I want to make Windows 7 case-sensitive when it reads/writes anything on the hard drive (the C drive, or any other NTFS drive).

I found a video via google that says to change the registry key

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\DontPrettyPath

to a value of 1 (source).

I also found a Windows support item that says something about modifying the registry key

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\kernel\obcaseinsensitive

that leads me to assume putting a value of 0 will make Windows case-sensitive with NTFS filesystems (source).

I have a feeling the second solution is the answer, but I'm not sure and I don't want to try it without being sure.

Does anyone know for sure what is the correct way to make Windows 7 case-sensitive when it reads/writes to the C drive (and any other NTFS drive)?
