So I sould use the %cdrom% tingy instead of %systemdrive% ? Is it installed? If yes) cool If no) should I make shortcuts to the files (it's only Media Player Cassic and Firefox deployment (taken from this site ))? Edit: What is the command (in example: programs.cmd) to execute something in the $OEM$ folder? cmdow @ /HID @echo off SET KEY=HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx REG ADD %KEY% /V TITLE /D "Installing Applications, and preparing everything" /f REG ADD %KEY%\080 /VE /D "Importing Registry Tweaks" /f REG ADD %KEY%\080 /V 1 /D "REGEDIT /S %systemdrive%\apps\regtweaks.reg" /f REG ADD %KEY%\085 /VE /D "Installing programs" /f REG ADD %KEY%\085 /V 1 /D "%systemdrive%\apps\programs.cmd" /f REG ADD %KEY%\085 /VE /D "Cleaning Up and Rebooting" /f REG ADD %KEY%\085 /V 1 /D "%systemdrive%\apps\cleanup.cmd" /f EXIT Would give me, what? A suggestion from myself (just to see if I have misunderstood everything) cmdow @ /HID@echo off SET KEY=HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx REG ADD %KEY% /V TITLE /D "Installing Applications, and preparing everything" /f REG ADD %KEY%\080 /VE /D "Importing Registry Tweaks" /f REG ADD %KEY%\080 /V 1 /D "REGEDIT /S %cdromdrive%\regtweaks.reg" /f REG ADD %KEY%\085 /VE /D "Installing programs" /f REG ADD %KEY%\085 /V 1 /D "%cdromdrive%\programs.cmd" /f REG ADD %KEY%\085 /VE /D "Cleaning Up and Rebooting" /f REG ADD %KEY%\085 /V 1 /D "%cdromdrive%\cleanup.cmd" /f EXIT[code] Should I then put regtweaks.reg, programs.cmd and cleanup.cmd in the root of the cd or in $OEM$ ? /ZoRo
