separately to compile drivers. From the version for Windows XP the DDK and later the WDK include a command-line compiler to compile drivers. One of the reasons Microsoft gave for including a compiler was that the quality of drivers would improve if they were compiled with the same version of the compiler that was used to compile Windows itself while Visual C++ is targeted to application development and has a different product cycle with more frequent changes. The WDK 8.x and later series goes back to require installing a matched version of

separately, but this time the integration is more complete in that you can edit, build and debug the driver from within Visual Studio directly.
