Display the current operating system version.


A very simple method of version checking is to pipe a version string into FIND, however there is a possibility that something which is a unique string today might match a minor version released in the future.

e.g. the following would also match "7.6.1"

ver | find "6.1" > nul
if %ERRORLEVEL% == 0 goto ver_2008R2

Batch file to find the current operating system version, for Vista and later:

@Echo off
For /f "tokens=4,5,6 delims=[]. " %%G in ('ver') Do (set _major=%%G& set _minor=%%H& set _build=%%I) 

Echo Major Version: [%_major%]
Echo Minor Version: [%_minor%]
Echo Build: [%_build%]

PowerShell to retrieve Version / Release ID

The VER command returns the Major/Minor / Build number, but does not include the Version/Release ID as displayed in Settings > About.

The Release ID is a 4 digit code - a 2 digit year plus 2 digit planned month of release.
DisplayVersion is a 4 digit code - a 2 digit year plus H1 or H2.. for 1st, 2nd releases.

Mobile, Desktop and Server releases will have the same Version/Release ID but different build numbers.

For Windows 10 up to May 2020 / 2004, this can be retrieved from the registry via the ReleaseID:

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

For all later versions, this can be retrieved from the registry via the DisplayVersion:

$ver = (Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion" -Name DisplayVersion).DisplayVersion

The ReleaseID is now deprecated and will return '2009' for 20H2 and all subsequent versions of Windows.

If ($release -eq '2009') {$ver} Else {$release}

Finding the version remotely

PowerShell can be used to find the OS versions of multiple machines across a domain:

Get-ADComputer -Filter {OperatingSystem -like "Windows 10*"} -Property * | Format-Table Name,OperatingSystem,OperatingSystemVersion -Wrap –Auto

Service Pack Level

This batch script or this PowerShell script will return the Service Pack level.

32 bit or 64 bit process detection

The environment variable PROCESSOR_ARCHITECTURE holds the following possible values:

64-bit process: AMD64 or IA64
32-bit process or WOW64 (32bit Program on 64 bit OS): x86

If we are running WOW64 then PROCESSOR_ARCHITEW6432 =AMD64

  // OS is 32bit
  // OS is 64bit

via David Wang @MSFT


If the version was successfully displayed %ERRORLEVEL% = 0
If a bad parameter is given %ERRORLEVEL% = 1
VER /? will not reset the ERRORLEVEL, this is a bug.

VER is an internal command.
