This tutorial is a very good way to show off to your friends about how powerful you are. But this is just a basic Windows Hacking. First you need this tools:
Resource HackerTM is a freeware utility to view, modify, rename, add, delete and extract resources in 32bit Windows executables and resource files (*.res). It incorporates an internal resource script compiler and decompiler and works on Win95, Win98, WinME, WinNT, Win2000 and WinXP operating systems.- http://www.angusj.com/resourcehacker/
After that, run your ResHack and open for Explorer.exe file located in C:/WINDOWS/ folder. Please bear in mind to backup this file on another folder before for safety purpose because this file is a systems file. After you open the file, there will be some folder appears. Open folder String Table and open number 37 and click the 1033. You will see at the left hand side some text and one of the is "start". Just Change the start text into any text that you want. Just as simple as a,b,c. After that just save your file and restart the computer. This software will automatically create a backup file but it is more secure if you made it before start this changes. Thank you.
