I've been working on my game engine for a while and for some reason all of a sudden I came up with an error that many header files are missing. I checked the console and there is no errors in the code and also I already compiled the project before. It happened after I removed Windows files from my old disc that I dont use as primary disc anymore and visual studio mightve used those files from that path. I already tried repairing Visual Studio but it didn't fix the problem. Here is a screenshot of the errors:
ANSWER: The Windows SDK was missing and so, the files couldn't be found. I downloaded the sdk from here
