This week, Avram Piltch shows you how to enable Dark Mode across a variety of platforms on your PC. The feature has come out of the darkness in the past year, with many developers building the feature into their software, even on the web. Windows has supported the feature since Windows Phone 7 and Windows 8, but the capability is gaining wide adoption now. Luckily, Avram's got the process for Windows, Skype, Microsoft Word and more.
