VSWhere utility for locating installations

If you have multiple versions of Visual Studio or Build Tools installed on your PC, you can quickly find them with a small command-line utility called VSWhere.exe. It's included with Visual Studio 2017 under the installation path at:

C:\Program Files (x86)\Microsoft Visual Studio\Installer\vswhere.exe

When you run it, it will list all installed editions, something like this:

instanceId: 6b05f542
installDate: 20.2.2018 13.28.07
installationName: VisualStudio/15.0.3+26228.04
installationPath: C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise
installationVersion: 15.0.26228.04
productId: Microsoft.VisualStudio.Product.Enterprise
productPath: C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\devenv.exe
isComplete: 1
isLaunchable: 1
...

You can even use command-line switches to filter or format the results:

vswhere -latest -products * -requires Microsoft.Component.MSBuild -property installationPath

The above command returns the latest Visual Studio installation path with MSBuild installed. This can be useful for scripts and build servers.
