Windows 10 Preview with Cisco AnyConnect VPN Client

Microsoft released the Technical preview of their new Operating Systems. (Details Here) If you are like most IT Professionals, you may have downloaded the preview and try to use it for your basic computing environment. After playing with the new UI for a little bit, I installed the Cisco Anyconnect client and tried to connect to my office VPN. The connection failed with the following error: “Failed to initialized connection subsystem”.

After troubleshooting the issue for a little bit, I found a fix for the issue. Here are the steps to fix your Cisco AnyConnect client running on Windows 10 Preview.

1 . Open and explorer window and go to c:program files (x86)CiscoCisco AnyConnect Secure Mobility Client

2 . Right click vpnui.exe and click properties.

3 . Click the Compatibility tab, then click Run this program in compatibility mode for: and select Windows 8. Then Click OK.

4 . Click the Windows Logo and Click the Cisco AnyConnect Icon.

5 . In the Cisco AnyConnect client type your VPN server FQDN or IP address. Ex:

6. Type your username and password

VPN connect


7. Your client should connect successfully to your Cisco VPN appliance.

8 . After your client finishes the connection you should see a green check mark in the lock.


Hope this helps you test Windows 10 with your corporate images. If you have any questions please leave a comment.

  1. This doesn’t work for me. I’m still getting all sorts of crazy errors. I tried Win 7 compatibility, modifying the settings of ‘vpnagent.exe’, and few other things. The weird part is that sometimes it connects, sometimes it doesn’t. Very sporadic. Let me know if anyone else is having this issue.

  2. That did the trick, works fine ! Hopefully there will be a new version of AnyConnect coming from Cisco in the future to make permanently correct this issue. Thanks!
