Eclipse freezes on Windows 10 creator’s update

Symptoms: Eclipse used to work fine under Windows 10, suddenly hangs short after start.

Solution: uninstall Linux subsystem or don’t use Git in Eclipse

Explanation: the Eclipse egit plugin looks for bash, which normally doesn’t exist on Windows. When the Windows subsystem for Linux is installed, bash does exist, but blocks with a message (“click to continue”). You need to get rid of that message; uninstalling the Linux subsystem is one way.
