instead of HTTP. If you use this parameter, but SSL is not available on the port that is used for the command, the command fails. .PARAMETER ThrottleLimit Specifies the maximum number of concurrent connections that can be established to run this command. If you omit this parameter or enter a value of 0, the default value, 32, is used. The throttle limit applies only to the current command, not to the session or to the computer. .PARAMETER Authentication Specifies the mechanism that is used to authenticate the user's credentials. The acceptable values for this parameter are: - Default - Basic - Credssp - Digest - Kerberos - Negotiate - NegotiateWithImplicitCredential The default value is Default. CredSSP authentication is available only in Windows Vista, Windows Server 2008, and later versions of the Windows operating system. For information about the values of this parameter, see the description of the AuthenticationMechanismEnumeration (http://go.microsoft.com/fwlink/?LinkID=144382) in theMicrosoft Developer Network (MSDN) library. CAUTION: Credential Security Support Provider (CredSSP) authentication, in which the user's credentials are passed to a remote computer to be authenticated, is designed for commands that require authentication on more than one resource, such as accessing a remote network share. This mechanism increases the security risk of the remote operation. If the remote computer is compromised, the credentials that are passed to it can be used to control the network session. .EXAMPLE PS C:\> Get-WindowsVersion ProductName : Windows 10 Pro EditionID : Professional ReleaseId : 1809 Build : 17763.195 InstalledUTC : 12/17/2018 2:18:37 PM Computername : BOVINE320 Query the local host. .EXAMPLE PS C:\scripts> get-windowsversion -Computername srv1,srv2,win10 -Credential company\artd | format-table ProductName EditionID ReleaseId Build InstalledUTC Computername ----------- --------- --------- ----- ------------ ------------ Windows Server 2016 Standard Evaluation ServerStandardEval 1607 14393.2273 12/26/2018 4:07:25 PM SRV1 Windows Server 2016 Standard Evaluation ServerStandardEval 1607 14393.2273 12/26/2018 4:08:07 PM SRV2 Windows 10 Enterprise Evaluation EnterpriseEval 1703 15063.1387 12/26/2018 4:08:11 PM WIN10 Get windows version information from remote computers using an alternate credential. .Example PS C:\> Get-WindowsVersion -Computername win10 -AsString Windows 10 Enterprise Evaluation Version 1703 (OS Build 15063.1387) Get a string .INPUTS System.String .OUTPUTS Custom object .NOTES Learn more about PowerShell: http://jdhitsolutions.com/blog/essential-powershell-resources/ .LINK WinVer.exe .LINK Invoke-Command #> [cmdletbinding()] [OutputType("custom object")] [alias('wver')] Param ( [Parameter( Position = 0, ValueFromPipeline, ValueFromPipelineByPropertyName )] [ValidateNotNullOrEmpty()] [string[]]$Computername = $env:COMPUTERNAME, [PSCredential]$Credential, [switch]$UseSSL, [Int32]$ThrottleLimit, [ValidateSet('Default', 'Basic', 'Credssp', 'Digest', 'Kerberos', 'Negotiate', 'NegotiateWithImplicitCredential')] [ValidateNotNullorEmpty()] [string]$Authentication = "Default" ) Begin { Write-Verbose "Starting $($MyInvocation.MyCommand)" $sb = { $RegPath = 'HKLM:\SOFTWARE\Microsoft\Windows nt\CurrentVersion\' Get-ItemProperty -Path $RegPath | Select-Object -Property ProductName, EditionID, ReleaseID, @{Name = "Build"; Expression = { "$($_.CurrentBuild).$($_.UBR)" } }, @{Name = "InstalledUTC"; Expression = { ([datetime]"1/1/1601").AddTicks($_.InstallTime) } }, @{Name = "Computername"; Expression = { $env:computername } } } #close scriptblock #update PSBoundParameters so it can be splatted to Invoke-Command $PSBoundParameters.Add("ScriptBlock", $sb) | Out-Null $PSBoundParameters.add("HideComputername", $True) | Out-Null } #begin Process { if (-Not $PSBoundParameters.ContainsKey("Computername")) { #add the default value if nothing was specified $PSBoundParameters.Add("Computername", $Computername) | Out-Null } $PSBoundParameters | Out-String | Write-Verbose $results = Invoke-Command @PSBoundParameters | Select-Object -Property * -ExcludeProperty RunspaceID, PS* if ($AsString) { #write a version string for each computer foreach ($result in $results) { "{0} Version {1} (OS Build {2})" -f $result.ProductName, $result.releaseID, $result.build } } else { $results } } #process End { Write-Verbose "Ending $($MyInvocation.MyCommand)" } #end } #close function Function Get-WindowsVersionString { <# .SYNOPSIS Get Windows version information .DESCRIPTION This is a PowerShell version of the winver.exe utility.
