Keep Windows awake for a long task with PowerToys Awake

A long download, file copy or video export can run longer than Windows’ idle sleep timer. For a one-off job, PowerToys Awake can ask Windows to stay awake for a set interval without changing your saved power plan. The useful combination is a timed interval plus a display setting chosen separately.

This guide reflects PowerToys 0.93.0, released on 13 August 2025, and Microsoft’s Awake documentation dated 20 August 2025. The steps are documentation-based: they explain the controls and their limits, not a guaranteed finish time for any particular app or connection.

Is PowerToys Awake the right fit?

Awake is useful when you need a Windows task to continue while you remain signed in. Choose Keep awake for a time interval for a bounded job. The interval expires automatically and Awake returns to a disabled state, leaving the normal Windows power plan in effect.

The display is a separate choice. By default, the screen can turn off while the PC stays awake. Turn on Keep screen on only when you need the desktop visible, such as during a presentation or when you must watch progress.

There is an important limit in Microsoft’s August 2025 guidance: Awake does not function when the lock screen is displayed. It is therefore not the right tool for a job that must keep running on a locked PC. For that situation, use Windows power settings directly and consider the security implications of leaving a device unattended.

Set a timed keep-awake interval

1. Open PowerToys Settings. If PowerToys is not installed, use Microsoft’s PowerToys 0.93.0 release page ; choose the installer for your PC and installation scope.
2. Select Awake in Settings and turn on Enable Awake.
3. Choose Keep awake for a time interval and set a duration a little longer than the task is expected to take. For example, if a file export is expected to take 90 minutes, a two-hour interval leaves a 30-minute margin. That is a planning example, not a promise that the export will finish.
4. Leave Keep screen on off for a background task. Enable it only if you need the display to remain visible; it is not required just to keep the PC awake.
5. Check the Awake tray icon and its tooltip for the timed state, then start the task. Set the interval first: changing its hours or minutes resets the timer from the latest input.

Let the normal power plan take over

When the interval expires, Awake returns to its disabled state and the PC resumes its normal power-plan behaviour. If the task finishes early, turn Awake off in Settings instead of leaving an unnecessary request active. If it is still running near the end of the interval, check the app’s own progress before extending the timer.

Awake controls Windows’ idle power behaviour; it does not keep an app from crashing, restore a lost network connection or prevent you from manually putting the PC to sleep or hibernating it. If Windows still sleeps, confirm that Awake is enabled, the tray icon shows a timed mode and the interval has not expired. Also check that the lock screen is not displayed.

Use a timed request for a task with a reasonable end point. For a persistent power rule, or a task that has to continue while the PC is locked, consult Microsoft’s PowerToys Awake documentation and configure Windows’ own power settings instead.
