kernel32 - GetSystemDirectory() outputs incorrect path

While attempting to enhance one of the programs, I noticed that while determining if a file is in the system32 directory, that it just didn't work. And if you were curious at what I was trying to do, I was experimenting with ways to install screensavers on ReactOS via the screensaver's context menu.

After doing a bit of digging, I noticed that the path name that GetSystemDirectory() was wrong. However, the only problem is that one of the letters is capitalized, when it should not be. From what I understand, Windows files/folder names are case sensitive. Also, I've checked with both XP and 7, and saw that the 'system32' folder name is all in lowercase.
