Winlogon.exe sits at 50% cpu
Posted on 2006-06-12
After googling and other troubleshooting methods, i need some other opinions on this situation.
Running dell optiplex pentium4 with 1 gig of memory.
OS is xp sp2 with all the latest hotfixes.
The workstation (mine) was fine on friday when I left, but when I came in this morning I noticed that IE had the IE enhanced security enabled on it. I didn't install the enchanced security settings either. In IE on the security tab for the "internet" it is set to "high" and that is the only option now.
Another thing is my "winlogon.exe" process is taking 50-51% cpu usage in task manager. I have viewed this in other process exploreres and it shows 4 instances of "winlogon.exe" is running, but in the windows task manager it shows only one.
I have already ran all of your normal spyware, virus protection programs which include hijackthis, spybot, adaware, windows defender, trend micro, mcafee, panda, bitdefender. No viruses were found and only a few things were found for spyware/malware which looked like the normal entries I find all the time I scan.
My question is if it's not a virus/spyware then why/how/what made my IE settings be hardended over the weekend and the winlogon.exe process stay at 50%?
My main concern right now is the winlogon.exe process taking that much cpu usage at all times.
