Windows 7 Modify welcome message on login

Link Removed

I am trying to customize the "Welcome" message displayed after login in windows 7, I already have a message that displays on startup, which I made by opening regedit.exe and changing files in this dir HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System, but I am not sure where to find the file in which the value of "Welcome" is stored.

Thank you for your time and answers!

It's literally called Resource Hacker

Well, I watched your video all the way through, followed every step, but still did not get the desired result, it still just said Welcome... :/

-UPDATE- After a couple hours it started working. Thanks Neemobeer!
