> Oh, I found how to start a task before the user login, and os.urandom() still works: it produces 16 bytes immediatly (in 0.0 second). Just to confirm: that's a fresh Windows VM, never been booted before ever? If it had ever been booted before, it might be saving its entropy pools to the hard disk at shutdown. If you do the experiment a second time with another copy of the same fresh VM, does it generate the same 16 bytes?
