Hi All Experts,

I need to use batch file to implement the following points

1/. user computer must be screen saver with password protected.
2/. screen saver time out value = 300seconds (5minutes)
3/. user can not change screen saver or the screen saver time out value.

when I run the batch file, it will implement those policy.

so please help.

Thanks

Sure, a batch file will set the values you requested:
reg add "hkcucontrol paneldesktop" /v screensaverissecure /d 1
reg add "hkcucontrol paneldesktop" /v ScreenSaveTimeOut /d 300

But to prevent the user from changing their "user" settings goes against the design.  You can only lock them down via policy, unless you're also going to manipulate the permissions on the desktop key, which is highly advised against.  Though even if you would go that route, it would mean a separate instance because that could only be changed by an admin...

Be Reminded window XP is no longer supported by Microsoft.

You can do this, set all setting for screen saver on window as adminstrator
and  then change the registry key to hide those setting from user
from the tools such as http://www.pctools.com/guides/registry/detail/170/

 For group policy, I am NOT quite sure doing Group policy on XP  easier or more time-consuming than on window 7
(Note: The following link is just for your reference at option2- and option-3 ,how to solve your similar issue on window 7 but not on xp, http://www.sevenforums.com/tutorials/15322-screen-saver-password-protection-enable-disable.html)

Hope understand your question completely.If not, please point it out

Group Policy would be the best way to handle this, even if you are not in a domain environment.  You can edit the local security policy to enact those changes.
