I use a program called Redshift, an alternative to this application as its not available on windows is somethibg called f.lux. It could be worth a look, but I have not personally tried f.lux so I cannot attest to it, but it was recomended as a windows alternative to Redshift.

As with anything do a little research before installing any application, make sure its conpatible with your system and that the program developers are up to date with their application. hope this helps
