title: My bat file can't run correctly, why?
body: <p>Create a new file test.bat, the content is as follows:</p>
  
  <blockquote>
    <p>echo aa;</p>
  </blockquote>
  
  <p>and execute it in the dos command line,</p>
  
  <blockquote>
    <p>test.bat</p>
  </blockquote>
  
  <p>there are no output in the window. But when I tested it in another computer, it outputs </p>
  
  <blockquote>
    <p>aa</p>
  </blockquote>
  
  <p>When I double click the bat file, it always disappeared suddenly even I add a "pause" clause line in the test.bat file. Both the systems are Window XP. Can sb tell me where is the problem, please?</p>
  
  <p>I have checked all the things Mofi suggested, but the problem remains.</p>
  
  <p>Now, I divscover when reboot to the system using another Administrator account. All is fine.</p>
  
  <p>So, whether the problem comes from the registry record of the Windows XP?  </p>
