Follow these steps to run these commands:

  1. If Windows is booting normally on your device, launch the Command Prompt or Terminal with the administrator rights and switch to step 4. If you’re unable to boot Windows, restart it several times to launch the Automatic Repair Mode and follow the further steps.
  2. Choose the Troubleshoot option.troubleshoot option

The SMSS.EXE file is crucial for session management. Sometimes, third-party antiviruses might flag it as malware and delete or quarantine it, causing the 0x0000006F SESSION3_INITIALIZATION_FAILED error.

If the corrupted or deleted SMSS.EXE file is causing the issue, manually replacing it can resolve it. This process involves using the Command Prompt and navigating to the system32 directory to replace the file.
