Okay, my pc is officially insane. Yes if one can call Win XP bonkers....that's what mine is.
The latest in this ordeal is that...the login screen shows up when it wants to at different boot ups. I might run ccleaner and shut down right now and when I reboot. There'll be no login screen....and tomorrow I may do the same and for no reason the log in screen will show up. The other thing is that...you know when you hit start>>>shut down>>>and the shut down options come up...well mine have changed. Where it used to be this:
it's turned to this:

Why? That's what I'd like to know...I think it changed styles when I went to control panel>>>user accounts.
Still it makes no sense why the setting in Tweak UI keeps changing when I run Ccleaner. Only it's random!! Why am I plagued with this login screen all of a sudden? What the ef? I'm about to go on "Pierre Bernard's recliner of rage!" lol
