试试这个：

@echo off
set "regpath=HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment"
call :setpath "D:\Siemens\swim\Origin_SWCustomer"
:setpath
if "%~$path:1"=="" reg add "%regpath%" /v Path /t REG_EXPAND_SZ /d "%path%;%1" /f
pause&exit
复制代码

如果只是想增加的环境变量在批处理内一次生效可用如下代码：

@echo off
call :setpath "D:\Siemens\swim\Origin_SWCustomer"
:setpath
if "%~$path:1"=="" path %path%;%1
pause&exit
复制代码

或者用下面这个：

@echo off
set regpath=HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment
set ADDpath=D:\Siemens\swim\Origin_SWCustomer
reg query "%regpath%" /v "Path"|find /i "%ADDpath%"||(reg add "%regpath%" /v Path /t REG_EXPAND_SZ /d "%path%;%ADDpath%" /f)
pause
