A. Windows Vista and later support wake timers that scheduled tasks can use, allowing a system to automatically wake from sleep or hibernate at a certain time. This can be useful to wake machines so they can check for updates or changes in policy.
To use a local scheduled task:
- Launch Task Scheduler (Start, Accessories, System Tools, Task Scheduler).
- Select the Create Task action.
- Name the task under the General tab and, optionally, provide a description.
- Select the Triggers tab, select New, and specify to begin the task on a schedule. Select Daily or Weekly (or whatever you need) and the recurrence. Specify the start time (e.g. 2:00:00 a.m.) and click OK.
- Under Actions, select the program or task you want to run. For example, to install important updates from Microsoft, I could set the program to
- Click the Conditions tab, select Wake the computer to run this task, and click OK.
%windir%\system32\wuauclt.exe /detectnow
You could always have a script that runs the install then runs
shutdown –s
to shut down the machine, or use other options that work best for your environment.
