Microsoft PowerToys also contain a new neat launcher called "PowerToys Run" which is similar to Launchy. It supports various plugins including Calculator. I like the feature that it shows up on the display where the mouse pointer is currently located so you don't have to jump between displays.

Love powertoys. I started using it for being able to define screen areas to snap windows to "FancyZones" but once I started using PowerToys Run, I was hooked. I almost never use the start bar (or calculator) anymore. In addition to starting your apps, it also can do calculations, execute shell commans, web searches, find open windows, etc.

It also include a mouse / click highlighter that's helpful when you're recording a training / onscreen presentation.
