title: VS2010 Cannot edit devenv.exe.config as crss.exe has a lock on it
body: <p>I am attempting to edit devenv.exe.config to implement the solution provided <a href="https://stackoverflow.com/questions/8524423/could-not-load-file-or-assembly-hresult-0x80131515-when-adding-controller-to-m">here</a>.</p>
  <p>as i believe it will solve an issue i am having with building a project.</p>
  <p>I cannot however edit the file as csrss.exe has a lock on it. A restart did not help. This exe is an os level exe which i cannot kill without taking down the os. i don't know what it has a lock on the config file as no vs tools are running.</p>
  <p>I have tried to boot into safe mode but have not been able to.</p>
  <p>Any help appreciated :)</p>
