David Plummer, the former Microsoft developer who wrote Windows Task Manager in the 1990s, has revealed the application’s inner workings and hidden tricks.
Windows Task Manager (TaskMgr) first shipped with Windows NT 4.0 in 1996, and anyone who’s used Windows since then has probably used the app to check CPU load or to kill a process.
As Plummer details in a post on Reddit, while working as a new developer at Microsoft’s Redmond headquarters, he wrote Task Manager “at home in my in my den” around 1994.
