I'm having the exact same issue and thought I was going nuts. I even had the one person who had shared a note with me unshare and delete the note on their end to see if that fixed it, but it didn't, it still goes there every time I reopen the app, whether quitting all the way or just closing the app but letting it continue to run in the system tray.
EN 10.1 keeps opening in the Shared With Me window rather than last used
in Evernote for Windows Issues (Versions 10.0 and above)
