Thanks for your help. My Windows 10 is up to date. I'm running IoT Desktop so I guess that's why it doesn't look it. I'm using version 26.1.1 OBS as it's stable for my system. I've tried later versions but OBS thinks it's crashed every time I close it. I may have found a work around using the NDI option for Skype. The only issue is, there's no sign of Skype until a call is made. My system is used remotely by others hence the IoT. I haven't got around to setting my audio up yet, I'll be using Voicemeeter for that. Thanks for the heads up though.
