There are no shortcuts to wmplayer.exe in any of the user Program Startup menus. I've checked all the Registry's "Run" keys and did not see any entry for wmplayer.exe. I looked up the names of the various programs that run as processes in my system and verified that they should be running as part of the system.
My email provider blocks all messages containing executable attachments before they get to me. I run Symantec Antivirus with continual updates of the virus definition files. I'm behind a hardware router and a software 2-way firewall (AtGuard).
What else should I do to prevent WMP from auto-starting? Thanks.
