How to fix Windows 7 Interactive logon process initialization has failed error

Recently ran into an issue where a Windows 7 system for no reason gave a “Interactive logon process initialization has failed” error for no reason. No updates had been applied and nothing out of the ordinary.This is a quick post on how I was able to resolve the issue.

Tried several of the usual steps.

  • Reboot the system
  • Tried to select Safe Mode, does not work same error
  • Last Known Good Configuration

None changed the error and could not get past the error. Booted from a Linux live CD (Fedora 22) and started looking around in the filesystem and found the c:\Windows\system32\logonui.exe file was missing. Copied the file from another working Windows 7 instance to a USB flash drive and copied to the systems directory. After rebooting the error was gone.

    Worked for me, although c:\Windows\system32\logonui.exe was present I copied over the file from a working PC rebooted and it worked fine. Booted my PC with BART PE bootable CD and copied file from USB stick.
