title: an issue for "echo %temp%" in cmd.exe
body: <p>I'm facing a strange issue, when I executed the following command in a CMD.exe, will get different result in diff WKS. All WKS are windows-xp sp3.</p>
  
  <pre><code>c:\&gt; echo %temp%
  </code></pre>
  
  <p>one is: <code>C:\DOCUME~1\HWU\LOCALS~1\Temp</code>
  <br/>
  the other is: <code>C:\Documents and Settings\HWU\LOCALS~1\Temp</code></p>
  
  <p>I know, both results are the same position, but the second one will block our some batch file and I cannot modify batch file.</p>
  
  <p>So how can I modify some settings let result looks like the first one?</p>
  
  <p>Would anyone please advise?</p>
  
  <p>Thanks a lot!!!</p>
