I have started a new desktop build recently. As part of this I want to make the user experience the cleanest possible. One of my pet hates is the Lync Browser Helper Addon. Even if you enable it, it disables itself as its not compatible with browsers in Windows 10. Use the registry key below to remove the nag for users.
If you want to roll it out to lots of users then you can use Group Policy Preferences. You can use my guide at the link below if you want to find out how to do it.
