Shutdown Scheduler turns your PC off at a set time, every night or just once, so the BIOS timer can bring it back in the morning. The window always shows what is really set.
The exe isn't code-signed, so Windows may warn you the first time. Choose More info, then Run anyway.
Shutdown Scheduler
Set it once. Shutdown Scheduler stores the schedule in Windows itself, warns you before it acts, and tells you how last night went.
Type the time (0230, or 2 then Enter for 02:00), scroll over it, use the arrow keys, click − 15 or + 15, or pick a preset. Choose Every night or Just once, then click the wide button at the bottom.
While a schedule is on, changes save straight away. You can close the window and the schedule stays set, including across restarts.
Shutdown Scheduler
Five minutes before the shutdown, a countdown appears in the bottom right corner without taking focus from what you are doing. It offers + 30 min, Skip this one and Shut down now.
When it ends, if you used the keyboard or mouse in the last 5 minutes, the shutdown waits 30 minutes and the countdown comes back, up to 3 times. After that, or if the PC isn't being used, the PC shuts down and open apps close without saving.
Skip tonight leaves every other night alone, and Don't skip it undoes it. Turn off stops the schedule altogether.
The line at the top always says what will happen next. It turns amber when a night is skipped or postponed, so you can tell at a glance that the PC won't go off when you expect.
Shutdown Scheduler
A shutdown at 02:00 is only useful if the PC comes back properly at 07:00.
It shuts down with shutdown /sg, so Windows signs back in and locks after the BIOS timer starts the PC, the same as shutting down from the Start menu. Plain /s leaves the PC at the sign-in screen with none of your startup apps running.
A line above the version shows when the PC went off, came back and signed in. It warns you if a shutdown didn't happen or Windows didn't sign in by itself.
The schedule is stored as Windows scheduled tasks, so it outlasts the window and survives restarts. A shutdown missed while the PC was off is dropped, so it can't fire when the PC next starts.
One click copies the exe to a fixed folder for your user only, adds it to the Start menu and to Windows' app list, and points the schedule at it. Moving or deleting the download can't stop the shutdowns.
The app asks gitlab.com for the latest release when the window opens, sending only its version number. Nothing is downloaded until you click, and the file is checked against the release's checksum first.
The Log button opens a record of countdowns, waits and shutdown commands, so you can see why the PC did or didn't go off.
It does one job, and these are its edges.
It runs on the .NET Framework that ships with Windows, so there is nothing else to install.
ShutdownScheduler.exe.To remove it, open Windows Settings > Apps > Installed apps, find Shutdown Scheduler and choose Uninstall. That turns off the schedule and removes the app, its settings and its log.
