This may not be very useful for end users, but for VSX developers it allows you to test your extension (which needs to declare the minimum supported edition in the Vsix manifest) on the three editions on the same computer. So, you can have VS 2017 Community Edition, VS 2017 Professional Edition and VS 2017 Enterprise Edition.

Visual Studio 2017 allows to coexist several editions on the same machine.For VSX developers like me that already have six versions of Visual Studio installed (from VS 2005 to VS 2015) on the main dev machine (not counting isolated installations on virtual machines) and know how painful each installation is, this is big news. This suggestion had almost 2,000 votes on UserVoice. The consequence is that installing VS 2017 is much, much faster (unless you install a lot of workloads, of course). It provides a new modular setup that allows you to decide which tools (“workloads”) you want to install and, most importantly, which ones you don’t want at all.As you may already know, VS 2017 (formerly VS “15”) introduces a couple of very welcomed changes:
