How do I disable VsHub.exe in the system tray?

Question

Starting Visual Studio 2015 also launches two other executables:

VsHub.exe

and

Microsoft.VsHub.Server.HttpHost.exe<

Answer 1

According to a Microsoft Program Manager commenting on the Visual Studio Blog commenting on the Visual Studio Blog, it's used to support multi-tool communication across the VS suite. Given how complicated Visual Studio is, I wouldn't recommend anything as harsh as xakepp35's answer (deleting it).

On my Win10 x64 with VS2015 running, while debugging, there's three processes and the total RAM usage is less than 150MB total. Unless you're page-thrashing on a machine with minimal RAM that's not much to be concerned about. Given that you're running VS2015, I'd guess you have 150MB to spare.

Until or unless you find documentation showing explicitly what the Hub is supporting, I'd recommend leaving it be. In my experience, Visual Studio installs are far too easy to break.
