Scheduled shutdown
From 1 minute up to 7 hours. Your PC shuts down when the time runs out.
When time runs out, your PC turns itself off
Set the time with a few button presses and click Run. A flip clock counts down to zero, then your PC shuts down. It can put the PC to sleep instead, and it shows you the last screen before shutdown the next time you turn it on.

What it does
There is no settings window.
You set the time and click Run, and that's it.
It always starts at 5 minutes and Shut down.
Sleep
Pick the moon to put the PC to sleep instead of shutting it down.
Last screen before shutdown
The screen right before shutdown is saved and shown in your browser the next time you turn the PC on.
Flip clock
The time left flips by on hours : minutes : seconds cards, easy to read from across the room.
Set the time with buttons
Add and subtract with −5 −1 +1 +5, or jump straight to 5 10 30.
No accidents
While counting, the time buttons and power options hide. Only Stop remains.
Reliable shutdown
It never stays on all night stuck on a "Save changes?" prompt. Save your work before you click Run.
One executable
No admin rights and no settings file. For the portable version, just unzip it.
Check the last screen in the morning
If you left a download or backup running and went to bed, what you want to know in the morning is whether it finished.
KTimer saves the screen right before it shuts down the PC.
The next time you turn it on and sign in, it opens that screen in your default browser.
- Time's up The screen of the monitor the mouse was on is saved.
- PC shuts down It doesn't wait, even if another program tries to hold it up.
- Next time you turn it on When you sign in, your browser opens and shows that screen. There's nothing you need to do.
- With several monitors, leave the mouse on the monitor with the window you want to check before you walk away.
- This screen is only for shutdown. With sleep, the screen is still there when you wake the PC.
Shut down, or put to sleep
Choose in the two options in front of the Run button.
The power symbol shuts down, and the moon puts the PC to sleep.

Sleeping…

One window with just a clock and buttons.
How to…
Fall asleep to a movie or music
A movie usually runs about 2 hours. Press 30, add enough with +5, click Run and go to sleep. Your PC shuts down around the time it ends.
Leave a download, backup or video conversion running
Schedule the time the job should take, plus a little extra (up to 7 hours). The next time you turn the PC on, the last screen before shutdown opens, so you can check right away whether the job really finished.
You have unsaved documents
When the time comes, other programs can't hold up the shutdown, so the PC reliably turns off. But unsaved work won't be kept, so save it before you click Run.
Cancel or change the time
Click Stop to stop the countdown and bring back the time buttons. Change the time and click Run to count down again from the new time. To cancel completely, you can also just close the window.
The window is in the way
Minimize the window and it keeps counting in the background. To check the time left, open it again from the taskbar.
You can't find the window
Start KTimer again. Instead of a new window, the one already counting comes to the front. Only one timer can run at a time.
Set the time quickly
Common times like 5, 10 and 30 minutes take a single button press. For 1 hour, press 30 and then +5 six times. For 45 minutes, press 30 and then +5 three times. Fine-tune by the minute with +1 and −1.
How long can I set?
From 1 minute to 7 hours. Going below or above simply stops at the limit. Pressing −1 again and again never goes below 1 minute.
