How to Fix the Event ID 1796 TPM-WMI Error - Full Guide

This guide provides solutions for the Event ID 1796 TPM-WMI error, which can cause system crashes, freezes, and blue screen errors (BSOD). This error often manifests as a "Secure Boot update failed" message.

Understanding the Error

Event ID 1796 indicates a problem with the Trusted Platform Module (TPM) and Windows Management Instrumentation (WMI) during a Secure Boot update. This typically occurs during system startup, application launch, or while gaming.

Troubleshooting Steps

Several methods can resolve this issue:

Method 1: Toggle Secure Boot

Secure Boot enhances system security. Temporarily disabling and re-enabling it can sometimes resolve conflicts.

1. Access your BIOS settings during startup (usually by pressing keys like F2, Del, or others, depending on your motherboard). See our guide on how to access BIOS for more details.
2. Navigate to the Security section and find the Secure Boot option.
3. Disable Secure Boot, save changes, and restart.
4. Repeat steps 1-3, but this time enable Secure Boot.

Method 2: Uninstall Recent Updates

A recent Windows update might be the culprit.

1. Open Windows Settings (Start Menu > Settings).
2. Go to Update & Security > Windows Update.
3. Select View update history.
4. Click Uninstall updates.
5. Right-click the most recent update and choose Uninstall.

Method 3: Reinstall Problematic Applications

If the error occurs when using a specific program, reinstalling it may fix the problem.

1. Open Settings > Apps > Apps & features.
2. Find the suspect application, click it, and select Uninstall.
3. Reinstall the application from the official source.

Method 4: Reset or Update BIOS

A BIOS reset or update can sometimes resolve underlying hardware conflicts.

• BIOS Reset: Access BIOS settings (as in Method 1), locate the option to reset to factory defaults (e.g., Load Default Settings), and follow the on-screen instructions.
• BIOS Update: This is more advanced. Always back up your data first. Find the latest BIOS update for your motherboard model on the manufacturer's website, download it, and follow the manufacturer's instructions carefully. Incorrectly flashing your BIOS can severely damage your system.

Data Backup Recommendation

Since this error can lead to data loss, using backup software like MiniTool ShadowMaker is highly recommended. It offers system backups, file and folder backups, and scheduled backups for comprehensive data protection.

Conclusion

These methods offer various approaches to resolving the Event ID 1796 TPM-WMI error. Try each method sequentially until the issue is resolved. Remember to always back up your important data before making significant system changes.
