title: Permission denied with MinGW even as administrator
body: <p>I recently updated my MinGW installation on Windows 10, so I tried to compile a quick sample program in C. No problem, it compiles.</p>
  
  <p>However, when I try to compile after the first time, I get an error telling me that MinGW can't access the exe file. I tried to run MinGW as administrator, without success.</p>
  
  <p>Then, I tried to delete the exe. And I found that, even as administrator, and even with the hidden administrator account, I can't delete it. "Permission denied" and so on. I can't edit file's permissions neither. </p>
  
  <p>So the question is simple: what's going on?</p>
