I've uploaded a small program to my site, that can change the Screensaver
timeout automatically. Download
http://windowsxp.mvps.org/utils/SetScrTimeout.exe
Save the file to a folder of your choice. (C:\Tools)

Usage
=====

To set the screensaver timeout value to 60 seconds, use this command:

C:\Tools\SetScrTimeout.exe 60

So, create two shortcuts as per your requirement. One with 60 second
timeout, and the other with 3600 seconds ( 1 hour).

Shortcut Target and command-line would be:

"C:\Tools\SetScrTimeout.exe" <timeout value in seconds>

Example:
"C:\Tools\SetScrTimeout.exe" 3600

Using the GUI means it communicates the changes to the system immediately,
using API call. REG files don't do that. That's the reason you need a
program to accomplish the task, using SystemParametersInfo API.

I don't understand... if I use the GUI to change the timeout, it works
without a reboot. WHy this case, I need to reboot ?
