How do I block internet access on my computer or possibly have a password just to use computer?

Answer 1

if you have Verizon DSL, Yahoo on line protection adds password protection for Internet use among other items.

Answer 2

If you are using windows XP then go to the control panel and select users. From there select the account(s) you have and then click on the set password option. To just block the internet unplug the cable from the back of the computer (phone or network) and hide the cable. Some home routers offer the option of setting internet restrictions (time of day, certain sites, block all etc.).

Answer 3

You can lock your PC with a hotkey or from the system tray. To unlock the computer you must enter correct password only. Unlike another similar computer lock software that cannot lock Ctrl+Alt+Del on a computer running Windows XP, our Lock My PC runs own keyboard driver to block such key combinations.
