How do I use it?
I copied wkForceFrontendResolution1680x1050.dll into my WA folder and all it does is crash the game right after running.
These modules aren't really for a stable use - they force the desired resolution in the frontend, making it in the top left corner if it's bigger. They also minimize the game on the start.
As about crashing the game - make sure that the resolution you selected is supported by your graphics card. Mine supports from 320x200 to 1366x768
