You forgot the quotes in REG ADD %KEY% /V TITLE /D "( TITLE HERE ) /f. And this SHOULD work with mine too, if you do NOT use start /wait rundll32.exe iernonce.dll,RunOnceExProcess, but run the Alternative RunOnceEx installer ONLY ONCE AT THE END. After inserting the first window entry's in the registry, you must set the %KEY% to (...)\Ruby Software\RunOnceEx2, to define the secound window. That should work. Example: @echo off cmdow @ /HID SET KEY="HKLM\SOFTWARE\Ruby Software\RunOnceEx" REG ADD %KEY% /V TITLE /D "( TITLE HERE )" /f REG ADD %KEY%\035 /VE /D "Chipset Software Installation Utility" /f REG ADD %KEY%\035 /V 1 /D "%systemdrive%\APPS\FIRSTBOOT\chipsetupdate.exe /s" /f REG ADD %KEY%\035 /V 2 /D "%systemdrive%\install\PAUSE.CMD REG ADD %KEY%\040 /VE /D "Visual Communication Camera VGP-VCC3 Driver" /f REG ADD %KEY%\040 /V 1 /D "%systemdrive%\APPS\FIRSTBOOT\CAMERADRIVER.EXE" /f REG ADD %KEY%\040 /V 2 /D "%systemdrive%\install\PAUSE.CMD REG ADD %KEY%\045 /VE /D "Alps StickPointer Driver" /f REG ADD %KEY%\045 /V 1 /D "%systemdrive%\APPS\FIRSTBOOT\alpspointer.exe" /f REG ADD %KEY%\045 /V 2 /D "%systemdrive%\install\PAUSE.CMD REG ADD %KEY%\050 /VE /D "Sony Image FilterDriver" /f REG ADD %KEY%\050 /V 1 /D "%systemdrive%\APPS\FIRSTBOOT\imagefilter\SonyImageFilter.exe /s" /f REG ADD %KEY%\050 /V 2 /D "%systemdrive%\install\PAUSE.CMD REG ADD %KEY%\055 /VE /D "Programmable I/O Driver" /f REG ADD %KEY%\055 /V 1 /D "%systemdrive%\APPS\FIRSTBOOT\programmableio.exe" /f REG ADD %KEY%\055 /V 2 /D "%systemdrive%\install\PAUSE.CMD REG ADD %KEY%\060 /VE /D "Gunze Touch panel Driver" /f REG ADD %KEY%\060 /V 1 /D "%systemdrive%\APPS\FIRSTBOOT\touchpanel.exe" /f REG ADD %KEY%\060 /V 2 /D "%systemdrive%\install\PAUSE.CMD REG ADD %KEY%\065 /VE /D "Sony USB Mouse Driver" /f REG ADD %KEY%\065 /V 1 /D "%systemdrive%\APPS\FIRSTBOOT\mousedri.exe" /f REG ADD %KEY%\065 /V 2 /D "%systemdrive%\install\PAUSE.CMD REG ADD %KEY%\070 /VE /D "LAN-Express Software" /f REG ADD %KEY%\070 /V 1 /D "%systemdrive%\APPS\FIRSTBOOT\LANExpress.exe" /f REG ADD %KEY%\070 /V 2 /D "%systemdrive%\install\PAUSE.CMD REG ADD %KEY%\075 /VE /D "Sony Batt Check" /f REG ADD %KEY%\075 /V 1 /D "%systemdrive%\APPS\FIRSTBOOT\batcheck.exe" /f REG ADD %KEY%\075 /V 2 /D "%systemdrive%\install\PAUSE.CMD REG ADD %KEY%\080 /VE /D "Setting Utility Series" /f REG ADD %KEY%\080 /V 1 /D "%systemdrive%\APPS\FIRSTBOOT\SUS.exe" /f REG ADD %KEY%\080 /V 2 /D "%systemdrive%\install\PAUSE.CMD REG ADD %KEY%\085 /VE /D "Sony Shared Library" /f REG ADD %KEY%\085 /V 1 /D "%systemdrive%\APPS\FIRSTBOOT\sharedlibrary.exe" /f REG ADD %KEY%\085 /V 2 /D "%systemdrive%\install\PAUSE.CMD REG ADD %KEY%\090 /VE /D "Sony Utilities DLL" /f REG ADD %KEY%\090 /V 1 /D "%systemdrive%\APPS\FIRSTBOOT\utildll.exe" /f REG ADD %KEY%\090 /V 2 /D "%systemdrive%\install\PAUSE.CMD SET KEY="HKLM\SOFTWARE\Ruby Software\RunOnceEx2" REG ADD %KEY% /V TITLE /D " ( SECOND WINDOW TITLE HERE )" /f REG ADD %KEY%\005 /VE /D "Vaio Control Center" /f REG ADD %KEY%\005 /V 1 /D "%systemdrive%\APPS\FIRSTBOOT\controlcenter.exe" /f REG ADD %KEY%\005 /V 2 /D "%systemdrive%\install\PAUSE.CMD REG ADD %KEY%\010 /VE /D "Vaio Event Service" /f REG ADD %KEY%\010 /V 1 /D "%systemdrive%\APPS\FIRSTBOOT\VES.exe" /f REG ADD %KEY%\010 /V 2 /D "%systemdrive%\install\PAUSE.CMD REG ADD %KEY%\015 /VE /D "Vaio Powermanagment" /f REG ADD %KEY%\015 /V 1 /D "%systemdrive%\APPS\FIRSTBOOT\powermgr.exe" /f REG ADD %KEY%\015 /V 2 /D "%systemdrive%\install\PAUSE.CMD REG ADD %KEY%\020 /VE /D "Special Button Utility" /f REG ADD %KEY%\020 /V 1 /D "%systemdrive%\APPS\FIRSTBOOT\SBU.exe" /f REG ADD %KEY%\020 /V 2 /D "%systemdrive%\install\PAUSE.CMD REG ADD %KEY%\025 /VE /D "Vaio Touch Launcher" /f REG ADD %KEY%\025 /V 1 /D "%systemdrive%\APPS\FIRSTBOOT\VTL.exe" /f REG ADD %KEY%\025 /V 2 /D "%systemdrive%\install\PAUSE.CMD RunOnceEx EXIT
