Windows XP Easter Egg - Hello World

1. Open your resource editing program (I used XN Resource Editor)
2. Open "C:\WINNT\system32\taskmgr.exe" or "C:\WINDOWS\system32\taskmgr.exe" depending on what service packs you have installed.
3. On the left panel, open up Dialogs
4. Next, open number 109.
5. Finally, click English (United States) or Turkish (Turkey), and look at the dialog on the right.

If you don't find resource editor, you can download Resource Hacker from http://www.angusj.com/resourcehacker
