Windows 8 personal file and lock

[nesetceri]

when my system starts up it always opens my personal file.. How do I stop it happening ?
Also when I put my desktop PC to sleep I tweaked it so when I wake it up I don't have to use password.. however when pc goes to sleep automatically when I wake it up it says it is locked and asking me for the password.. I just want to get rid of passwords (I am the only user) but how? Can I use my pc without Administrator, just myself as solo user ?
