Running windows 8 on an acer aspire laptop(home use), we had 3 accounts and mine was the administrator. After a couple of weeks I have returned to the laptop and my account is gone, with my girlfriends now the administrator (though it has changed name). I have full access, but fear that all of my data and programs built up over a year may be gone-is there anyway of finding out if my account and data still exist or can be recovered. She cannot even explain to me what she did.......also, how can I override all these security complications so this cannot happen again?
