Toggle between two values in registry

[Vincent88]

Hi Guys, How to modify a batch script to toggle between the two values when execute. Any help would be much appreciated.

@echo off
for /F "skip=2 tokens=2*" %%A in ('reg query "HKLM\Software\microsoft\windows\CurrentVersion\Policies\System" /v "EnableLUA"') DO (Echo %%B)

If %%B==0x0 (
reg add HKLM\Software\microsoft\windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /D 1 /f
echo 1 %errorlevel%
) else (
reg add HKLM\Software\microsoft\windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /D 0 /f
echo  0 %errorlevel%
)

for /F "skip=2 tokens=2*" %%A in ('reg query "HKLM\Software\microsoft\windows\CurrentVersion\Policies\System" /v "EnableLUA"') DO (Echo %%B)
