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.
