Question

Build.bat

@echo off
echo Disabling UAC, please wait...
start DisableUAC.lnk
echo UAC Disabled Successfully!
echo.
pause

DisableUAC.bat:

C:\Windows\System32\cmd.exe /k %windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0 /f

To run DisableUAC.bat with administrative privileges, I created a shortcut DisableUAC.lnk and checked properties > shortcut > advanced and checked “Run as administrator.” Then I call for it inside Build.bat

This all works, but how can I get the command prompt that shows up from DisableUAC.bat to close upon completing the task? (keep the main Build.bat open, close the DisableUAC.bat that pops up)

Answer 1

Change /k to /c:

C:\Windows\System32\cmd.exe /c %windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0 /f

See cmd /?:

Starts a new instance of the Windows command interpreter

CMD [/A | /U] [/Q] [/D] [/E:ON | /E:OFF] [/F:ON | /F:OFF] [/V:ON | /V:OFF]
[[/S] [/C | /K] string]

/C Carries out the command specified by string and then terminates
/K Carries out the command specified by string but remains
..

Although I don’t think you need to start a new cmd.exe at all here? I think this would also work, either directly as a shortcut or in DisableUAC.bat:

%windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d
