Multiple Winlogon.exe processes running

I have a Vista 64 Ultimate install and as days go by, my memory utilization continues to climb.  Checking Task Manager, I find that I have 8-10+ instances of Winlogon.exe running (only 4 users are defined on the machine; all logged off except me).  I can manually kill them or reboot the machine to reduce my memory utilization, but after 3-4 days I have the same problem again.  Please help!

Hi Ron,

 

I would suggest you to follow the steps mentioned below.

 

Step 1: Perform an online virus scan

Sometimes malware, spyware, adware, Trojan or viruses commonly hide behind the mask of Winlogon.exe consuming all the system resources. So, I would suggest you to perform a complete virus scan on your computer. Visit the link below for the same.

Step 2: Perform a clean boot

You can also try performing a clean boot to see if any third party services are causing this issue.

Note: Once the troubleshooting is done, reset the computer to start as usual.

 

Hope this information is helpful and let me know if you need any further assistance.
