[RegistryKeys] deals with registry keys for which to manage portability. They come in the form file name=registry key location; the file name is the location of the place where it is saved, which is in Data\settings\file name.reg. If you wish to have drive letters updated inside this, look at [FileWriteN] with Type=Replace.
If you do not wish to save the data of the registry key to a file but only want to keep it safe and throw away any changes, set the “file name” to -, so you end up with -=registry key location.
Some more description of how this works and what it can be used to do is available in Dealing with the registry.
Example: appname_portable=HKCU\Software\AppName
These are registry values to set for running the portable application, useful for things like disabling file association writing. They come in the form HK??\*\Key\Value=REG_[TYPE]:[value]; the key name is the place in the registry, with the value appended to it after a final slash, and the value is of the form REG_TYPE:value; REG_TYPE: is optional, and defaults to REG_SZ (a string).
Note: if there is any possibility that the value does contain a colon, write the type explicitly.
Examples: HKCU\Software\AppName\Key\Value=REG_DWORD:16, HKCU\Software\AppName\Key\Value2=REG_SZ:%PAL:DataDir%
Key names are consecutive integers, starting at 1 (i.e. 1, 2, 3, etc.)
These are registry keys which get cleaned up after the application has run if they are empty. This is useful if there is a tree which will be left behind, for example, if something stores to HKEY_CURRENT_USER\Software\Publisher\AppName, when AppName is saved, Publisher will still be left, empty. Remove it with a line in here.

Example: 1=HKCU\Software\Publisher
Key names are consecutive integers, starting at 1 (i.e. 1, 2, 3, etc.)
These are registry keys which get removed after the application has run. This is useful if there is a tree of useless information which will be left behind, for example, if something stores temporary data to HKEY_CURRENT_USER\Software\AppName\Temp. Remove it with a line in here.
Example: 1=HKCU\Software\Publisher
Key names are consecutive integers, starting at 1 (i.e. 1, 2, 3, etc.)
These are registry values which get backed up before hand and restored later, but any value which may have been set while the portable application is running will be deleted. This can be useful for “dead” values which serve no purpose and so there is no point in saving them anywhere.
Example: 1=HKCU\Software\Publisher\AppName\Value
