I write some simple code about netstat-like.
I want to display network connection info and pid, process name, process 
username, cwd, exe and more..
But psutil.username, psutil,getcwd(), psutil.exe is occur errors.

psutil._error.AccessDenied: (pid=696, name='svchost.exe')

Maybe this error is my code has no priviliges to access svchost.exe.
Anyone know how to fix this error or why occur this error?

There's nothing you can do about that except maybe running the Python process 
as NT AUTHORITY SYSTEM user.
In general it is natural to expect AccessDenied exceptions when querying 
processes owned by another user, especially for lower PIDs.
