Well, you just have to understand how .INF files are made. After that, it's mad easy to setup. A little bit quoted from the 'Microsoft Windows XP Registry Guide': I used this [strings] part for A LOT of options. So you only have to change the string value, instead of looking at the registry key. Ie. in the AddReg section I have some lines called: [Reg.Settings] ... HKCU,"Software\Microsoft\Office\11.0\Outlook\Preferences","MinToTray",0x10001,"%Outlook.MinToTray%" HKCU,"Software\Microsoft\Internet Explorer\Main","Disable Script Debugger",0x00000,"%IE.DisableScriptDebugger%" HKCU,"Software\Microsoft\Ftp","Use PASV",0x00000,"%IE.FTPPassive%" ... Because they use variables, you have to edit the variable value instead of hard-code the desired value. This can be done at the [strings] section. The [strings] section looks like this: [Strings] ... Outlook.MinToTray = 1 IE.FTPPassive = yes IE.DisableScriptDebugger = Yes ... It's a little bit more work to enter a tweak for the first time, but after that you can change it's value EASIER than with .REG files. Because you don't have to worry for REG_SZ, REG_DWORD values, you can just enter what you want [and besides, I added descriptions for almost all values]
