Create a text file in notepad. Save it. Then in windows right click on it, and rename it's extension from .txt to .bat.
Edit the batch file and put in whatever commands you need. Save and you're ready to go! Double click it to run it!
Note, you should make sure that extensions are TURNED ON in windows (windows sadly is by default set with extensions hidden, which is bad for security reasons anyway, so make sure they are visible in Folder Options in Windows explorer or whatever the equivalent is in XP these days!).
