The short answer is it doesn't. In Windows the OS provides an API for colour management only. It's up the to the application to request windows to provide it the current display profile. It's up to the application to convert the profiles or to make a call to WCM to convert the profiles on it's behalf. And then the application hands the data to the video card which faithfully sends the data to the monitor unless the lookup table has something so say about it.
The video card lookup table should universally never be able used for colour space conversion as any deviations from the standard curve cause a loss of quality. It's only used for ensuring that response follows the correct curve without a colour shift throughout the range of tones and actual colour management itself is managed by ... well ... colour management.
In the windows world colour management is one ugly steaming turd.
