还要请教，我在msconfig中勾掉了那几个文件，可是

开机后提示“You have used the System Configuration Utility to make changes to the way Windows starts.The System Configuration Utility is currently in Diagnostic or Selective Startup mode, causing this message to be displayed and the utility to run every time Windows starts.Choose the Normal Startup mode on the General tab to start Windows normally and undo the changes you made using the System Configuration Utility.”
按照提示的改为normal startup后，那些文件又出现了。怎么才能删掉呢？
