LOGONUI.EXE

Question

Hello everyone,

I'm back with another problem! I feel like I have a VIRUS on my 2nd PC!

I have 2 computers at home, they are networked... everything works fine. The new PC has no virus, but the old one I believe has one!

It keeps displaying error windows. Like:
LOGONUI.EXE has encountered a problem and needs to close.

As a result, it closes all the open windows!! and I can't analyze if there are viruses... I only have KASPERSKY personal pro!

Apparently, the antivirus I have doesn't detect it either!! because I did an update this morning...

Can someone help me please?? It's very unpleasant to work on the PC like this!

Thank you all.

See you soon

What I tried to do is that I searched for the file in the system registry to see how it executes.
So I found it in the following location, of course after executing "regedit" from the start menu and run.
I found five HKEYs, each with its meaning.
I chose the third "HKEY_LOCAL_MACHINE"
then "SOFTWARE"
then "MICROSOFT"
then "WINDOWS NT"
then "CURRENTVERSION"
then "WINLOGON" and when I click on the latter without clicking on "+" it shows certain values on the left
AND FINALLY I found "UIHost" so what you will do if you found "logonui.exe" as data is to delete it by clicking on "UIHost" in the name column. A dialog box will appear. You delete its content and click on ok.
You will get rid of logonui permanently.

My logonui.exe file keeps crashing;

I already made a registry correction, but after an hour or two, it starts crashing again.
I did a system restore, but after an hour or two, it crashes again.
I formatted it, but after 2 or 3 days, it crashes again.
This results in messages like 0x00000000 memory cannot be written at every program launch and also Windows is insisting that I debug. So it’s a mess, I reformatted the day before yesterday and I received my PC last Friday.

This is a message from another person on another forum and it’s my case.

I had the same problem and I formatted my laptop and I still have the same issue; I couldn't find any other solution even if you search on drive C and delete it, this LOGONUI.EXE always comes back and it can cause damage to the system's operation and it can block everything on startup!
So I tried something else, I looked for another file in System32 with the same .exe extension. I made a copy of that one; I took the one from the calculator CALC.exe and I renamed this copy to logonui.exe
But you need to change its properties to read-only; the messages like 0x00000000 memory cannot be written disappeared, even the welcome blue screen is gone, but it works perfectly finally until now;

Hello

My problem is that my PC (Windows environment) won't shut down.
It shows me that there is an error logonui.exe.
How can I get past this issue because creating a copy and changing the name hasn't worked.

You need to change c:\windows\system32\logonui.exe to logonui.bak.

Bonjour, voici la traduction de votre message :

"Hello, here is my problem: it says that c:\windows\system32\dwmapi.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. In French, it translates to: it is either not designed to work on Windows or it contains errors. Try reinstalling the program using the original installation media or contact your system administrator or the software vendor for support. It also says logonUI.exe - bad image. Please help me, I don't know what to do, my PC won't start anymore, it just shows this error message and that's it."
