PowerToys Awake is not the only addition coming soon to PowerToys. Here is how PowerToys Awake settings UI looks like (disregard the early Espresso name.) While primary controls for PowerToys Awake will live in the app's main window, developers consider adding additional tools, such as a system tray icon and a external command line interface. When PowerToys 0.39 arrives, you will have an option to disable sleep mode in Windows 10 indefinitely or set a specific period, for example, stay awake for 5 hours. What makes PowerToys Awake more appealing is that it comes from Microsoft, and it is open-source. After all, you can use Power Settings in Windows 10 to disable automatic sleep mode. There are several third-party alternatives for preventing Windows from entering sleep mode.
PowerToys Awake is not something new to Windows users.
