Hi willy

What mean you with check a os detection?

CODE

GetWinOS proc oBuF:DWORD
Local osvi:OSVERSIONINFOEX
mov osvi.dwOSVersionInfoSize,SIZEOF OSVERSIONINFO
invoke GetVersionEx, ADDR osvi

.if osvi.dwPlatformId == VER_PLATFORM_WIN32_NT
.if osvi.dwMajorVersion == 6 && osvi.dwMinorVersion == 0
.if osvi.wProductType==VER_NT_WORKSTATION
invoke lstrcpy,oBuF,CTEXT("Microsoft Windows Vista")
.else
invoke lstrcpy,oBuF,CTEXT("Microsoft Windows Server 2008")
.endif
.elseif osvi.dwMajorVersion == 5 && osvi.dwMinorVersion == 2
invoke lstrcpy,oBuF,CTEXT("Microsoft Windows Server 2003")
.elseif osvi.dwMajorVersion == 5 && osvi.dwMinorVersion == 1
invoke lstrcpy,oBuF,CTEXT("Microsoft Windows XP ")
.elseif osvi.dwMajorVersion == 5 && osvi.dwMinorVersion == 0
invoke lstrcpy,oBuF,CTEXT("Microsoft Windows 2000 ")
.elseif osvi.dwMajorVersion <= 4
invoke lstrcpy,oBuF,CTEXT("Microsoft Windows NT ")
.endif
.endif
ret
GetWinOS endp

or this

CODE

.386
.model flat,stdcall
option casemap:none

include \masm32\include\windows.inc
include \masm32\include\user32.inc
include \masm32\include\kernel32.inc

includelib \masm32\lib\user32.lib
includelib \masm32\lib\kernel32.lib

.data

Caption db "OS version Checking!",0
Msg db "It's based on NT",0
Msg2 db "It's based on 9x",0

.code
start:

mov ecx,cs
xor cl,cl
jecxz @NT

invoke MessageBox,NULL,addr Msg2,addr Caption,MB_OK
nop
nop
nop
nop
nop
invoke ExitProcess,0

@NT:
invoke MessageBox,NULL,addr Msg,addr Caption,MB_OK

invoke ExitProcess,0

end start

and here is a big routine with very many Os version

Hi

How can i detect os if Win7

CODE

;updated OSVERSIONEX structure

OSVERSIONINFOEXnew STRUCT
dwOSVersionInfoSize dd ?
dwMajorVersion dd ?
dwMinorVersion dd ?
dwBuildNumber dd ?
dwPlatformId dd ?
szCSDVersion db 128 dup(?)
wServicePackMajor dw ?
wServicePackMinor dw ?
wSuiteMask dw ?
wProductType db ?
wReserved db ?
OSVERSIONINFOEXnew ENDS

GetWinOS proc oBuF:DWORD
Local osvi:OSVERSIONINFOEXnew
mov osvi.dwOSVersionInfoSize,SIZEOF OSVERSIONINFO
invoke GetVersionEx, ADDR osvi

.if osvi.dwPlatformId == VER_PLATFORM_WIN32_NT
.if osvi.dwMajorVersion == 6 && osvi.dwMinorVersion == 1

.if osvi.wProductType == VER_NT_WORKSTATION
INVOKE MessageBox,0,CTEXT("Microsoft Windows 7"),0,MB_OK
.elseif osvi.wProductType != VER_NT_WORKSTATION
INVOKE MessageBox,0,CTEXT("Microsoft Windows Server 2008"),0,MB_OK
.endif

.IF (osvi.dwPlatformId == VER_PLATFORM_WIN32_NT) && (osvi.dwMajorVersion > 3)
; This program does not support dwMajorVersion less than 4
.IF (osvi.dwMajorVersion == 6)
.IF (osvi.dwMinorVersion == 0)
; Windows Vista or Windows Server 2008
.IF osvi.wProductType == VER_NT_WORKSTATION
invoke MessageBox,0, CTEXT("Windows Vista "),0,MB_OK
