Hi Alexey!

 

Unfortunately, this piling of NLA profiles was solved in WireGuard for Windows 10 only. Windows 7 and 8 will create a new NLA entry each time WireGuard connects.

 

It's the same situation as if you would connect your laptop to 100 or more WiFis in the past.

 

You should address your question why so many NLA profiles crash Task Scheduler to Microsoft.

 

Best regards,

Simon

Subject: Wireguard for Windows breaks Task Scheduler

 

Im not exactly sure what wireguard doing to create virtual network adapters in windows, but it's more looks like it can't handle deletion of them properly. 

This issue easy to reproduce: 

1.	Create wireguard's tunnels.
2.	Connect tunnel, disconnect and remove it.
3.	Repeat it multiple times.

Windows registry will be full of wrong records of these non-existed network connections.

And now try to open Task Scheduler and click on "Create task..." it will crash with log:

 

в Microsoft.Windows.ManagementUI.CombinedControls.INetwork.GetName()
  в Microsoft.Windows.ManagementUI.CombinedControls.UINetwork.GetUINetwork(INetwork network)
  в Microsoft.Windows.ManagementUI.CombinedControls.NetworkListManager.GetNetworkList()
  в Microsoft.Windows.ManagementUI.CombinedControls.ControlTaskConditions.PopulateNetworkComboBox()
  в Microsoft.Windows.ManagementUI.CombinedControls.ControlTaskConditions.InitializeConditions()
  в Microsoft.Windows.ManagementUI.CombinedControls.EditTaskDialog.InitializeView()
  в Microsoft.Windows.ManagementUI.CombinedControls.EditTaskDialog.Initialize(UITaskFolder folder, String taskName, String title, UserChoice userAction, BaseResultsControl inOwnerView, String inXmlText)
  в Microsoft.Windows.ManagementUI.CombinedControls.BaseResultsControl.CreateTask(UITaskFolder folder, String initialTaskName, String taskXml)
  в System.Windows.Forms.MenuItem.OnClick(EventArgs e)
  в System.Windows.Forms.MenuItem.MenuItemData.Execute()
  в System.Windows.Forms.Command.Invoke()
  в System.Windows.Forms.Control.WmCommand(Message& m)
  в System.Windows.Forms.Control.WndProc(Message& m)
  в System.Windows.Forms.ListView.WndProc(Message& m)
  в System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) 

 

So ive googled solution https://answers.microsoft.com/en-us/windows/forum/all/task-scheduler-crashed/5acab7c5-eb79-48c8-876d-ade321565953?auth=1 (Programatix message)

 

To resolve the problem,
    Run regedit
    Go to HKLM\Software\Microsoft\Windows NT\CurrentVersion\NetworkList
    Delete everything under the following path,
        Nla->Cache
        Nla->IntranetEnabled
        Nla->Wireless
        Profiles
        Signatures->Managed
        Signatures->Unmanaged
    Reboot

 

And it actually helps.

Can wireguard just properly handle this "issue" on his own and do not break Task Scheduler application?
