I'm using Windows XP Home Service Pack 2, and whenever I run something that uses a ton of memory and/or CPU such as running a MASH episode on WinAMP and closing it, a system process winlogon.exe's memory usage steadily increases and I've seen it up to 250k memory whereas normally it's around 600 to 4k. Does anyone know what's causing this or how to fix it? It really lags my computer.
