Welcome to SF!

Two of them appear to be caused by your VPN Client. I suggest uninstalling it, and see what happens.

The other two them look like they were caused by a Windows service being force ended. If you didn't manually end them in Task Manager, check for viruses using Malwarebytes.

Please post any new dmp files you might get. See this tutorial:

Use !analyze -v to get detailed debugging information.

That definitely gives a lot of insight. You're right! I never had issues before I installed the VPN client. Do you know any other VPN clients that would work on win7 x64?

Thanks again,
