PowerToys – open-source Windows utilities
PowerToys Run is fantastic as an app launcher. Not quite as good as Alfred on MacOS but then nothing is. There's a bunch of similar apps for Windows (I used to use Hain) but none ever worked quite right for me, PowerToys Run does though.<p>FancyZones is awfully nice too for just putting a window somewhere at a reasonable size and location.<p>As other folks have noted SysInternals is another similar rogue Windows product by Microsoft. Process Explorer from there is indispensible, as is Autoruns.
