| If it's in \windows\System32 it's the Welcome Screen Logon Service, if it's in another directory is probably a malware! Usually, in a windows session LogonUI.exe is not active... Framp | |
| There are malware using this filename, but if it is not detected by antivirus it's probably just windows logon screen which is safe. File should be in windows\system32 if safe. See also: Link Johnny | |

| welcomes screen for windows NT (xp for example). it is also used when shutting down the computer. Devoney | |
| UI stands for user interface. In electronic terms, this means "what you see". It is also known as GUI (the G being Graphic(al), which means it has more than just text (the terms are now interchangeable unless you do not use Windows.). Normally, you will see this program running if you have your OS (NT-Based [XP]) set to be able to see the log-in screen. I have mine disabled, since I like to be able to press my power button and see my desktop in 3 seconds. It will probably run, reguardless, if you attempt to change users/accounts. Skylor Wold | |

| People must remember that there IS a legit file with this name. So if you find it to be suspicious or your anti virus is saying its infected then its another file with that FILENAME. Viruses usually use a filename that sounds safe or sounds like a system operating file. This is to confuse you. The reason being to confuse is to stay running knowing you wont delete a system file (if you do your fried) That being because the real file lies within system32 folder. A culprit with exact name file will more than likely linger in a folder on your users account Shibbee | |

| I cant even get past the start up screen. It says diagnosing disk, then it says: repairing disk errors. This might take over an hour. And it does that every time without showing my screen and if it does it freezes after 2 minutes! Please tell me how to fix this because I haven't downloaded anything and then that happened. Then it says file 00000001 is not in your computer, click to terminate. Lolorous | |
