How to Schedule a Windows Reboot at a Later Time

Updated on 8/26/2008 with corrected information!

Window’s simple shutdown command works well, but has some major drawbacks. The major one is that it will only schedule a reboot up to 10 minutes into the future (600 seconds). Linux’s shutdown command makes this easy, just issue the command ‘shutdown -r +60’ for example to reboot an hour in the future.

No such luck in Windows, you need to download a separate program to do this. It is a sysinternals program, you might remember sysinternals from such utilies like FileMon and ProcessMonitor.

The program we use for this is called PsTools and more specifically the file psshutdown.exe.

Place psshutdown.exe into a directory for future use, for this example we will use c:\tools\.

Easiest Method:

Type the following command into the command prompt:

c:\tools\psshutdown.exe -r -f -c -t 02:00 /accepteula

PSshutdown will respond with:

Local system is scheduled to reboot in 15:08:00.

If all goes will, Windows will reboot at 2:00am, or your specified time. This command will start a system service with the psstools scheduling program, PSSDNSVC.EXE.

Alternate Method:

Then open a command prompt and type the following command:

at 2:00am c:\tools\psshutdown.exe -r -f -c -t 10 /accepteula

This will result in:

Added a new job with ID = 1

You can verify this task has been added by looking at the Scheduled Tasks – the job name will be At1 if you haven’t scheduled any other tasks via the command line.
