Details:
The included tools utilizes some powerfull native functions in ntdll.dll. Theses functions are what lets you deal with invalid key names, because we can interact with the OBJECT_ATTRIBUTES structure; http://msdn.microsof...9(v=vs.85).aspx .
Since it uses native NT functions, it does not work with user friendly registry names like HKEY_LOCAL_MACHINE, HKCU etc. It will only take the Windows internal registry names, those starting with \Registry\... Below is a listing of the most important translations:

HKEY_LOCAL_MACHINE			 \registry\machine
HKEY_USERS					 \registry\user
HKEY_CURRENT_USER			 \registry\user\user_sid
HKEY_CLASSES_ROOT			 \registry\machine\software\classes
HKEY_CURRENT_CONFIG			\Registry\Machine\System\CurrentControlSet\Hardware Profiles\Current


The user sid is the one similar to this: S-1-5-21-2895024241-3518395705-1366494917-288

The syntax is:
RegKeyFixer.exe path -switch1 -switch2

Path can be in the format specified above

Switch1:

    -r switch is for renaming invalid key names
    -d switch is for deleting invalid key names
    -f switch is for just finding the invalid key names (just search, no repair)

Switch2

    -s switch is for recursive mode
    -n switch is for regular enumeration of subkeys


Some examples:

Recursively find and rename invalid keys found at HKLM\SOFTWARE and all its subkeys

RegKeyFixer.exe \Registry\Machine\SOFTWARE -r -s


Just find invalid key names at HKLM\SYSTEM\ControlSet001\services (no recursion, just enumerate 1 level down)

RegKeyFixer.exe \Registry\Machine\SYSTEM\ControlSet001\services -f -n



The tools have been tested on Windows 7 SP1 x64 and XP SP3 x86.
