I don't know if I did something wrong but some RunOnceEx won't work for me in this case. In $OEM$ folder I have 6 files which are: autologon.reg, cmdlines.txt, hkcu.reg, hklm.reg, RunOnceEx.cmd and useraccounts.cmd Through autologon.reg and useraccounts.cmd I create new default user account for my installation and it's working good so far. Actually I wanted to remove some annoyances in my installation (like Windows tour popup, and desktop cleanup wizard selected by default etc.) but I can't achieve that. Here're contents of my files: cmdlines.txt: [COMMANDS] "useraccounts.cmd" "RunOnceEx.cmd" RunOnceEx.cmd: cmdow @ /HID @echo off SET KEY=HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx REG ADD %KEY% /V TITLE /D “Making changes to the default setup” /f REG ADD %KEY%50 /VE /D “Importing HKLM Registry Tweaks” /f REG ADD %KEY%50 /V 1 /D “REGEDIT /S hklm.reg” /f REG ADD %KEY%60 /VE /D “Importing HKCU Registry Tweaks” /f REG ADD %KEY%60 /V 1 /D “REGEDIT /S hkcu.reg” /f EXIT hkcu.reg: Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Desktop\CleanupWiz] “NoRun”=dword:00000001 [-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\MenuOrder\Start Menu] [-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\MenuOrder\Start Menu2] [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] “ForceClassicControlPanel”=dword:00000001 hklm.reg: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] “ForceClassicControlPanel”=dword:00000001 [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Applets\Tour] “RunCount”=dword:00000000 [-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\MyComputer\NameSpace\DelegateFolders\{59031a47-3f72-44a7-89c5-5595fe6b30ee}] And I also attached my WINNT.SIF file (just in txt mode) WINNT.txt
