How do you fix an unexpected error has occurred?

When you face this error on a Windows system, it often pertains to network-related issues. Here are some steps you can take:

  1. Use Windows’ Network Adapter troubleshooter: This built-in tool can automatically detect and fix common problems with wireless and other network adapters. To access it, simply type “Network troubleshooter” in the Windows search bar and follow the on-screen instructions.
  2. Update network adapter drivers: Outdated drivers can cause incompatibilities. Visit the official website of your computer or motherboard manufacturer to find the latest drivers.
  3. Remove and reinstall adapter drivers: Sometimes, merely updating the driver isn’t enough. In these cases, completely uninstalling and then reinstalling the driver can solve the problem.
  4. Turn off IPv6 for your adapter: Some networks might face issues with IPv6. To disable it, go to Network and Sharing Center, click on your connection, choose Properties, and then uncheck the IPv6 box.
  5. Re-register the “netshell.dll” file: This dynamic link library file is crucial for network operations. Use the Command Prompt to re-register it by typing “regsvr32 netshell.dll”.

Tackling Instagram’s Unexpected Errors

Instagram, like many other apps, is not immune to glitches. Here’s how to address unexpected errors specifically within the Instagram platform:

  1. Understanding the error: Temporary glitches in the system can trigger the “unexpected error” message. A simple page refresh often resolves this.
  2. Clearing app cache and data: Over time, app cache and data might get corrupted, leading to various errors. To clear it:
  3. Go to your device settings.
  4. Navigate to Apps or Application Manager.
  5. Find and select Instagram.
  6. Tap on “Clear Cache” and “Clear Data”.


What causes the “unexpected error” message in general?

Can restarting the device help in resolving unexpected errors?

Yes, often a simple restart can clear out minor bugs and glitches causing the error.

Is it safe to clear cache and data for apps?

Clearing cache is generally safe and can free up memory. However, clearing data might reset app settings to default and remove saved information within the app. Always backup important data before clearing it.

How often should drivers be updated?

While there’s no fixed frequency, it’s good practice to check for driver updates every few months or when facing system performance issues.

Do unexpected errors pose a threat to my device or data?

Not necessarily. While they indicate a problem, most unexpected errors are benign. However, regularly backing up data is always recommended.
