runtime error system32/logonUI.exe

I have an error message on my computer that I had ITok.net take a stab at removing/fixing. They spent nearly 3 days doings all kinds of operationshe error still persists.  I checked the C:System 32 folder and I couldn't even find that file, although I know I saw it there when the tech was looking at it. He was working on my computer remotely. I have found a way to log on around the error, but Idon't want to worry about further damage to my computer. What would you suggest. P.S. I'm not a computer wiz!!!!! Jen Moore *** Email address is removed for privacy ***  .

Hi Jen,

 

LogonUI.exe belongs to Windows and from the error message it appears that the file is corrupted. Here’s what you can do.

 

Running System File Checker [SFC] scan might help you to get rid of this error message at the startup. SFC scan replaces the corrupted system files with the original version of Windows files on the computer.

I have the same problem on my son's login for Windows 10, but the dialog box "Runtime Error C:\WINDOWS\system32\LogonUI.exe" appears before he can log in, and if "OK" is clicked, the computer reverts to the Welcome screen for all users. So we can't perform System File Checker on his login.  What would you suggest?

Yours,

I have run the integrity checker and it says:

"Windows Resource Protection did not find any integrity violations."


I have bitlocker via TPM with PIN setup and secure boot. I did not see these issues prior to setting those up, but that could be a red hearing.
