The Tailscale service doesn’t start for some Windows users. Logs:

The Error listing NDIS interfaces is from:

https://github.com/tailscale/wireguard-go/blob/main/tun/wintun/wintun_windows.go

// handle returns a handle to the interface device object.                                                                                                                                  
func (wintun *Interface) handle() (windows.Handle, error) {
        interfaces, err := setupapi.CM_Get_Device_Interface_List(wintun.devInstanceID, &deviceInterfaceNetGUID, setupapi.CM_GET_DEVICE_INTERFACE_LIST_PRESENT)
        if err != nil {
                return windows.InvalidHandle, fmt.Errorf("Error listing NDIS interfaces: %v", err)
        }

Which calls this, which returns the no interfaces found:

https://github.com/tailscale/wireguard-go/blob/de1f1af1f35f0892b833a64c7080b265d18cf17a/tun/wintun/setupapi/setupapi_windows.go#L503

...
	if interfaces == nil {
		return nil, fmt.Errorf("no interfaces found")
	}

So I finally managed to try out a new build, sadly:

---------------------------
Error
---------------------------
Tailscale backend error:

wgengine.NewUserspaceEngine: Error creating interface: GetStringValueWait(NetCfgInstanceId) failed: Timeout waiting for registry value

logid: 55d55dd3266d215e76e49ccf84464f5e47405e678e031a8994008d19a3f35385

---------------------------
OK   
---------------------------

However, on another machine that is running a different Windows build (and didn’t have tailscale installed), not such errors.

Working Windows Version: 10.0.20175 Build 20175 (Insider Preview) Failing Windows Version: 10.0.19042 Build 19042

Thanks.

BTW, little known Windows trick: you can focus those message box dialogs and hit Control-C and even though the text can’t be selected, that Control-C should make a sound and copy the full text to your clipboard which you can paste in here.
