```bat

@echo off

set Mainkey=HKCU\SOFTWARE\Microsoft\InputMethod\Settings\CHS

for /f %%i in ('reg query %MainKey% /v "Enable Double Pinyin" ^| findstr /i "0x1"') do (set flg=%%i)

if not defined flg (
reg add %MainKey% /v "Enable Double Pinyin" /t REG_DWORD /d 0x1 /f
echo 已经切换到双拼
) else (
reg add %MainKey% /v "Enable Double Pinyin" /t REG_DWORD /d 0x0 /f
echo 已经切换到全拼
)

pause
