Windows update?
control panel>network and internet>network and sharing center>advanced sharing settings..turn OFF file and print sharing...maybe turn off network discovery also if that doesnt wreck your network.
Network Discovery was still turned off but file and print sharing got turned on somehow..Maybe one of those update changes ? Odd my stuff was on hers but hers were not on mine. Just out of curiosity I had her put one of the photo albums in her recycle bin and it put it in mine also. I'm too old for this crap :)
