So the result of using these types of tools in some cases may lead to failure of the login process. In this article, we are going to talk about the Sign-in process initialization failure error. That results after using third-party software on Windows 10 running machine actually.

Restore Missing LogonUI File
LogonUI file or application basically sits in System32 folder under your Windows directory aka %WinDir% folder. If a third-party tool actually modifies this application, renames it, or also erases it. The above-mentioned error may occur. So our aim here is just to restore this file to its original identity actually.
How do I find that LogonUI is missing or renamed? | sign in process initialization failure
If you guys are on a dual boot system, then locating LogonUI is pretty easy. You guys can boot to another OS and via File Explorer and then browse to %WinDir% of the problematic OS. However, for a machine along with a single OS, you just have to install a new OS on a parallel drive, so that result is a dual boot system as well. You guys can then verify the status of the LogonUI file using the same approach mentioned for the dual-boot system. If it is missing, then you need to copy it from the new OS., (Must be the same edition and architecture) that you just install, to the old OS along with the issue.
If you guys can locate the LogonUI file along with a different name, then here is how you can restore its original name:
- First of all, just open Command Prompt at boot in the problematic OS, from the Advanced Recovery Options.
- The type following commands and click on Enter after each of them:
cd <system drive>
ren <old LogonUI file name> LogonUI.exe
- Continue to your OS on the next screen or restart it as well. After you reboot, you will be able to log in normally – as expected as well.
