Disable built-in Visual Studio packages

devenv.pkgundef

//********************************************************//

// HOW TO:
// Create a file called devenv.pkgundef in the same directory as devenv.exe. 
// It's usually located at C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE
// Then call "devenv.exe /updateconfiguration" from an elevated command prompt.

// REMARKS:
// Each GUID below represent a package that Visual Studio is loading. This is the
// list of package that I personally don't ever use. You can modify the list of
// package GUIDs to match yours.

// For full list, see https://github.com/hmemcpy/SlimVS
