title: Access denied to file on windows 7 for Administrator account
body: <p>I want to delete my git repository (.git folder) created by git on my windows 7 box. It says access denied to .git/refs/header folder.</p>
  
  <p>I open a console with Administrator role, issue command "takeown /F heads /A /R", it still says "ERROR: Access is denied.", neither can i do via GUI security dialog.</p>
  
  <p>Any suggestion?</p>
