To solve this problem, we have shared some ways that can help you get rid of this error.

Fix ‘An Unexpected Network Error Occurred’ Problem in Windows

Disable Third Party/antivirus or firewall

Security programs on your PC often cause problems with new updates. Antivirus programs cannot detect “good” and “bad” uses of these applications, so they may warn you about blocking or even removing them.

In most cases, you can disable the antivirus by looking for it in the right corner of the taskbar. After finding your antivirus icon, right click on it. You should get a dropdown menu and click Disable. This will disable your antivirus while you work on installing the new updates.

If you don’t want to disable it and you don’t want to have this problem again in the future, the best thing to do is to make an exception in your antivirus settings so that there are no problems in the future. In most cases, you can make an exception by going to your antivirus settings, looking for exceptions, and adding a rule. If you get stuck, visit the website of your specific antivirus and find a detailed guide on how to do the two things above. To disable the firewall, follow the steps below.

  • Open Control Panel by going to the Start menu and locating All Programs. Navigate to the Control Panel icon and click on it.
  • In Control Panel, click the System and Security icon.
  • Click Windows Firewall.
  • If Windows Firewall is disabled, the Windows Firewall status will be Off. If it is enabled, you need to disable it.
  • In the Customize settings window, select Turn off Windows Firewall and click OK.

check the format

Windows and your storage have a few different formatting methods such as: B. FAT32 or NTFS. Both methods have different limitations and some of them can cause this problem. What you need to check is the format of the destination drive you are copying the file to. If it’s FAT32, you should know that it only supports files smaller than 4 GB and automatically locks itself towards the end of the copy.

This only happens with a single file larger than 4GB. So if it’s a lot of smaller ones, you should be absolutely fine. Although this sounds like a much more complicated problem than it really is, just follow the methods above and you should be absolutely fine.

Enabling guest access using Windows Powershell

Changing this value will enable guest access on your Windows which can potentially fix this 0x8007003B error. You have to edit the key using Registry Editor, but I’ve created this command that will do the same thing but you won’t have to go through any hassle of editing the registry. To enable guest access, follow the steps below.

  • Right-click the Start button and press “Windows Powershell (Admin)”
  • Put the following command and press enter.
    • REG ADD HKLMSYSTEMCurrentControlSetServicesLanmanWorkstationParameters /f /v AllowInsecureG
  • Reboot your computer and your issue should be resolved.
