Microsoft announced this week that they will be relaunching the Windows PowerToys for Windows. The tools were small freeware utilities that were created by Windows developers as side projects related to something that they were interested about. They were not supported by Microsoft and were use-at-your-own-risk type of tools. They allowed you to play with Windows internals by tweaking undocumented features, play with fun tools, or to provide functionality that made it easier to get things done. Microsoft is also considering other tools to be added.
