Windows File Protection (WFP) is a service of XP which protects important system files and other files crucial to the operation of Windows. Windows Resource Protection (WRP) is the WFP replacement new in Vista. The amount of protected files is drastically increased and protection is extended to registry keys. Vista does this by using Access Control Lists (ACLs) and limiting changes to protected files to one program: TrustedInstaller.exe. Administrators also have more limited control over changes in system files and registry keys: they no longer have default access; they must first change the ACL entry before access is granted to sensitive system files or registry keys.
Windows automaticly saves the registry in order to create a restore point. In windows you can restore the system to a previous set up, and part of that process is replacing or removing changed registry keys. Without these saved resistries restoration would be much harder, if not near impossible.

None. The only way to edit the registry in windows is to start an instance of the command prompt and then enter the word: regedit. Be very careful how you move about in the registry and also don't remove keys unless specifically told to be a qualified technician otherwise you can completely ruin your windows setup.
The registry is organized into keys and sub keys. Each key contains a value entry, and has a name, a type or class, and the value itself. The name is a string that identifies the key. The length and the format of the value depends on the data type.
You can manually go through the file structure and the registry and delete the files and registry keys belonging to the program. You can usually find out which files to delete and where they are by searching "manual uninstall [game name here]".
