title: How can I make windows explorer immediately notice that deleting desktop.ini?
body: <p>I'm using <strong>SHGetSetFolderCustomSettings</strong> function to customize a folder icon. This function give me a proper result. However, I never find a way to turn customized folder to normal folder who has not desktop.ini. When I deleted it, expected result did not come. I probably guess that explorer's cache. So, I tried to flush private profile cache on explorer by calling <strong>WritePrivateProfileString(NULL, NULL, NULL, L"desktop.ini")</strong>. Unfortunately, I got failed.  </p>
  
  <p>How should I do to solve that?</p>
