I have followed both infected_Post’s and Snake_Pliskin’s advice, including restart after uninstalling and running the VisualStudioInstaller. When I reinstall, it looks like only Update 2 will be installed… But ultimately, when I start up, I see in VS About/Help that it is still Version 14.0.25420.01 Update 3.
Update 3 keeps sneaking in! Any ideas what I am doing wrong?
