With this plugin you are able to determine which version of windows you are running. Technically it is using the GetVersionEx() method from the "kernel32.dll".


  • check for a specific windows version:
    • IsWindows95
    • IsWindows98
    • IsWindowsME
    • IsWindowsNT351
    • IsWindowsNT40
    • IsWindows2000
    • IsWindowsXP
    • IsWindowsServer2003
    • IsWindowsXPx64
    • IsWindowsVista
    • IsWindowsServer2008
    • IsWindows7
    • IsWindowsServer2008R2
    • IsWindows8
    • IsWindowsServer2012
  • Call 'GetWindowsVersion' to get all relevant windows versioning infos:
    • major version
    • minor version
    • build number
    • platform id
    • service pack name
    • product type
  • Call platform methods to detect the windows platform type:
    • IsWindowsPlatformNT
    • IsWindowsPlatform9x

  Pop $MajorVersion
  Pop $MinorVersion
  Pop $BuildNumber
  Pop $PlatformID
  Pop $CSDVersion

  ${if} $ProductType == "1"
    MessageBox MB_OK "$PlatformID-platform, version $MajorVersion.$MinorVersion, build $BuildNumber, $CSDVersion, Workstation"
  ${ElseIf} $ProductType == "2"
    MessageBox MB_OK "$PlatformID-platform, version $MajorVersion.$MinorVersion, build $BuildNumber, $CSDVersion, DomainController"
  ${ElseIf} $ProductType == "3"
    MessageBox MB_OK "$PlatformID-platform, version $MajorVersion.$MinorVersion, build $BuildNumber, $CSDVersion, Server"

Version History

0.1 (03 sep 2004) (DNG)

  • First public release

0.2 (25 sep 2004) (DNG)

  • Implemented (proprietary) IntToStr-function since Delphi's SysUtils IntToStr requires more space (+ 24 kilobytes uncompressed)

0.3 (20 feb 2013) (TvT)

  • Bugfix: proprietary IntToStr method (from 0.2) is buggy: Returns '6.' instead of '6.0' for Windows Vista (same for W2K 5.0 or NT4.0) Thus using the well testet SysUtils IntToStr method is prefered over some kb in size
  • Added further methods for newer windows operating systems:
    • IsWindowsXPx64
    • IsWindowsVista
    • IsWindowsServer2008
    • IsWindows7
    • IsWindowsServer2008R2
    • IsWindows8
    • IsWindowsServer2012
  • The GetWindowsVersion() method returns the ProductType to be able to differentiate Server and Workstation windows versions
  • Removed inexisting (e.g. isWindows31) and useless (e.g. IsWindows98orLater) methods
  • Adapted the docs
