bat批处理判断系统32位或64位以及操作系统类型

方法一：

systeminfo |find "x64"

方法二：

有时候需考虑wow的情况

IF PROCESSOR_ARCHITECTURE == amd64 or

PROCESSOR_ARCHITEW6432 == amd64 THEN

// OS is 64bit

ELSE

// OS is 32bit

END IF

Another way to test for the same thing is:

IF PROCESSOR_ARCHITECTURE == x86 AND

PROCESSOR_ARCHITEW6432 NOT DEFINED THEN

// OS is 32bit

ELSE

// OS is 64bit

END IF

var中存储的数据，PROCESSOR_ARCHITECTURE存储的内容

@echo off

for /f "tokens=1* delims=[" %%a in ('ver') do set b=%%b

set b=%b:* =%

goto %b:~0,4%%PROCESSOR_ARCHITECTURE:~-1%

:5.1.6

echo xp_32位

goto:eof

:6.1.6

echo win7_32位

goto:eof

:6.1.4

echo win7_64位

:6.0.6

echo vista_32

exit

:6.0.4

echo vista_64

exit
