Thanks for the info guys ! I have had trouble with viruses and spyware in the last few weeks thanks to a friend who plugged his laptop into mine as a network when I was downstairs. I'm still worried obviously that I may be infected somewhere even though the virus scanners and spyware scanners are saying i'm clean. Not that i've had any symptoms recently but i'm just being cautious. Is it possible that there is a hidden exe somewhere than my virus scanners are not detecting that perhaps winlogon.exe could be loading each time I load my computer?

you should normally have quite a few winlogon.exe running processes at the same time. Depends on what software you use. It's a System process.

I've seen something similar at work. One machine had a buggy installation of Automatic Updates. It just kept on assigning more and more resources to AU (I guess, because the problem was worked around by disabling the service).

The symptom was that winlogon.exe grew and grew at about +60 MB/hour and at the end of a workday it would have consumed over 400 MB of memory and constantly use 99 % of the CPU time. Needless to say, your solution fixed my winlogon.exe problem.

When my computer was on, my cpu spikes to 100% every 3-4 seconds on and off. I've figured out that winlogon.exe is causing this problem but i didn't know how to fix until I read this article. Everything looking good now.

When my memory usage gets too high, I naturally open one of the programs I have to refresh/restore my memory. I know that, odds are, its presence is worse on my memory than how much it frees, but it comforts me.

One thing I've found interesting is that one of the 7 winlogon.exes I have running at all times is a major memory hog. We're talking upwards of 25-35 meg of memory. If I use CachemanXP to reduce its memory usage, it goes down to around 7 for a while.

If I kill this winlogon.exe, I lose sound. Winamp won't play music, dings and bleeps won't bleep and ding, etc.

But the solution mentioned here is right on the money. The scanning tool fixed my registry conflicts and all the memory issues are history now. Thanks!
