How to find the Windows version from the PowerShell command line

How do I find which Windows version I'm using?

I'm using PowerShell 2.0 and tried:

PS C:\> ver
The term 'ver' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify tha
t the path is correct and try again.
At line:1 char:4
+ ver <<<< 
    + CategoryInfo          : ObjectNotFound: (ver:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

How do I do this?

Since you have access to the .NET library, you could access the OSVersion property of the System.Environment class to get this information. For the version number, there is the Version property.

For example,

PS C:\> [System.Environment]::OSVersion.Version

Major  Minor  Build  Revision
-----  -----  -----  --------
6      1      7601   65536

Details of Windows versions can be found here.

To get the Windows version number, as Jeff notes in his answer, use:
```
[Environment]::OSVersion
```
It is worth noting that the result is of type [System.Version], so it is possible to check for, say, Windows 7/Windows Server 2008 R2 and later with
```
[Environment]::OSVersion.Version -ge (new-object 'Version' 6,1)
```
However this will not tell you if it is client or server Windows, nor the name of the version.
Use WMI's Win32_OperatingSystem class (always single instance), for example:
```
(Get-WmiObject -class Win32_OperatingSystem).Caption
```
will return something like

Microsoft® Windows Server® 2008 Standard

Unfortunately most of the other answers do not provide information specific to Windows 10.

Windows 10 has versions of its own: 1507, 1511, 1607, 1703, etc. This is what winver shows.

Powershell:
(Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion").ReleaseId

Command prompt (CMD.EXE):
Reg Query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v ReleaseId

See also related question on superuser.

As for other Windows versions use systeminfo. Powershell wrapper:

PS C:\> systeminfo /fo csv | ConvertFrom-Csv | select OS*, System*, Hotfix* | Format-List


OS Name             : Microsoft Windows 7 Enterprise
OS Version          : 6.1.7601 Service Pack 1 Build 7601
OS Manufacturer     : Microsoft Corporation
OS Configuration    : Standalone Workstation
OS Build Type       : Multiprocessor Free
System Type         : x64-based PC
System Locale       : ru;Russian
Hotfix(s)           : 274 Hotfix(s) Installed.,[01]: KB2849697,[02]: KB2849697,[03]:...

Windows 10 output for the same command:

OS Name             : Microsoft Windows 10 Enterprise N 2016 LTSB
OS Version          : 10.0.14393 N/A Build 14393
OS Manufacturer     : Microsoft Corporation
OS Configuration    : Standalone Workstation
OS Build Type       : Multiprocessor Free
System Type         : x64-based PC
System Directory    : C:\Windows\system32
System Locale       : en-us;English (United States)
Hotfix(s)           : N/A

Get-WmiObject -Class Win32_OperatingSystem | ForEach-Object -MemberName Caption

Or golfed

gwmi win32_operatingsystem | % caption

Result

Microsoft Windows 7 Ultimate

This will give you the full version of Windows (including Revision/Build number) unlike all the solutions above:

(Get-ItemProperty -Path c:\windows\system32\hal.dll).VersionInfo.FileVersion

Result:

10.0.10240.16392 (th1_st1.150716-1608)

Since PowerShell 5:

Get-ComputerInfo
Get-ComputerInfo -Property Windows*

I think this command pretty much tries the 1001 different ways so far discovered to collect system information...

If you want to differentiate between Windows 8.1 (6.3.9600) and Windows 8 (6.2.9200) use

(Get-CimInstance Win32_OperatingSystem).Version

to get the proper version. [Environment]::OSVersion doesn't work properly in Windows 8.1 (it returns a Windows 8 version).

I am refining one of the answers

I reached this question while trying to match the output from winver.exe:

Version 1607 (OS Build 14393.351)

I was able to extract the build string with:

,((Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion" -Name BuildLabEx).BuildLabEx -split '\.') | % {  $_[0..1] -join '.' }

Result: 14393.351

Updated: Here is a slightly simplified script using regex

(Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion").BuildLabEx -match '^[0-9]+\.[0-9]+' |  % { $matches.Values }

PS C:\> Get-ComputerInfo | select WindowsProductName, WindowsVersion, OsHardwareAbstractionLayer

returns

WindowsProductName    WindowsVersion OsHardwareAbstractionLayer
------------------    -------------- --------------------------
Windows 10 Enterprise 1709           10.0.16299.371

As MoonStom says, [Environment]::OSVersion doesn't work properly on an upgraded Windows 8.1 (it returns a Windows 8 version): link.

If you want to differentiate between Windows 8.1 (6.3.9600) and Windows 8 (6.2.9200), you can use (Get-CimInstance Win32_OperatingSystem).Version to get the proper version. However this doesn't work in PowerShell 2. So use this:

$version = $null
try {
    $version = (Get-CimInstance Win32_OperatingSystem).Version
}
catch {
    $version = [System.Environment]::OSVersion.Version | % {"{0}.{1}.{2}" -f $_.Major,$_.Minor,$_.Build}
}

Use:

Get-WmiObject -class win32_operatingsystem -computer computername | Select-Object Caption

I took the scripts above and tweaked them a little to come up with this:

$name=(Get-WmiObject Win32_OperatingSystem).caption
$bit=(Get-WmiObject Win32_OperatingSystem).OSArchitecture

$vert = " Version:"
$ver=(Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion").ReleaseId

$buildt = " Build:"
$build= (Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion").BuildLabEx -match '^[0-9]+\.[0-9]+' |  % { $matches.Values }

$installd = Get-ComputerInfo -Property WindowsInstallDateFromRegistry

Write-host $installd
Write-Host $name, $bit, $vert, $ver, `enter code here`$buildt, $build, $installd

To get a result like this:

Microsoft Windows 10 Home 64-bit Version: 1709 Build: 16299.431 @{WindowsInstallDateFromRegistry=18-01-01 2:29:11 AM}

Hint: I'd appreciate a hand stripping the prefix text from the install date so I can replace it with a more readable header.

If you are trying to decipher info MS puts on their patching site such as https://technet.microsoft.com/en-us/library/security/ms17-010.aspx

you will need a combo such as:

$name=(Get-WmiObject Win32_OperatingSystem).caption $bit=(Get-WmiObject Win32_OperatingSystem).OSArchitecture $ver=(Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion").ReleaseId Write-Host $name, $bit, $ver

Microsoft Windows 10 Home 64-bit 1703

Windows PowerShell 2.0:

$windows = New-Object -Type PSObject |
           Add-Member -MemberType NoteProperty -Name Caption -Value (Get-WmiObject -Class Win32_OperatingSystem).Caption -PassThru |
           Add-Member -MemberType NoteProperty -Name Version -Value [Environment]::OSVersion.Version                     -PassThru

Windows PowerShell 3.0:

$windows = [PSCustomObject]@{
    Caption = (Get-WmiObject -Class Win32_OperatingSystem).Caption
    Version = [Environment]::OSVersion.Version
}

For display (both versions):

"{0}  ({1})" -f $windows.Caption, $windows.Version

Test

(Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion" -Name BuildLabEx).BuildLabEx

To produce identical output to winver.exe in PowerShell v5 on Windows 10 1809:

$Version = Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\'
"Version $($Version.ReleaseId) (OS Build $($Version.CurrentBuildNumber).$($Version.UBR))"

This will give you the full and CORRECT (the same version number that you find when you run winver.exe) version of Windows (including revision/build number) REMOTELY unlike all the other solutions (tested on Windows 10):

Function Get-OSVersion {
Param($ComputerName)
    Invoke-Command -ComputerName $ComputerName -ScriptBlock {
        $all = @()
        (Get-Childitem c:\windows\system32) | ? Length | Foreach {

            $all += (Get-ItemProperty -Path $_.FullName).VersionInfo.Productversion
        }
        $version = [System.Environment]::OSVersion.Version
        $osversion = "$($version.major).0.$($version.build)"
        $minor = @()
        $all | ? {$_ -like "$osversion*"} | Foreach {
            $minor += [int]($_ -replace".*\.")
        }
        $minor = $minor | sort | Select -Last 1

        return "$osversion.$minor"
    }
}

I searched a lot to find out the exact version, because WSUS server shows the wrong version. The best is to get revision from UBR registry KEY.

    $WinVer = New-Object –TypeName PSObject
$WinVer | Add-Member –MemberType NoteProperty –Name Major –Value $(Get-ItemProperty -Path 'Registry::HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion' CurrentMajorVersionNumber).CurrentMajorVersionNumber
$WinVer | Add-Member –MemberType NoteProperty –Name Minor –Value $(Get-ItemProperty -Path 'Registry::HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion' CurrentMinorVersionNumber).CurrentMinorVersionNumber
$WinVer | Add-Member –MemberType NoteProperty –Name Build –Value $(Get-ItemProperty -Path 'Registry::HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion' CurrentBuild).CurrentBuild
$WinVer | Add-Member –MemberType NoteProperty –Name Revision –Value $(Get-ItemProperty -Path 'Registry::HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion' UBR).UBR
$WinVer

You can use python, to simplify things (works on all Windows versions and all other platforms):

import platform

print(platform.system()) # returns 'Windows', 'Linux' etc.
print(platform.release()) # returns for Windows 10 or Server 2019 '10'

if platform.system() = 'Windows':
    print(platform.win32_ver()) # returns (10, 10.0.17744, SP0, Multiprocessor Free) on windows server 2019

Using Windows Powershell, it possible to get the data you need in the following way

Caption:

(Get-WmiObject -class Win32_OperatingSystem).Caption

ReleaseId:

(Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion" -Name ReleaseId).ReleaseId

version:

(Get-CimInstance Win32_OperatingSystem).version

[solved]

#copy all the code below:
#save file as .ps1 run and see the magic

 Get-WmiObject -Class Win32_OperatingSystem | ForEach-Object -MemberName Caption
 (Get-CimInstance Win32_OperatingSystem).version


#-------------comment-------------#
#-----finding windows version-----#

$version= (Get-CimInstance Win32_OperatingSystem).version
$length= $version.Length
$index= $version.IndexOf(".")
[int]$windows= $version.Remove($index,$length-2)  
$windows
#-----------end------------------#
#-----------comment-----------------#

$OSVersion = [Version](Get-ItemProperty -Path "$($Env:Windir)\System32\hal.dll" -ErrorAction SilentlyContinue).VersionInfo.FileVersion.Split()[0]

On Windows 10 returns: 10.0.10586.420

You can then use the variable to access properties for granular comparison

$OSVersion.Major equals 10
$OSVersion.Minor equals 0
$OSVersion.Build equals 10586
$OSVersion.Revision equals 420

Additionally, you can compare operating system versions using the following

If ([Version]$OSVersion -ge [Version]"6.1")
   {
       #Do Something
   }
