title: Windows 2008 R2 - Kernel (System Process PID=4) is locking files and folders
body: <p>Windows 2008 R2 - Kernel (System Process PID=4) is locking files and folders for a long time.
  For example when deleting a file, the file may remain locked for 1 minute or more and only after that be deleted.
  On another occasions I encountered files or folders I could not delete. ProcMon showed that the System Process was holding a handle to those resources for a couple of minutes and then released them
  None of the resources I mentioned were system resources, only files and folders installed be me and handled by my applications.</p>
