is there anyway to change the windows wallpaper by using only a batch file?

Yes, that's possible, at least on Win98. The system (in your case, WinXP PRO) probably has a file where it stores the wallpaper name and location. On Win98, it's the file win.ini, on the windows folder. However, I don't know where is that information stored on WinXP. If you can find out that, I might be able to make a batch file to automatically change it. However, that information is more likely to be obtained on the Windows XP forum. If you get the information, email me. -- Leonardo Pignataro - Secret_Doom -- secret_doom@hotmail.com www.batch.hpg.com.br
