This really isn't an exploit, it's just file rename.

If you're using XP and already in command prompt, replacing Stcky Keys with CMD is unnecessary because XP doesn't have UAC, you can do this just from your desktop. The only time you'd need to do this is if you're on a PC with UAC and you're trying to change the password to someone elses account.

In this specific situation, the sticky keys method is worthless.

Plus,

"Now go to the system32 folder, It's usually in. C:/windows/System32"

Lmfao, really? It's not "usually" there, that is the location for x86 operating systems.
For x64, it's C:\Windows\SysWOW64
Although x64 still uses \System32\, that still may be a point in where you would find the files.
Only saying this because you have know knowledge on this if you're saying 'it's usually System32'
