Hundreds of linker errors not even related to my program.

Okay, since microsoft loves messing things up and intruding on people, maybe you can fix this mess from your VS. I have hundreds of linker errors suddenly start appearing from a development that was working fine until I decided to include a dropdown box. None of them have anything to do with what I am doing, I have even removed the headers from the file and now I just can not compile my program because of these stupid errors. I have tried to set the hardware identifier in the properties and hardcoded in #pragma. I have already started to convert the whole program to a non windows console and frankly at this point, I am seriously considering just migrating all my OS to linux. And before you ask, no, you are not having my code.
