body: <p>I have a little problem on my projects.
  My project is a mvc, do the following jobs.
  Using chrome to input data on forms, which then post to my controller
  to generate word document using dynamic datas input by replacing the word
  document templates.</p>
  
  <p>It finished this part perfectly by replacing the bookmarks,however, the
  only thing that border me is that after generating the word document,even
  i did not open the word that i generated,there is a word running in the background, and it keep starting a new one after generating new document.</p>
  
  <p>then after multiple generation, the computer becomes slow and i need to go to task manager to kill it one by one in order to release my memories again.</p>
  
  <p>What are the problems? and how do i solve it?</p>
