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:

@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%]

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.
