The presence of VPN solutions in the current state of computing technologies reached its peak. And since Windows 10 is one of the most used operative systems, a large chunk of the Virtual Private Networks run on Microsoft’s latest iteration. Although they mostly work well, there are certain issues, especially after the major Windows Updates, like Creators Update and Fall Creators Update.

These issues are quite common after every new major release and we decided to provide you with the list of possible solutions which should help you address them. If you’re suddenly stroke with a plethora of VPN issues after a Windows update, make sure to check them out below.

How to fix Windows 10 VPN issues which occurred after updates

  1. Update Windows 10 again
  2. Reinstall drivers
  3. Edit registry
  4. Reinstall VPN
  5. Disable antivirus
  6. Disable IPv6
  7. Troubleshoot connection
  8. Reset your PC to factory settings

1: Update Windows 10

It seems that the Windows 10 Updates function, more or less, in the same sequence. Microsoft provides a major update in order to bring improvements, a large variety of bugs appear, and they then, overwhelmed by the large community backlash, end up pushing appropriate fixes as soon as possible. That’s how it basically works. Since this is a widespread problem and it mostly occurred after the Windows Creators Update and Fall Creators Update, they provided the resolution soon.

A lot of users which experienced issues with VPN after an update, get things sorted out after some time by updating Windows 10. So, make sure that you have all available updates installed and try running VPN again. In case you’re unable to make it work regardless, make sure to move to alternative steps.

Here’s how to check for available updates in Windows 10:

  1. Press Windows key + I to summon the Settings app.windows 10 vpn not working after update
  2. Select Updates & Security.
  3. Select Windows Update from the left pane.
  4. Click on the ”Check for updates” button.windows 10 vpn not working after update

In order to avoid these issues and errors, we strongly recommend choosing a reliable and compatible VPN. Get now CyberGhost VPN (currently 77% off) and secure your network without errors. 


2: Reinstall drivers

Certain users resolved the issue by completely uninstalling all Network adapters, but you can specify on reinstalling WAN Miniport drivers. Either way, we all know how notoriously Windows 10 manages drivers and how the generic and mandatory drivers can have an illicit effect on system performance and stability.

In order to avoid this, you can reinstall drivers changed by the last update and let them reinstall on their own. Also, secondary drivers provided by a third-party VPN are better than the ones Windows Update provides. So, you can also uninstall them and VPN, and then just obtain them by reinstalling VPN from a scratch.

Here’s how to reinstall WAN Miniport network drivers in Windows 10:

  1. Right-click on Start and select Device Manager from the PowerUser menu.windows 10 vpn not working after update
  2. Expand the Network adapters section.
  3. Right-click on every individual WAN Miniport driver and uninstall it.windows 10 vpn not working after update
  4. Restart your PC and open Device Manager again.
  5. Navigate to Network Adapters, right-click every individual Miniport and install it.
  6. Try running VPN again.

Update drivers automatically (suggested)

After you have uninstalled your drivers, we recommend to reinstall/update them automatically. Downloading and installing drivers manually is a process that carries the risk of getting the wrong driver installed, which may lead to serious malfunctions of your system.

The safer and easier way to update drivers on a Windows computer is by using an automatic tool. We strongly recommend Tweakbit’s Driver Updater tool. It automatically identifies each device on your computer and matches it with the latest driver versions from an extensive online database.

Here is how it works:

    1. Download and install TweakBit Driver Updaterdriver updater starting window
    2. Once installed, the program will start scanning your PC for outdated drivers automatically. Driver Updater will check your installed driver versions against its cloud database of the latest versions and recommend proper updates. All you need to do is wait for the scan to complete.

    3. Upon scan completion, you get a report on all problem drivers found on your PC. Review the list and see if you want to update each driver individually or all at once. To update one driver at a time, click the ‘Update driver’ link next to the driver name. Or simply click the ‘Update all’ button at the bottom to automatically install all recommended updates.

      Note: Some drivers need to be installed in multiple steps so you will have to hit the ‘Update’ button several times until all of its components are installed.

Disclaimer: some features of this tool are not free.

3: Edit registry

As some tech-savvy users noted, this error can have roots in the PolicyEditor. This is the main part of the Windows platform and it regulates the security and access policy for all individual users on one machine. In order to address this possible instigator of the problem with VPN, we’ll need to change the policy settings by inserting an exception for UDP. Now, the best way to do so is to use Registry Editor. Of course, with this tool we’re roaming in the dangerous area, so make sure to act with caution and don’t delete anything while there.

Follow these instructions to access Registry Editor and create a new input which should re-enable VPN in Windows 10:

    1. In the Windows Search bar, type regedit and open regedit from the list of the results.windows 10 vpn not working after update
    2. Backup your registry.
    3. Navigate to this location:
      • Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PolicyAgent
    4. Right-click on the blank area in the right window and select New > DWORD.
    5. Name the new DWORD input AssumeUDPEncapsulationContextOnSendRule.windows 10 vpn not working after update
    6. Change its value to 2 and save it.
    7. Close Registry Editor and restart your PC.

4: Reinstall VPN

Since the update-inflicted issues can affect both third-party VPNs and built-in Windows VPN, respectively, we decided to cover both. Regarding the former, if you’re sure that everything was bread and butter before the update and then the things suddenly went south, we advise you to reinstall the client you use.

Reinstallation is also the re-integration of the VPN into changed system surroundings, so this just might help. Also, while we’re at it, don’t forget to acquire the latest version of your VPN of choice. We make sure to showcase the whole procedure, and decided to use TunnelBearVPN as the example, but this applies to all VPN solutions in general. Make sure to follow the instructions we provided below:

  1. In the Windows Search bar, type Control and open Control Panel from the list of results.windows 10 vpn not working after update

  2. For various PC problems, we recommend this tool.

  3. From the Category view, click Uninstall a program under Programs.windows 10 vpn not working after update
  4. Right-click on your VPN solution and Uninstall it.windows 10 vpn not working after update
  5. Use IObit Uninstaller Pro (suggested) or any other third-party uninstaller to clean all remaining files and registry entries the VPN has made.
  6. Restart your PC.
  7. Download the latest version of the VPN of your choice (CyberGhostVPN is our choice) and install it.

5: Disable antivirus

Another possible reason for this error can lie in the third-party antivirus or some of its subsidiaries. Contemporary antivirus solutions often come in suits which include third-party Firewall security measures. They do come in handy, especially if you’re knowledgeable enough to customize them, but are, on the other hand, known for conflicting with Windows services.

If you run VPN through Windows 10 VPN provided by Microsoft, make sure to disable the third-party firewall before doing so. Or even better, for the sake of troubleshooting, disable the antivirus completely and move from there.

Also, make sure that your native Windows Firewall isn’t preventing VPN from accessing the remote servers. Here’s how to add an exception to Windows Firewall in a few simple steps:

  1. In the Windows Search bar, type Allow and select ”Allow an app through Windows Firewall”.windows 10 vpn not working after update
  2. Click on the ”Change settings button”.
  3. Find your VPN on the list and check the box beside it. Also, make sure that both Public and Private networks are enabled.windows 10 vpn not working after update
  4. Confirm changes and try connecting through VPN again.

6: Disable IPv6

Connection issues, with or without VPN, are rather common after every new major update. Major updates tend to make certain changes to your adapter settings, making it unusable in the process.

Now, in step 7 we’ll try to address all-around connection settings, but this step concerns only IPv6. Namely, for users with the older configuration, the problem might occur due to conflict with the Internet Protocol. The most users who found this step helpful disabled IPv6, but you can try disabling IPv4 and stick with IPv6, too.

If you’re not sure how to disable IPv6 (or IPv4, its older variation), follow the steps below:

  1. Type Control in the Windows Search bar and open Control Panel from the list of results.windows 10 vpn not working after update
  2. Open Network and Internet and then Network and Sharing Center.windows 10 vpn not working after update
  3. Select ”Change adapter settings” from the left pane.windows 10 vpn not working after update
  4. Right-click on VPN network adapter and open Properties.windows 10 vpn not working after update
  5. Uncheck the box beside IPv6 and confirm changes.windows 10 vpn not working after update
  6. Try running VPN afterward.

7: Troubleshoot connection

We don’t want to point fingers towards the VPN until we eliminate all possible connection issues. In other words, make sure that you can connect without VPN in the first place. If that’s not the case, we advise you to perform standard troubleshooting steps and move from there.

If you’re caught in the middle and unsure what to do, here are some actions that you should consider:

  • Reset your router and/or modem.
  • Flush DNS.
  • Restart related services.
  • Run dedicated Connection troubleshooter.
  • Disable router’s firewall.
  • Update router’s firmware.
  • Reset router/modem to factory settings.

8: Reset your PC to factory settings

Finally, if none of the solutions proved helpful, we recommend resetting your PC to its factory values. We’re well aware that this is far from the desired outcome, but if you’re out of the cards to play and heavily relying on VPN, this solution might not be as ludicrous as it initially sounds.

Just, before doing, so make sure to backup all your data from the system partition to the data partition, external hard drive, or cloud service of choice. If you’re not sure how to reset your Windows 10 machine to default values and refresh it in the process, follow the instructions we provided below:

  1. In the Windows Search bar, type Recovery and open Recovery options.windows 10 vpn not working after update
  2. Under the ”Reset this PC” section, click on the ”Get started” button.windows 10 vpn not working after update
  3. Select whether you’ll preserve or delete your files from the system partition and click Next.
  4. Follow the instructions until the system is fully restored to factory values.windows 10 vpn not working after update
  5. Install VPN again and the update-inflicted problem should be gone.

This should conclude it. In case you’re still unable to use your VPN on Windows 10 after an update, make sure to send a ticket to both Microsoft and your VPN provider. Also, if you’re having issues with the business network, contact your network administrator. At least one should give you the helping hand, and chances are that the paid VPN service provider will be the one. Either way, make sure to tell us if you have an alternative solution or a question regarding the ones we provided above. You can do so in the comments section below.
