The “REF_UNKNOWN_LOGON_SESSION” Blue Screen of Death error (0x00000047) is a critical error typically related to the security mechanisms in your operating system. This error generally indicates that a reference was made to a logon session that does not exist. Similar to the “DEREF_UNKNOWN_LOGON_SESSION” error, it can be caused by problematic security software or corrupted system files.

How to fix:

  1. Inspect Your Security Software: Security software that’s not functioning correctly can often cause this type of error. Try temporarily disabling or uninstalling any recently installed or updated security software to see if the error persists. Be sure to reinstall it or replace it with a different security solution as soon as possible to ensure your system remains secure.
  2. Update Your Operating System: Make sure that your operating system is up-to-date. Microsoft regularly releases patches and updates to address bugs and security issues, and one of these updates might resolve your issue.
  3. System Restore: If the problem started appearing recently, you might consider using a system restore point to return your system to a state from before the issue began.
  4. Run System File Checker (SFC): System File Checker is a tool included with Windows that allows you to scan for and restore corrupted system files. You can run it by opening Command Prompt as an administrator, typing sfc /scannow, and pressing Enter. SFC will then begin a scan and attempt to repair any issues it finds.
  5. Check for Disk Errors: You can check your hard disk for errors by opening Command Prompt as an administrator, typing chkdsk /f /r, and pressing Enter. If your disk is currently in use, you might need to schedule this operation to run the next time your system restarts.
  6. Inspect Your Hardware: Hardware issues, such as a failing hard drive, can sometimes cause BSOD errors. If you’ve recently added new hardware to your system, it could be causing this error.

Remember, if these steps don’t resolve the issue, it might be best to seek professional help or reach out to Microsoft Support. Errors like this can sometimes be due to deeper, more complex issues that require expert assistance to diagnose and resolve.
