Autoshutdown option in windows xp

Mukesh maid:

There is no need to use scheduler. You can accomplish this using hibernation. Hibernation is the process whereby Windows saves the current state of your machine (open files, windows, etc.) and shuts down in a hibernated state. Then when you start back up, it is all as it was before it was shut down. Right click on any blank part of your desktop, select Properties. The window appearing will be titled Display Properties, but this is about the system, not just display.

Then select the tab for Screen Saver, and click on the button in the lower right corner labeled Power. When this window opens, make sure you are able to hibernate. Click the tab titled Hibernate and make sure Enable Hibernation is checked. Then go to the Power Schemes tab, and the bottom set of choices (System hibernates) is for you to choose the amount of time after which the system will hibernate. Click the drop down arrow and select a time. Then, when the system has been idle for that amount of time, it will automatically hibernate, and you don't have to worry about it any more.

I believe from memory that you can use Task Scheduler to do this and many other things.
Just goto the HELP section in the Start menu and type Task Scheduler

Hope it helps =)
