Which version of Resolve? What OS? What hardware (CPU, GPU, RAM, I/O)? What type of camera source files? What specific kind of rendered file? What resolution are you using?

Windows Media is not always the best choice as a video player. If you install the (free) DHxHD and DHxHR codecs, that can work for a lot of purposes. A lot depends on the needs of your delivered files: for example, you'd want to go in one direction if the final destination was YouTube, and another method if you had to deliver to Netflix or Amazon.

Using Windows 7 instead of 10, perhaps?
