I am receiving low memory warnings and freezes on a regular basis while idling. I've gone through most of the google recommend trouble shooting steps and I'm stuck with a weird recurring error in the event log. I have run a virus scan with malwarebytes... no hits.

I understand LogonUI.exe is part of windows. This is not normal windows 8.1 behavior. Why is LogonUI.exe trying to use more memory than what is available to my system? Is there any chance this is a hardware issue or does it have to be software?

OS: windows 8.1 pro RAM: 8 GB Event Log in question:

Event 2004, Resource Exhaustion-Detector Windows successfully diagnosed a low virtual memory condition. The following programs consumed the most virtual memory: LogonUI.exe (864) consumed 32235184128 bytes, sqlservr.exe (2104) consumed 279404544 bytes, and explorer.exe (4572) consumed 81514496 bytes.

    "Why is it eating so much of my RAM?" is asking for opinions and probably will be closed. Can you phrase it better? :) – Xavierjazz Jul 24 '14 at 14:35
  • Additionally, a question about abusrdly high resource consumption on Win8 looks like an excellent starting point for a rant or flamewar! I like it. – Eugen Rieck Jul 24 '14 at 15:29
  • Does this happen when you boot into a minimal configuration? 32,235,184,128 bytes isn't 8GB thats closer to 32GB ( 34,359,738,368 bytes would be 32GB ). – Ramhound Jul 24 '14 at 15:48
  • Good point I should have caught the byte to GB conversion. I will report back after doing a clean boot. I'm not trying to start a flame or opinion thread here. Do you have a recommendation on phrasing this differently than the new edit? – abaldwin99 Jul 24 '14 at 16:07
  • I followed the instructions exactly from microsoft for a clean boot: support.microsoft.com/kb/929135 When I try to log in the system hangs at "please wait". Do you think there's a relation? – abaldwin99 Jul 24 '14 at 16:24

Uninstalling "HP Simple Pass" from programs and features solved the problem for me.

I found the solution for it here: technet forum

In the previously posted screen shots of ProcessExplorer you can see a dll called OmniPassCredProv. Mine showed the same and the dll lives in c:\Program Files\Hewlett Packard\SimplePass.

That software appears to be for the finger print scanner which I don't use so I uninstalled it and now LoginUI no longer gobbles memory.


Three days with no issues so far. It appears my Windows files got corrupted somehow and using these commands restored it...

sfc /scannow

dism /online /cleanup-image /restorehealth

sfc /scannow

You can read about those commands here:
