I have a fresh(3 days) 15063.502 build(version 1703)installation of win10 pro x64. After a long session in which i changed various windows settings, i restarted and my mouse speed is the double than before. I droped two notches the mouse speed setting from the Windows control panel and the situation is a bit better but not satisfactory. I always use default mouse speed and i never had a similar issue. Any ideas on what can altered my mouse speed ?
