So, are you bored with the same Log On screen... each time you start you computer??? If yes, then this article is surely for you. To start, you must first know that the actual Log On screen of your Windows XP is stored in the C:WindowsSystem32 folder in your local disk. The file is named logonui.exe. You can download better Log On screens (featuring a HOT Ameriacn Pamela Anderson or a COOL Indian Aishwarya Rai and lots more...) from this website http://www.themexp.org. Now, to replace the "logonui.exe", you can use the 'Log On Loader' program which you can download from www.themexp.org itself. This is simplest way as the 'Log On Loader does all for you! But you being a hacker, you would like to manage everything manually... Well, I'm also like that!!! So, once you've downloaded the Log On Screen, you would probably want to delete the existing one and replace it with the downloaded one... Of course, anyone would first think of doing that... but there's a small problem here! When delete or replace the existing logonui.exe, after a few seconds it is restored automatically... and thus you get the same boring Log On screen. So, what are we going to do??? Simple, registry hack!!! First rename the Log On Screen you've just downloaded, to anything you want, e.g ishwon (the .exe is not necessary). Now, copy and paste it in the C:\WINDOWSsystem32 folder. Once this is done, open the Registry (by typing regedit from startRun). Then go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon. You'll find the string UIHost, where the value data is: logonui.exe. All you have to do is delete this value and replace it with the name you've given to your downloaded Log On screen (in this case ishwon.exe), of course don't forget to add the .exe in the end. Press the F5 key and close the registry! Ok, you've done it!!! You can now... log off to see your new Log On screen!!! Don't forget to tell me how it was.
