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.
