Maybe this will help?

You can separately password protect your internet connection. Keep it disconnected always. Connect it when you want, through password enabling. That is what I do.

Sir,

I want to do with any software not windows configurations.

There are millions of sites with instructions on this,

Protect your computer with a password - Windows - Microsoft

My favorite way to keep children doing thier homework and chores was to place a post it note with what they were to accomplish before us (the parents) got home. If all was completed, they got the password which was changed daily, to access the network.

Hello Friends,

As far as I can tell, it's not possible to block access to sockets to set the firewall per-user. For Windows 7, it appears that a third-party software can be used to manipulate the Windows Firewall per-user, but this appears not to apply to Windows XP. If simply blocking use of a web browser is sufficient, you could set the permissions on iexplore.exe and any other browsers you have to deny access to the Guest account. This would effectively prevent them from using a web browser (assuming you have no others installed). You could also deny access to other internet-based applications. Just keep in mind that this will not guarantee the user can't access the internet, only inhibit general users. Even a modestly skilled user could bring his thumb drive with his own browser and run it from the guest account.

Thanks and Regards
Steven Arnold
