I am not sure if this the right forum but here it goes anyway. Please feel free to move to the right forum. I am very very curious. Why is it that at times winlogon.exe is only using 6344K of my memory and at other times it jumps up to as high as 34000K and stays there unless i reboot. Does this mean anything? If I restart my laptop, it jumps back down to low levels. My specs are HP laptop, centrino 1.7, 1 gig RAM running WinXP Pro sp2, Nod32, MSAS, Kaspersky Anti-Hacker (all updated) TIA.
